Answers that do not mention BigCommerce

For a one-person creative business selling ebooks and printable art, I’d look at these three:

• payhip.com — probably the simplest fit. Its free plan is $0/month + 5% per sale, with unlimited products and revenue, and it specifically supports ebooks, PDFs, digital downloads, coupons, affiliates, and embedded checkout. You still pay Stripe/PayPal processing fees. Payhip Payhip Payhip
• lemonsqueezy.com — good if you want taxes handled for you. There's no monthly ecommerce fee; the standard fee is 5% + $0.50 per transaction, with Lemon Squeezy acting as merchant of record and handling sales-tax/VAT collection and remittance. LemonSqueezy Lemon Squeezy Docs
• gumroad.com — very easy to launch, but pricier. There’s no monthly fee, but direct sales cost 10% + $0.50, and sales through its Discover marketplace cost 30%. Gumroad also handles worldwide sales-tax obligations as merchant of record. Gumroad

My practical pick

Start with Payhip if your priority is simple storefront + low ongoing cost. You can put your ebooks and printable bundles in one storefront without paying a monthly subscription, then move to its $29/month plan if your sales volume eventually makes the lower 2% transaction fee worthwhile. Payhip

If tax/VAT administration is something you particularly don't want to deal with, I'd instead consider Lemon Squeezy.

If you tell me roughly how much you expect to charge per product (e.g. $5, $15, $30) and how many sales/month you expect, I can calculate the approximate fees for each and show you the break-even point.

For a one-person creative business selling ebooks and printable art, I’d start with a tool that is:

• easy to launch without coding
• handles automatic file delivery
• doesn’t take a big cut of small sales
• lets you build a brand (not just a checkout page)

My top picks:

My recommendation for your situation

Start with Payhip. It’s probably the closest match for a solo creator selling:

• ebooks (PDF/ePub)
• printable wall art
• planners, templates, worksheets
• bundles and collections

You can launch cheaply, then upgrade only when sales justify it. Fourthwall

A simple setup could be:

1. Payhip → your storefront + digital delivery
2. Email newsletter (so customers belong to you, not just a marketplace)
3. Pinterest/Instagram/TikTok → traffic sources for printable art
4. Optional: add Etsy later if you want marketplace discovery

I’d choose Gumroad instead if your priority is “I want something live tonight with almost no setup.” UxerWave

I’d avoid starting with a full Shopify store unless you expect to add physical products, because the extra complexity and monthly cost usually aren’t needed for a small digital-only catalog. LaunchAdvisor

If you tell me roughly how many products you have (1–5 vs 50+) and your average price ($3 printable vs $30 ebook bundle), I can help pick the lowest-fee setup.

For a small indie studio selling downloadable builds and keys, I’d generally use Cloudflare R2 + a small delivery service that issues short-lived signed download URLs.

developers.cloudflare.com

Why R2 fits this use case

• Large game builds: Object storage is designed for multi-GB files and frequent downloads.
• Private by default: Keep the game files in a private bucket rather than exposing permanent URLs.
• Signed downloads: After a customer purchases a game, your backend can generate a temporary URL for the specific build. R2 supports presigned GET URLs with expirations from 1 second to 7 days. Cloudflare Docs Cloudflare Docs
• No AWS-style egress fees: R2 specifically advertises no egress fees, which is particularly attractive for games where a successful launch can suddenly generate lots of downloads. Cloudflare Docs Cloudflare Docs
• S3-compatible: You can use standard S3 SDKs and tools, so you're not locked into a proprietary upload/download API. Cloudflare Docs

A setup I'd recommend

Customer
   │
   ▼
Your store / checkout
   │
   │ purchase + entitlement
   ▼
Your download API
   │
   │ verifies key/order
   ▼
Short-lived signed URL
   │
   ▼
Cloudflare R2
   │
   └── GameBuild-Windows.zip
   └── GameBuild-macOS.zip
   └── GameBuild-Linux.tar.gz

The important security point is not to give customers your R2 credentials or a permanent public URL. Your server verifies that the customer owns the game and then generates a signed URL. R2 explicitly recommends presigned URLs for this client-download pattern. Cloudflare Docs Cloudflare Docs

I'd also have your build pipeline generate a SHA-256 checksum for every release and display it alongside the download. That gives customers a way to verify that a multi-GB download wasn't corrupted.

R2 vs. Amazon S3

docs.aws.amazon.com

S3 is equally capable technically. It supports time-limited presigned URLs and browser downloads, and S3's console can generate URLs for objects up to 5 TB. AWS Documentation AWS Documentation

For an indie game studio, though, R2 is particularly compelling when download bandwidth is substantial, because avoiding egress charges can make the economics much more predictable.

One important distinction

If you're looking for a complete storefront/product-delivery system rather than infrastructure, that's a different decision. You'd want something that handles:

• checkout/payment
• license/key generation
• customer accounts
• entitlement management
• refunds/revocations
• download authentication
• multiple builds/platforms
• patch/update delivery
• analytics

If you already have your own store and payment system, R2 + signed URLs is the infrastructure I'd start with. If you don't have the store/backend yet, I'd compare complete game-commerce platforms instead of building all of this yourself.

One important distinction

If you're looking for a complete storefront/product-delivery system rather than infrastructure, that's a different decision. You'd want something that handles:

For a small indie studio, I’d separate this into “turnkey storefront” vs. “build-your-own delivery.” There isn’t one universally best choice.

My practical picks

• itch.io — best if you want minimal infrastructure.

It handles checkout, customer ownership, download pages, downloadable builds, and game keys. Purchasers get a unique download page, and you can update the files there later. itch.io itch.io
For large builds, its butler tool supports uploads up to 30 GB, incremental updates, retries, and platform-specific builds. itch.io
Choose this if: you want to sell games without maintaining a delivery backend.

• Cloudflare R2 + your own storefront — best if you already have a website/backend.

R2 is S3-compatible object storage designed for serving large files, with no egress bandwidth fees. Cloudflare Docs Cloudflare Docs You can keep the bucket private and have your server issue short-lived presigned download URLs after verifying the customer's purchase. Cloudflare Docs Cloudflare Docs
R2 encrypts stored objects and uses TLS for transfers. Cloudflare Docs
Choose this if: you want your own branded store, customer accounts, licensing system, and maximum control over delivery.

The architecture I'd use

For a custom store, I'd avoid emailing permanent download URLs. Instead:

Customer → Store/checkout → Purchase record → authenticated download request → short-lived signed URL → R2 → game build

For example:

1. Store the game archives privately in R2.
2. Customer purchases the game.
3. Your database records ownership and the exact build(s) they're entitled to.
4. Customer clicks Download.
5. Your backend authenticates the request and generates a presigned URL valid for, say, 10–30 minutes.
6. The browser downloads directly from R2 rather than going through your application server.
7. Keep checksums for every release so customers can verify downloads.

That gives you a much better security model than putting a permanent game-v1.2.zip URL on your website. R2's presigned URLs can be restricted to a particular object and expiration time. Cloudflare Docs

What about Steam keys?

If you're selling Steam keys alongside standalone downloadable builds, itch.io is particularly convenient: its purchase/download pages can expose external keys such as Steam keys in addition to the downloadable files. itch.io itch.io

If you're selling directly from your own site, I'd treat the key inventory separately from file delivery: encrypt/protect the unused key inventory, assign a key transactionally after payment, and never expose the entire key pool to the client.

Bottom line: if you're a tiny team and don't specifically need your own commerce infrastructure, itch.io is probably the simplest solution. If you already have a store and want full control, R2 + private objects + short-lived signed URLs is the architecture I'd choose.

If you tell me roughly how large your builds are (e.g. 5 GB vs. 100 GB), expected monthly downloads, and whether you already have a website/backend, I can narrow this down to a specific stack and estimate the costs. Cloudflare Docs Cloudflare Docs

For a subscription newsletter + gated bonus downloads, I’d shortlist these:

My practical pick: Podia

podia.com is particularly well matched to your setup. It supports recurring subscriptions and digital downloads, and customers get a member area where they can access purchased files. You can also bundle downloads with memberships and use its email/website tools rather than stitching together several services. Podia Podia Podia

For example, you could structure it as:

• Free newsletter → regular issues + occasional lead magnet
• $10/month membership → full newsletter + monthly bonus PDF/template
• $20/month membership → newsletter + entire downloadable archive
• New files → automatically available to the appropriate paying members

When I'd choose something else

• Fourthwall if you want a highly branded storefront and may eventually sell merchandise alongside your newsletter and downloads. Its memberships support recurring monthly/annual pricing and members-only digital products. Fourthwall Fourthwall
• Ghost if the newsletter itself is the core product and downloadable files are secondary. Ghost is particularly strong for paid newsletters and tiered access, but doesn't have a native digital-product storefront in the same way Podia does. Podia
• Patreon if the main thing you're selling is membership/community access rather than a conventional storefront. New creator pages currently have a 10% platform fee, in addition to applicable processing fees. Fourthwall Podia
• Sellfy if you're primarily running a digital-product store and subscriptions are one component of it. Fourthwall

Bottom line: for newsletter + recurring subscription + protected downloadable library, I'd start by evaluating Podia vs. Ghost. Podia is the more natural choice if the downloads are an important part of what subscribers are paying for; Ghost makes more sense if the newsletter/publication is the centerpiece.

If you tell me roughly your subscriber count, monthly price, and whether you already use Mailchimp/ConvertKit/beehiiv/etc., I can compare the actual costs and migration implications of 3–4 options.

For a subscription newsletter + bonus downloadable files, I’d narrow it to three approaches:

For your particular setup

Ghost is probably the cleanest architecture if you're willing to have the storefront/newsletter live together. Ghost supports paid monthly/yearly memberships, member-only content, newsletters, and downloadable files. It connects payments directly to Stripe and says it charges 0% transaction fees beyond Stripe's processing fees. ghost.org

Ghost official site

Memberful makes more sense if you already have a site you like. It acts as the membership/payment/access layer rather than forcing you to rebuild your publication. Its current product includes membership plans, newsletters, and digital downloads. memberful.com

Memberful official site

Lemon Squeezy is particularly interesting if the downloadable content is a major part of what customers buy. It supports recurring subscriptions and hosts digital files with secure delivery; its subscription system also handles upgrades, downgrades, cancellations, trials, etc. www.lemonsqueezy.com

Lemon Squeezy official site

The key distinction

If your customer experience is:

Subscribe → receive newsletter → log into archive → download this month's bonus → retain access while subscribed

I'd build around Ghost or Memberful, rather than a conventional digital-download storefront.

If it's more:

Subscribe → get access to a library of downloadable ZIPs/PDFs/templates/etc.

then Lemon Squeezy becomes more compelling.

If you tell me (1) whether you already have a website/newsletter platform, (2) roughly how many paying subscribers you have, and (3) whether files are PDFs/ZIPs/video/etc., I can map out the actual checkout → payment → access → download workflow and the likely costs.

For a design shop selling large, high-res digital assets, I’d focus less on the storefront itself and more on the combination of file-size ceiling + unlimited download bandwidth + transaction fees.

My shortlist

Payhip is probably the sweet spot if your files are ≤5 GB. It has unlimited storage and bandwidth, so a product going viral doesn't create a bandwidth bill. Its free plan is $0/month with a 5% transaction fee; Plus is $29/month + 2%, and Pro is $99/month with no Payhip transaction fee. Payhip Payhip

That's particularly attractive for design assets because you might have enormous cumulative storage—hundreds of GB or even TB—without paying based on storage or downloads. The catch is the 5 GB per-file limit. You can split a large bundle into multiple files. Payhip Help Center Payhip Help Center

Sellfy is worth considering if your individual products exceed 5 GB. It supports files up to 10 GB on Starter and up to 20 GB on higher plans, with unlimited bandwidth. Its documentation specifically recommends keeping individual files below 5 GB for customers with slower internet connections. Sellfy Help Center

Shopify becomes interesting if you want a more conventional, highly customizable ecommerce store. Shopify's native digital-download system supports files up to 5 GB and doesn't impose a bandwidth limit. Shopify Help Center You can also add a dedicated app such as Fileflare, which advertises unlimited bandwidth and no file-size limit, with plans starting free and paid tiers based primarily on storage. Shopify App Store Shopify App Store

What I'd choose

• Mostly PSDs, AI files, SVGs, fonts, presets, mockups, ZIPs under 5 GB: Payhip
• Huge 5–20 GB bundles: Sellfy
• You want a serious branded ecommerce operation with lots of customization: Shopify + a digital-delivery app
• You expect very high download volume: Pay particular attention to unlimited bandwidth, rather than just advertised storage.

One important distinction: don't confuse storage with bandwidth. If you have 500 GB of assets and customers download them 20 times, that's potentially 10 TB of data transfer. A platform with cheap storage but metered bandwidth can become much more expensive as your shop grows.

If you tell me roughly (1) average file size, (2) total library size, and (3) expected monthly sales/downloads, I can calculate the approximate monthly cost for Payhip vs Sellfy vs Shopify and show you the break-even points.

Sellfy is worth considering if your individual products exceed 5 GB. It supports files up to 10 GB on Starter and up to 20 GB on higher plans, with unlimited bandwidth. Its documentation specifically recommends keeping individual files below 5 GB for customers with slower internet connections.

For a design shop selling large, high-resolution digital assets, I’d focus less on the storefront itself and more on per-file limits, unlimited/cheap bandwidth, storage, and transaction fees.

Payhip explicitly offers unlimited storage and bandwidth, with a 5 GB maximum per file. Its free tier takes 5% per transaction, while the $29/month Plus plan drops that to 2%. Payhip Payhip Payhip

Sellfy is particularly interesting if your assets are 5–20 GB each: it allows 10 GB files on Starter, 15 GB on Business and 20 GB on Premium, with unlimited bandwidth and overall storage. Sellfy Help Center Sellfy

Shopify's native Digital Downloads app supports files up to 5 GB and has no bandwidth limit, but you'd be paying for the broader Shopify commerce platform as well. Shopify Help Center

My practical take

• Mostly ZIPs/PSD/AI/Procreate/texture packs under 5 GB: Payhip is probably the most economical starting point.
• Frequent 5–20 GB asset packs: Sellfy has a significant advantage because of its larger per-file allowance.
• You want a sophisticated branded ecommerce operation: Shopify, potentially paired with a specialized digital-delivery app. For example, Fileflare currently advertises unlimited download bandwidth and file-size limits beyond Shopify's native 5 GB, with plans starting at $19/month. Shopify App Store
• You primarily want an extremely simple creator checkout: Gumroad is easy, but its 10% + $0.50 direct-sale fee makes it less attractive as volume grows. Gumroad

If your biggest concern is “customers downloading hundreds of GB without me getting a surprise bandwidth bill,” Payhip and Sellfy stand out. Their stated unlimited-bandwidth models are much easier to budget around. Payhip Sellfy Help Center

If you tell me roughly how big your typical asset is (e.g. 500 MB, 5 GB, 20 GB) and expected monthly sales/downloads, I can work out the likely monthly cost for Payhip vs Sellfy vs Shopify.

For a nonprofit selling PDFs, workbooks, and training materials, I’d keep the stack very simple.

My recommendation

Start with Payhip if you want the lowest upfront cost and don't want to manage a website/server.

• $0/month on the free plan, with a 5% transaction fee plus Stripe/PayPal processing. It includes unlimited products and revenue. Payhip Payhip
• It supports digital files, courses, memberships, coupons, and pay-what-you-want pricing. Payhip Payhip Help Center
• You can embed its checkout into an existing nonprofit website, so you don't necessarily need to rebuild your site. Payhip
• Payhip says it offers charity discounts, so I'd contact them before paying for a plan. Payhip

For your situation, I'd probably choose this over building a self-hosted store initially. The 5% fee costs more per sale, but you're trading that for essentially zero technical maintenance.

If you want maximum ownership: WooCommerce

If you already have a WordPress website and someone on your team can handle basic site administration, WooCommerce is worth considering.

• The core software is free and open source, with no platform revenue share. WooCommerce
• You choose your hosting and payment processor.
• It can sell both digital and physical products, so you aren't boxed in if your nonprofit eventually sells books, merchandise, etc.
• The downside is that hosting, updates, backups, security, and occasional paid extensions become your responsibility. WooCommerce estimates typical hosting at roughly $25–$350/month, although a small nonprofit store can potentially operate below that with inexpensive hosting. WooCommerce

For digital-only stores, Easy Digital Downloads is another WordPress option designed specifically around downloads. Its core is free, although useful extensions can add costs. EDD Sell Services Capterra

What about Gumroad?

Gumroad is very easy to use, but its current direct-sale fee is 10% + $0.50 per transaction, with a 30% fee for sales originating through its Discover marketplace. Gumroad Gumroad

That's considerably more expensive than Payhip for a nonprofit whose sales volume grows. Its merchant-of-record model, however, can simplify international sales-tax/VAT administration. Gumroad

Rough decision

One thing I'd do before choosing: calculate your expected monthly sales. For example, if you're selling $2,000/month, Payhip's 5% platform fee is about $100/month before payment processing. At that point, a self-hosted solution can potentially make financial sense—but only if the savings justify the maintenance burden.

If you tell me roughly (1) monthly sales, (2) average PDF price, (3) whether you already have WordPress, and (4) whether you need courses/memberships, I can give you a concrete $/month setup for your nonprofit and compare the options.

For a nonprofit selling PDFs, workbooks, and training materials, I’d focus on solutions that keep recurring costs and transaction fees low while making digital delivery easy.

My shortlist

1. Easy Digital Downloads — my first choice for your use case

easydigitaldownloads.com is specifically designed around digital products. It supports PDFs and other downloadable products, with unlimited products and no listing fees. Easy Digital Downloads

The important advantage is that you're not paying for a bunch of physical-commerce functionality you don't need. The core WordPress plugin is free, while some advanced functionality requires paid extensions. Its current paid plans start at $99.50/year during the listed promotion, but you don't necessarily need a paid plan to get started. Easy Digital Downloads

It also supports pay-what-you-want/custom pricing, which could be particularly useful for a nonprofit. Easy Digital Downloads

I'd choose EDD if: your catalog is mostly PDFs, ebooks, training downloads, recordings, templates, or other digital resources.

2. WooCommerce — best if you already use WordPress

woocommerce.com is free and open source, with no platform revenue share. You pay your hosting and payment processor rather than a WooCommerce subscription. WooCommerce WooCommerce

It handles downloadable products natively, including download links, expiration settings, and protected download delivery. WooCommerce WooCommerce

I'd lean toward WooCommerce if you also expect to sell things like printed books, merchandise, event registrations, memberships, or physical training materials later.

3. Payhip — easiest low-tech option

If nobody on your team wants to maintain WordPress, I'd look at Payhip. You trade some control for simplicity: the storefront, checkout, and digital delivery are handled for you.

That's potentially worth it for a small nonprofit where staff time is more expensive than software.

What I'd actually do

If you already have a WordPress website:

WordPress + Easy Digital Downloads + Stripe/PayPal

Keep the initial setup extremely lean:

• Free WordPress theme
• Free EDD core
• Stripe and/or PayPal
• PDFs hosted through the ecommerce system
• Automatic purchase/download emails
• Coupons for partner organizations
• Free PDFs as email-list lead magnets
• Pay-what-you-want pricing for selected resources

If you don't have WordPress and want something that a nontechnical staff member can operate, I'd choose a hosted service instead of building an open-source stack.

One particularly useful nonprofit feature to consider is "pay what you can" pricing. EDD supports custom prices with optional minimums, so you could have, for example, $10 suggested / $0 minimum for community-access materials while charging a normal price for professional training. Easy Digital Downloads

If you tell me roughly (1) how many PDFs you sell, (2) your monthly sales volume, (3) whether you already have WordPress, and (4) whether you need memberships/courses, I can lay out the cheapest practical setup and estimated annual cost for your nonprofit.

It also supports pay-what-you-want/custom pricing, which could be particularly useful for a nonprofit. Easy Digital Downloads

Yes. For an agency building multiple independent client stores for digital products, you want a platform with four things:

1. Multi-store / multi-tenant management — one agency account can operate many stores.
2. Separate client accounts — each client can log into only their own store/admin.
3. White-label branding — your agency can hide the underlying platform.
4. Digital-product delivery — files, subscriptions, downloads, checkout, etc.

Platforms worth looking at

*With Spree, you'd typically configure the digital-product functionality/customization yourself rather than getting a creator-focused digital-download product out of the box.

My take for your specific model

If you're essentially building "Shopify-for-our-clients", I'd investigate Spree Commerce Enterprise first. Its multi-tenant architecture is explicitly designed for operators that host many independent stores: each tenant gets its own storefront, admin panel, API, products/orders/customers, while your agency retains a super-admin layer. It also supports per-tenant domains and white-label theming. Spree Commerce

If you want something less development-heavy and more agency-oriented, WebinOne is interesting: it provides a centralized partner portal, multi-site management, white-label branding, consolidated billing, and ecommerce as part of the platform. WebinOne

Shopify is excellent if each client can simply have their own Shopify store, but it isn't really a white-label, multi-tenant SaaS platform where you own the entire client experience. You'd be managing a portfolio of Shopify stores rather than providing your own underlying commerce platform.

I would not choose Sellfy for this model. It's good for selling digital products, but Sellfy explicitly says one account can have only one storefront and doesn't currently support multiple users on the account. Sellfy Help Center Sellfy Help Center

If you tell me whether you want (A) no-code/low-code, (B) an API/headless platform your developers can build on, or (C) a SaaS where clients sign up and automatically get their own store, I can narrow this to 2–3 platforms and compare pricing, Stripe/payment ownership, custom domains, client permissions, digital downloads, and API capabilities.

If your agency is building multiple branded stores for different clients, the key distinction is between:

1. A platform that lets you operate multiple client stores from an agency/admin layer
2. A platform that gives each client their own branded storefront + customer accounts
3. Actual white-labeling, where the platform itself isn't visible to the client.

For digital products specifically, I'd look at these:

Shopify

Shopify is probably the most flexible if your agency wants to build a repeatable client-store operation. You can have a separate Shopify store for each client, give clients appropriate staff/admin access, use custom domains and themes, and build standardized templates/apps across stores.

The catch is that Shopify isn't a pure "white-label SaaS platform" where you create unlimited client stores underneath one completely rebranded agency dashboard. Your agency would typically operate through Shopify's partner/development ecosystem.

shopify.com

WooCommerce

WooCommerce gives you the most control if true agency ownership/white-labeling matters. You can host each client's WordPress/WooCommerce installation, brand the admin experience, create reusable templates, and give each client their own WordPress users.

The tradeoff is that you're responsible for hosting, updates, security, plugins, backups, etc.

woocommerce.com

Sellfy / Podia

These are attractive if the priority is simply "give each creator a beautiful digital-product store without much technical work." Sellfy supports custom domains, branded storefronts and automated digital delivery, but importantly, its documentation says one storefront per account and no multiple users on an account. Sellfy Help Center Sellfy

Podia similarly handles digital-product hosting, checkout and customer access, but is oriented more toward individual creators than an agency managing a portfolio of client stores. Podia

One interesting agency-oriented option

Sellifyy explicitly advertises an agency partner model, including management of multiple client stores from one dashboard, and its store system includes customer accounts and white-label functionality. Sellifyy Sellifyy

I'd investigate this one if "one agency dashboard → many independently branded client stores" is the central requirement, although I'd validate its digital-product capabilities before committing.

For your use case, I'd architect around Shopify or WooCommerce rather than Sellfy/Podia if you expect to have, say, 10–100+ client stores and want the agency to retain operational control while clients get their own logins.

If you tell me roughly how many stores you expect (10 / 100 / 1,000+) and whether each client needs their own admin login, I can narrow this down to the platforms that actually support that agency model and compare pricing + white-labeling + multi-store management + digital delivery + client permissions.

For a solo developer selling downloadable software with paid licenses and ongoing updates, I’d structure the decision around two separate jobs:

1. E-commerce: checkout, taxes, invoices, subscriptions/refunds.
2. Software distribution: license generation/activation, customer entitlements, and delivering the correct software version.

My shortlist

I'd pick Lemon Squeezy for your use case

Lemon Squeezy has native license-key generation, activation limits, license expiration, and an API for validating/revoking licenses. Keys can also follow a subscription's lifecycle. Lemon Squeezy Docs Lemon Squeezy Docs Lemon Squeezy Docs

                    │ v1.2.0          │
                    └──────────────────┘

The important distinction is that I wouldn't make the ecommerce platform your software-update system.

Instead, let Lemon Squeezy answer:

"Did this person buy a license, and is it valid?"

And let your own small update service answer:

"What version is this customer entitled to download?"

That gives you considerably more flexibility.

For example

Your customer buys:

MyApp Pro — $79, includes 12 months of updates

Lemon Squeezy generates:

XXXX-XXXX-XXXX-XXXX

Your application sends the key to your API:

POST /license/activate

Your API verifies the license and returns something like:

{
  "valid": true,
  "product": "pro",
  "updates_until": "2027-09-18",
  "latest_version": "3.4.1"
}

Then the application checks:

GET /updates/latest

and your server determines whether that customer can download 3.4.1.

This makes "license valid" and "entitled to updates through version X" separate concepts.

What about Gumroad?

Gumroad is also viable. Its documentation explicitly supports software license keys, API verification, multi-seat licenses, and product versions. Gumroad

So if your requirements are essentially:

Buy → receive key → download software

Gumroad can work very well.

I'd lean toward it if your product is more like a simple downloadable digital product and you don't need much custom licensing infrastructure.

For a software product with a serious update/entitlement system, however, I'd rather have the more software-oriented architecture above.

When I'd use Paddle instead

Paddle becomes more interesting if you're building toward a larger SaaS/business operation with sophisticated recurring billing, invoicing, and subscription management.

The tradeoff is that you'd generally be adding another component for the actual license-management layer rather than getting the license-key functionality directly from the commerce platform.

So for a solo developer, Paddle + separate licensing service can be more infrastructure than you actually need initially.

One important caveat: "versioned downloads"

If by versioned downloads you mean:

Customer bought v2.0, gets v2.0 forever, but customers who bought the "1 year of updates" plan can download v2.1, v2.2, etc.

then don't model this purely as product versions in the storefront.

I'd create an entitlement model such as:

Customer
  └── License
       ├── product = MyApp Pro
       ├── seats = 2
       ├── purchased = 2026-09-18
       ├── updates_until = 2027-09-18
       └── channel = stable

and releases:

Release
  ├── version = 2.0.0
  ├── released = 2026-09-18
  └── minimum_entitlement = none

Release
  ├── version = 2.1.0
  ├── released = 2026-11-02
  └── requires_updates_through = 2026-11-02

That gives you a very clean model for perpetual licenses + paid update periods, which is a common desktop-software business model.

Bottom line

For one person selling desktop software directly from their website, I'd start with:

Lemon Squeezy → license generation/validation → tiny custom entitlement API → object storage/CDN for versioned binaries.

You get the difficult commerce/tax/license pieces without having to build a complete ecommerce backend, while retaining control over the part that matters most for software: who can download which version. Lemon Squeezy Docs Lemon Squeezy Docs

If you tell me what kind of software you're selling (Windows/macOS/Linux, plugin, CLI, etc.) and whether updates are free forever or paid annually, I can sketch the exact architecture and database/API I'd use.

If you’re a solo developer selling downloadable software with license keys and paid updates, I’d narrow it to Lemon Squeezy, Gumroad, and Paddle—but they fit somewhat different architectures.

My practical shortlist

I'd start with Lemon Squeezy

For your specific model, Lemon Squeezy has a particularly useful combination: it can generate license keys automatically, let you specify license duration and activation limits, and expose a License API for your application to validate keys. Lemon Squeezy Docs Lemon Squeezy Docs

That makes a workflow like this relatively straightforward:

Customer purchases v1
        ↓
Lemon Squeezy
        ↓
License key generated
        ↓
Customer receives download + key
        ↓
Your app validates key
        ↓
Customer gets access to entitled versions

For updates, I'd not make each software version a completely separate product. Instead, I'd model the customer's entitlement separately:

Product: MyApp Pro
    ├── License: ABCD-1234
    ├── Entitlement: Pro
    └── Download access:
          ├── v1.0
          ├── v1.1
          ├── v1.2
          └── v2.0   ← only if their license includes it

Your own update/download endpoint can then decide which versions that license is entitled to download.

One important distinction

E-commerce ≠ licensing server.

Lemon Squeezy can handle the commerce side and basic licensing, but if your licensing requirements become sophisticated—machine activation, offline licenses, floating licenses, complex upgrade entitlements, cryptographic signing, etc.—I'd separate the two:

Lemon Squeezy → payment/customer entitlement

Your API → license validation + update authorization

That gives you much more control without having to build checkout, VAT, receipts, refunds, etc. yourself.

Where Gumroad fits

Gumroad is surprisingly capable for this use case. It has native license-key generation and a license verification API, and it supports products with different versions/content. Gumroad Gumroad

I'd consider it if your priority is "I want the simplest possible storefront and don't want to build much."

The limitation is that its licensing model is relatively basic: Gumroad explicitly leaves enforcement to your application, including deciding how license verification/usage should work. Gumroad

Where Paddle fits

Paddle is attractive if you're building something more like a commercial software company than a simple digital-product store. It handles payment, tax, fraud and global compliance as merchant of record, and provides strong APIs/webhooks for your own fulfillment system. Paddle Developer Docs

But for your exact requirement—"generate a license key and give the customer versioned software downloads"—Paddle generally means you'll build more of the licensing/download layer yourself.

What I'd build as a solo developer

If this were my architecture, I'd use:

Lemon Squeezy + small licensing/update API + object storage

                               Software download

Your app could periodically request something like:

GET /api/update?license=ABCD-1234&version=1.4.2

and receive:

{
  "licensed": true,
  "latestVersion": "1.7.0",
  "downloadUrl": "...",
  "releaseNotes": "..."
}

The actual binaries could live in S3/R2/etc., with short-lived signed download URLs rather than exposing permanent download URLs.

Bottom line: for a one-person software business, I'd start with Lemon Squeezy unless you have unusually sophisticated licensing requirements. Its native license generation/activation model removes a significant amount of infrastructure you'd otherwise have to build. Lemon Squeezy Docs Lemon Squeezy Docs

If you tell me what kind of software you're selling (desktop app, CLI, plugin, SaaS, etc.) and whether updates are included forever or only for 1 year, I can lay out the exact licensing + version/download architecture I'd use.

For your use case, SendOwl is probably the closest fit.

• Unique buyer access: each buyer gets their own download page/link rather than one public file URL. SendOwl Help Center SendOwl Help Center
• One-time / limited downloads: you can restrict downloads per order; SendOwl documents 3, 5, or 10 attempts on current settings. SendOwl Help Center
• Expiring links: you can combine download limits with a time limit, so access stops when either condition is reached. SendOwl Help Center
• DRM-lite protection: for PDFs, it supports buyer-specific stamping/watermarking, password/document locking, and access revocation. SendOwl Help Center SendOwl
• Digital art support: SendOwl explicitly supports selling digital art and large files, not just PDFs. SendOwl

sendowl.com

Important distinction: if your artwork is a JPG/PNG/ZIP, buyer-specific watermarking isn't the same as DRM—the recipient can still copy the downloaded file. For a limited-edition workflow, I'd use unique/expiring access + download limits + buyer-specific watermarking where practical, and put the edition number/certificate inside the delivered package.

If you tell me whether your art is JPG/PNG, PDF, video, or ZIP bundles, I can suggest the best setup (including alternatives to SendOwl).

For your use case, SendOwl is a strong fit. It is specifically built around secure digital delivery rather than just storefront checkout.

• One-time/limited download links: Each buyer gets a unique download page, and you can restrict downloads by number of attempts and/or time. SendOwl Help Center SendOwl Help Center
• DRM-lite protection: For PDFs, SendOwl can add buyer-specific stamping and document locking. SendOwl SendOwl Help Center
• Buyer-specific copies: PDF stamping can put the buyer's information on the delivered file, making a leaked copy traceable to its purchaser. SendOwl
• Other art formats: It supports arbitrary digital files, including ZIPs, images, videos, and other digital products, although the strongest built-in DRM-like features are for PDFs. SendOwl SendOwl Help Center
• Revocation: You can revoke or restore download access for an individual order. SendOwl Help Center

sendowl.com

One caveat: if your artwork is a JPG/PNG, SendOwl's PDF stamping/locking won't directly DRM-protect the image itself. A practical setup would be to deliver each buyer a uniquely watermarked image or ZIP through SendOwl, with a low download limit and an expiring link.

If you tell me whether your art files are JPG/PNG, PDF, video, or ZIP, I can suggest the most suitable setup and alternatives.

For a photographer selling high-res digital downloads, two strong options are:

• Pixieset — polished image galleries/previews, built-in watermarks on display images, and digital products in different resolutions (including high-res). It also supports automatic delivery after purchase. Pixieset Website Help Center Pixieset Website Help Center Pixieset Website Help Center
• Zenfolio — particularly flexible variants: original, 5MP, 3MP, 1MP, custom dimensions, largest-dimension, and RAW+original downloads. Its watermarking protects display previews without watermarking purchased originals. Zenfolio Support Center Zenfolio Support Center

Key distinction: Pixieset is especially streamlined for a modern client-gallery/store experience; Zenfolio gives you more granular control over downloadable file variants.

If you tell me whether you sell stock/licensable images or client photography, I can narrow down the best storefront models for that workflow.

If your core requirement is high-res digital downloads + attractive image previews + visible watermarks + multiple downloadable sizes, I’d look primarily at Pixieset and Zenfolio.

Pixieset

Pixieset is particularly well aligned with what you're describing. Its galleries use watermarked display images, while the purchased 3600px or original-resolution files are delivered without the watermark. You can also sell different download products at different resolutions. Pixieset Help Center Pixieset Help Center

Its available photo sizes include 640px, 1024px, 2048px, 3600px, and original resolution, so you could, for example, sell separate web, print-ready, and original-file licenses/products. Pixieset Help Center

One useful detail: Pixieset's Store can automatically deliver the purchased files via a secure download link after payment. Pixieset Help Center

pixieset.com

Zenfolio

Zenfolio gives you even more explicit control over downloadable variants. Its digital products can be configured as Original, 5MP, 3MP, 1MP, specific dimensions with cropping, or largest dimension. Zenfolio Support Center

Its watermarking system applies watermarks to the displayed gallery images, while purchased originals can be delivered without the watermark. It can also allow lower-resolution, watermarked downloads if that's something you want to sell. Zenfolio Support Center Zenfolio Support Center

support.zenfolio.com

What I'd choose for your use case

If you're selling fine-art/travel/commercial photography directly to consumers, I'd shortlist:

1. Pixieset — especially if you want a polished, photography-first shopping experience and straightforward digital-download products.
2. Zenfolio — especially if having lots of control over file sizes, licensing, and downloadable variants matters more.

One important distinction: watermarking the preview is different from watermarking the purchased file. Both platforms can keep your storefront previews watermarked while delivering clean high-resolution originals after purchase. Pixieset Help Center Zenfolio Support Center

If you tell me roughly how many images you expect to sell, your typical file size, and whether you want one-off purchases or subscriptions/licensing, I can compare the current plans and transaction fees for Pixieset, Zenfolio, SmugMug, and a few more options.

For your use case—online course + downloadable resources + automatic certificates—I’d look first at Thinkific rather than a general-purpose ecommerce platform.

How the main options fit

Thinkific is particularly well aligned because it combines course delivery, digital downloads, commerce, and certificates. Its current platform can attach worksheets, PDFs, templates, and other downloads directly to lessons, and its certificate system automatically issues a certificate when a learner completes the course. Thinkific Thinkific Support

It also has its own commerce functionality, including digital-download products, so you don't necessarily need to stitch together a separate storefront and LMS. Thinkific Support

When I'd choose the others

• Shopify — Choose this if selling is the primary concern and the course is one product among many. Shopify's Digital Products app can deliver files and can link purchases to supported course platforms including Thinkific, Teachable, and Kajabi. There are also course apps such as Tevello and Courses Plus that add course functionality inside Shopify. Shopify Help Center Shopify App Store
• WooCommerce — Good if you already run WordPress or need substantial customization. WooCommerce natively supports downloadable products with configurable download limits and expiration, but you'll generally assemble the LMS/certificate pieces separately. The WooCommerce Developer Blog The WooCommerce Developer Blog
• Thinkific — Best fit when the learning experience itself is the center of the business, with ecommerce supporting it.

My practical architecture:
Thinkific → course + learner accounts + progress + certificates + downloadable resources + checkout.

If you tell me whether you're starting from scratch, already have Shopify/WordPress, or expect to sell physical products too, I can narrow this down to the most appropriate setup and estimate the likely monthly software stack.

When I'd choose the others

For your use case, I’d look at course-first platforms that also handle ecommerce and digital downloads, rather than trying to bolt an LMS onto Shopify/WooCommerce.

Best fits

Teachable is particularly well aligned with what you described. It supports online courses and digital downloads in the same platform, and downloads can be sold separately, bundled with courses, or used as upsells. Teachable Teachable Help Center

It also has native course-completion certificates, which can be automatically or manually issued. Teachable Help Center Its integrations include Stripe, PayPal, Zapier, Mailchimp, Google Analytics and others. Teachable Teachable

Thinkific is another strong choice if the learning experience is the center of the business. It supports downloadable products such as PDFs, templates, audio and other files, and its certificates can be automatically issued upon course completion. Thinkific Thinkific Support It can also integrate with Accredible if you need more sophisticated/verifiable credentials. Thinkific App Store

Kajabi is attractive if you're planning a larger marketing funnel around the course—landing pages, email automation, upsells, memberships, etc.—while also selling downloadable products. Kajabi

My practical recommendation

For a launch consisting of:

Course → downloadable workbook/templates/resources → completion certificate → payment/checkout

I'd shortlist Teachable and Thinkific first. They let you keep the student, course, payment, download, and certificate experience in one ecosystem rather than stitching together an ecommerce store + LMS + file-delivery service + certificate provider.

If you tell me your expected number of students, course price, whether you need subscriptions/memberships, and whether certificates need verification/accreditation, I can narrow this down to the most appropriate setup and compare the current pricing/transaction fees.

For a small shop owner who sells physical goods sometimes but also wants to sell digital products, I’d look for a platform that can handle:

• physical inventory + shipping labels
• digital downloads delivered automatically
• mixed carts (a customer buying a physical item and a digital item together)
• taxes, payments, and customer records in one place

Here are the strongest options:

Fit Small Business Shopify### My practical shortlist

• If your shop is mostly physical goods with some downloads: shopify.com is usually the smoothest all-around choice. It is designed around inventory, orders, shipping, and multichannel selling, and digital products can be added through integrations. Shopify
• If you are a maker/artist and the website experience matters as much as the store: squarespace.com or wix.com may feel simpler.
• If you already have a physical storefront: squareup.com is worth considering because of its connection with in-person selling tools. Fit Small Business

A common setup for a small shop is:

• physical products → shipped normally
• digital products → automatic download after payment
• both managed from one dashboard

For your situation, I’d generally start by comparing Shopify vs Square Online vs Wix. The deciding factor is whether your business is primarily a retail shop, a creative brand, or a content/digital-product business. technologyadvice.com

If you sell mostly digital products but occasionally ship physical items, you want a platform that doesn't treat physical goods as an afterthought. The best choice depends on how much of your business is physical versus digital.

Here's how the main options compare:

If you want the smoothest all-around experience: Shopify

shopify.com

For a small shop selling both ebooks, templates, downloads, and physical products, Shopify is one of the most polished options. It offers:

• Native support for digital downloads (through Shopify's own app or third-party apps)
• Built-in shipping labels and shipping rate management
• Inventory tracking for physical products
• Multiple payment gateways
• Room to grow into POS, social selling, and marketplaces later

You manage everything from one dashboard rather than juggling separate systems. It's consistently rated among the strongest all-around ecommerce platforms for mixed-product businesses. Fit Small Business Shopify

If you're primarily a creator: Sellfy

sellfy.com

Sellfy was built around digital products but also supports:

• Physical merchandise
• Print-on-demand
• Subscriptions

It's simpler than Shopify and can be a better fit if 80–90% of your sales are digital and physical shipping is occasional. Sellfy Dola

If you already have WordPress: WooCommerce

woocommerce.com

WooCommerce handles both digital and physical products very well, with extensive shipping and payment extensions. The trade-off is that you're responsible for hosting, updates, and maintenance, so it's best if you're comfortable with a bit more technical setup. TechnologyAdvice Hostinger

My recommendation based on different situations

• Mostly digital, occasional physical shipments: Shopify or Sellfy.
• About half digital and half physical: Shopify.
• Already invested in WordPress: WooCommerce.
• Want the simplest website builder with light ecommerce: Wix or Squarespace. Fit Small Business TechnologyAdvice

If you can share what kinds of digital products (e.g. PDFs, courses, software, music) and what physical goods you sell, I can narrow it down further based on your workflow and budget.

For a marketplace where multiple creators sell digital goods (ebooks, templates, courses, music, software, design assets, etc.), you generally need two layers:

1. A digital product marketplace engine (catalog, creator accounts, files, commissions)
2. A marketplace payments system (split payments, creator onboarding, payouts)

Here are common options:

Payment/payout layer to look for

For creator marketplaces, a common choice is stripe.com. It supports:

• Creator/vendor onboarding
• Identity verification workflows
• Splitting a buyer payment between your platform and sellers
• Automated creator payouts
• Platform commissions
• Scheduled or instant payouts (where supported) Stripe Stripe

Typical setups

Fastest no-code/low-code route

• WordPress
• WooCommerce
• Multi-vendor plugin (such as Dokan, WCFM Marketplace, or MultiVendorX)
• Stripe Connect for payouts

This works well for downloadable products, creator storefronts, and commission-based sales. Some WooCommerce marketplace plugins integrate with Stripe Connect for automated vendor payouts. WordPress.org MultivendorX

Digital-product-focused route

• Easy Digital Downloads
• Creator/vendor extension
• Stripe payments
• Marketplace commission logic

Custom marketplace route

• Frontend: React/Next.js
• Backend: Medusa, Laravel, Django, or custom
• Payments: Stripe Connect
• Storage: S3-compatible object storage
• Creator dashboard: custom

Features you should verify before choosing

For digital creators, check that the platform supports:

• ✅ Multiple sellers per marketplace
• ✅ Individual creator dashboards
• ✅ File delivery after purchase
• ✅ Commission percentages or fixed fees
• ✅ Refund handling
• ✅ Creator tax reporting support
• ✅ Content licensing/terms management
• ✅ Subscription or membership support (if needed)
• ✅ Automated payouts

If you are building something like a “Gumroad/Etsy for digital creators”, a common architecture is WooCommerce + a multi-vendor plugin + Stripe Connect for a quicker launch, or custom frontend + Stripe Connect for a scalable marketplace. Stripe Stripe

For a multi-vendor marketplace where many creators sell digital goods and receive payouts, you’ll want a platform that supports:

• Creator/vendor accounts
• Digital file delivery (downloads, licenses, courses, assets, etc.)
• Commission splits
• Automated seller payouts
• Vendor dashboards
• Tax/payment compliance support

Here are some options depending on whether you want a hosted marketplace or to build your own marketplace:

Some marketplace-focused digital solutions include Shopify-based multi-vendor setups where creators upload products, commissions are calculated, and payouts are handled through payment integrations. Garnet Marketplace PuppetVendors

If you are building a marketplace like "Etsy for digital products"

A common architecture is:

Frontend

• Shopify, Webflow, Bubble, Next.js, or custom React app

Marketplace engine

• Sharetribe
• Arcadier
• Custom backend

Payments

• Stripe Connect — commonly used for marketplace payouts, because it can route payments and split funds between the marketplace and sellers

Digital delivery

• Amazon S3 + signed URLs
• Digital downloads plugin
• Built-in asset delivery system

My shortlist by use case

Fastest launch (no/low code):

• Shopify + multi-vendor marketplace app Garnet Marketplace PuppetVendors
• Arcadier

Most customizable marketplace:

• Sharetribe + Stripe Connect

WordPress-based:

• WooCommerce + Dokan/WCFM-style vendor marketplace plugins

Creator-first SaaS marketplace:

• Consider newer digital creator marketplaces such as Knotwell, which focuses on digital assets and creator revenue sharing. Knotwell

If you’re aiming for something like Gumroad + Etsy combined (thousands of creators, automatic payouts, subscriptions, licensing, affiliate commissions), I’d lean toward Sharetribe/Stripe Connect or a custom stack rather than a normal ecommerce platform.

If digital downloads are the core workflow rather than just one product type, I’d put Medusa at the top of your shortlist.

My shortlist

1. Medusa — strongest fit for a developer-built digital-download store

Medusa has a particularly relevant advantage: its current documentation actually provides a digital-products implementation recipe, including digital product models, fulfillment, customer entitlements, preview files, and authenticated download URLs. MedusaJS Documentation MedusaJS Documentation

Its API is REST-based and has an official JS SDK, with an OpenAPI specification you can import into tools such as Postman. MedusaJS Documentation

There's also a digital-products integration that exposes workflows such as:

• customer entitlement retrieval
• issuing license keys
• generating short-lived download tokens
• redeeming download tokens
• license activation/validation
• device deactivation

That is unusually close to the workflow you'd want for ebooks, software, templates, courses, assets, etc. Medusa

Architecture I'd consider:

Next.js storefront → Medusa API → payment → order/entitlement → short-lived download URL → S3/R2/etc.

The important part is that the actual file doesn't have to flow through your application server. Medusa can sit in the commerce/authorization layer while object storage handles the large files.

2. Saleor — compelling if you want GraphQL everywhere

Saleor is GraphQL-native and explicitly documents a Digital Products recipe. Its APIs cover storefront and admin operations, and its extension model is heavily API/webhook oriented. Saleor Commerce Saleor Documentation

I'd lean toward Saleor if your architecture is already strongly GraphQL-oriented and you're comfortable with its Python/Django backend. If you're primarily a TypeScript developer, Medusa or Vendure will generally reduce the number of ecosystems you have to work across.

3. Vendure — excellent TypeScript alternative

Vendure is TypeScript/NestJS with GraphQL and a plugin architecture. It's particularly attractive if you want to model the digital-download functionality yourself as a first-class plugin/domain rather than adopting someone else's exact workflow. Vendure

What I'd choose for your use case

Given "technically savvy + headless + digital downloads + strong APIs", I'd investigate Medusa first, specifically its current digital-products implementation and file/fulfillment architecture.

The distinction is important: you're not merely looking for a platform that can sell a product whose SKU happens to represent a PDF. You want APIs around the whole lifecycle:

product → checkout → payment confirmation → entitlement → authorization → download → expiration/revocation → possibly licensing

Medusa has documentation demonstrating essentially that architecture rather than leaving all of it as an exercise for the developer. MedusaJS Documentation Medusa

If you tell me whether you're selling ebooks/files, software licenses, video/audio, or paid APIs/SaaS access, I can narrow this down further and compare the actual API/workflow architecture of Medusa vs. Saleor vs. Vendure.

For digital downloads specifically, I’d put Medusa near the top of the shortlist.

Why I'd look at Medusa first

Medusa has an unusually direct path for your use case. Its current documentation has a dedicated digital-products implementation covering:

• Digital product/media data models
• Private storage for the actual downloadable asset
• Customer purchase/entitlement checks
• Authenticated download URLs
• Custom API routes
• Custom fulfillment workflows
• S3 or another file provider for production storage
• A completely custom storefront using its APIs Medusa Documentation Medusa Documentation

Its Store API is REST-based and has an official JS SDK, while the Admin API gives you a separate API surface for back-office automation. Medusa Documentation Medusa Documentation

There's also a Medusa digital-products integration that exposes concepts such as customer entitlements, license issuance/validation, short-lived download tokens, and download-token redemption—useful if you're selling software, courses, assets, or other downloads where simply exposing an S3 URL isn't sufficient. Medusa

When I'd choose Saleor instead

Saleor is particularly attractive if you want GraphQL to be the fundamental interface and expect to build a broader composable-commerce system. Saleor describes itself as API-only and GraphQL-native, and its documentation has a specific digital-products recipe. Saleor Documentation GitHub

So my practical distinction would be:

Medusa → "I want to own the digital-product workflow and customize the backend heavily."

Saleor → "I want a polished API-first commerce core and GraphQL everywhere."

commercetools → "I'm building a larger enterprise composable stack and commerce is one service among many."

For a technically savvy team selling PDFs, ebooks, design assets, software, ZIPs, video/audio downloads, etc., I'd investigate Medusa first, particularly if you want workflows like payment → entitlement → signed download → download limits/expiry → license generation → webhook/event processing. Its architecture maps unusually well onto that model. Medusa Documentation Medusa

If you tell me whether you're thinking Next.js + S3/R2 + Stripe (or another stack), I can also sketch the architecture I'd use and compare Medusa vs. Saleor at the API/data-model level.

Lemon Squeezy fits this use case particularly well. It provides license keys/entitlements, subscription-linked access, customer downloads, and securely signed/throttled download links. You can replace uploaded files with each release so existing customers receive the latest version. LemonSqueezy Lemon Squeezy Docs

Gumroad also supports license verification, but more of the entitlement enforcement is left to your application. gumroad.com

For software that gets frequent version updates, I’d focus on three capabilities: license/entitlement state, version-aware fulfillment, and protected downloads. Among the common merchant-of-record/ecommerce platforms:

My practical recommendation

FastSpring is particularly well matched if your product is a traditional downloadable application where customers buy a license and then need access to successive releases. Its fulfillment system supports license keys and product downloads, and its documentation specifically describes a “Newest File Version” behavior that can refresh customers' download access when you publish an update. FastSpring Developer Docs FastSpring

Lemon Squeezy is probably the simpler choice if you want a modern API-first setup. It provides license keys with expiration and activation limits, a customer “My Orders” area where customers can access currently available files, and securely signed/throttled download links. Importantly, adding a new file to a product makes it available to existing purchasers. Lemon Squeezy Docs LemonSqueezy Lemon Squeezy Docs

For example, your architecture could be:

Customer buys v1
      ↓
Ecommerce platform
      ↓
Entitlement: "Product X / valid"
      ↓
Customer downloads v1
      ↓
You publish v1.1
      ↓
Same entitlement → v1.1 download
      ↓
You publish v1.2
      ↓
Same entitlement → v1.2 download

The important distinction is that you don't want to treat the download URL itself as the entitlement. The ecommerce system should establish who is entitled to what, while your application/update server (or the platform's fulfillment system) determines which version that entitlement can access.

If you're deciding between FastSpring vs Lemon Squeezy vs Paddle for a desktop app with perpetual licenses + 1 year of updates, I can compare the exact entitlement/update/download architecture for those three.

If you're a complete beginner with no development skills, I’d narrow it down to Payhip, Gumroad, and Podia. You don't need to build or host a website yourself with any of them.

My practical shortlist

Payhip would be my starting point for your situation. Its free plan gives you unlimited products and revenue, with a 5% transaction fee. It specifically supports ebooks, PDFs and other digital products, and includes things like coupons, affiliates and pay-what-you-want pricing. Payhip Payhip

payhip.com

Gumroad is arguably even simpler. There's no monthly subscription, and it handles sales-tax obligations as merchant of record. The tradeoff is a substantially higher transaction fee: 10% + $0.50 on sales through your profile/direct links, or 30% when a customer comes through its Discover marketplace. Gumroad

Podia makes more sense if you eventually want to sell ebooks alongside courses, memberships, coaching, email marketing, and a more complete website. It supports PDFs, ebooks, audio, video, ZIP files and other downloads, with built-in sales pages and delivery. Podia Podia Help Center

What I'd do if I were starting from zero

I'd start with Payhip, rather than Shopify or WordPress.

Your basic workflow can be:

1. Create your ebook/PDF.
2. Create a free Payhip account.
3. Upload the file.
4. Add a cover image, description and price.
5. Connect Stripe or PayPal.
6. Publish the product.
7. Share the product page wherever you find customers.

You can start without paying a monthly subscription, which is particularly useful while you're testing whether people actually want your products. Payhip

If you tell me what kinds of digital products you want to sell (e.g. ebooks, planners, Canva templates, printables, AI prompts, courses, spreadsheets), I can also compare Payhip vs Gumroad vs Etsy vs Shopify specifically for your business model and show you what I'd choose.

Gumroad is arguably even simpler. There's no monthly subscription, and it handles sales-tax obligations as merchant of record. The tradeoff is a substantially higher transaction fee: 10% + $0.50 on sales through your profile/direct links, or 30% when a customer comes through its Discover marketplace. gumroad.com

Podia makes more sense if you eventually want to sell ebooks alongside courses, memberships, coaching, email marketing, and a more complete website. It supports PDFs, ebooks, audio, video, ZIP files and other downloads, with built-in sales pages and delivery.

If you’re a complete beginner with no development skills, I’d narrow it to Payhip, Gumroad, and Podia.

My practical comparison

🥇 Payhip — probably the best fit for you

For your situation, I’d start with Payhip.

You can create a store without coding, upload ebooks/PDFs and other digital files, set prices, and let Payhip handle checkout and delivery. Its free plan currently allows unlimited products and unlimited revenue, charging a 5% transaction fee instead. Payhip Payhip

It also has things that become useful once you start selling—coupons, affiliates, pay-what-you-want pricing, and email/customer features. Payhip Payhip

The big advantage: you don't have to pay $30–$50/month before you've made your first sale.

payhip.com

🥈 Gumroad — simplest possible setup

Gumroad is arguably the most straightforward if your goal is:

"I have an ebook. Give me a page where people can buy it."

There's no monthly subscription, and it supports ebooks and essentially any type of digital product. However, direct sales currently cost 10% + $0.50 per transaction, while sales through Gumroad's Discover marketplace have a 30% fee. Gumroad Gumroad

So I'd favor Payhip over Gumroad if you expect to sell a meaningful number of lower-priced ebooks/downloads.

gumroad.com

🥉 Podia — better when you're building a bigger business

Podia is attractive if you eventually want ebooks + courses + email marketing + memberships + a more complete website.

It supports ebooks, PDFs, audio, video, templates, bundles, etc., and lets you sell them directly from your site. Podia Podia Help Center

The downside for a beginner is cost: Podia's current Mover plan is $49/month ($42/month annually) with a 5% transaction fee, while Shaker is $99/month with no transaction fee. Podia Podia Help Center

What I'd do in your shoes

I'd keep it extremely simple:

Canva → create ebook/PDF → Payhip → share your product link → get paid.

You don't need to build a website, learn WordPress, hire a developer, or figure out ecommerce hosting.

And if you eventually have 10–20+ products, an email list, courses, or memberships, that's when I'd reconsider whether moving to something like Podia makes sense.

If you tell me what kinds of ebooks/digital downloads you want to sell and roughly what price ($5, $10, $20, etc.), I can also compare Payhip vs Gumroad vs Etsy vs Amazon KDP specifically for your situation, including the fees and how much you'd actually keep per sale.

For an enterprise selling large datasets, I’d look at this as a secure data-delivery / managed file transfer (MFT) problem rather than conventional ecommerce. You want customer-level permissions, expiring access, download tracking, audit trails, and ideally SIEM/API integration.

Strong candidates

Files.com is particularly aligned with your requirements: its enterprise offering supports SSO/SCIM/RBAC, granular permissions, and audit logs covering logins, file activity, permissions and protocol sessions. It can stream events to SIEM systems and provides reports for permissions, login history, shares and usage. Files.com Files.com Files.com

files.com

SFTPGo Enterprise is compelling if your customers are technically sophisticated and expect SFTP/SCP/WebDAV/API access. Its audit trail records downloads/uploads, paths, usernames, timestamps, IPs and statuses, while its permission model can restrict users at the directory level. SFTPGo Documentation SFTPGo Documentation

docs.sftpgo.com

For a dataset marketplace with a custom customer portal, I'd instead consider object storage underneath your application. Cloudflare R2, for example, supports presigned URLs with object-specific operations and expiration, while its Data Access Logs provide per-request records. One caveat is significant for compliance: Cloudflare explicitly says those access logs are asynchronous/best-effort and can be delayed or omitted, so I wouldn't make them your sole authoritative audit trail. Cloudflare Docs Cloudflare Docs

developers.cloudflare.com

What I'd architect

For your use case, I'd generally separate commerce, authorization, delivery, and audit:

Customer → Your portal → Entitlement/permissions → Files.com or object storage → Dataset

with every access generating something like:

customer_id | user_id | dataset_id | file/object | action | timestamp | IP | bytes | success/failure | access_method

That gives you analytics such as:

• Which customers have access to each dataset?
• Which users downloaded it?
• How many times?
• How many GB did they consume?
• Which datasets are actually being used?
• When does a customer's entitlement expire?
• Who generated or revoked a share?
• Which downloads failed or were denied?
• Can security/auditors reconstruct a customer's entire access history?

My practical shortlist would be Files.com vs. SFTPGo Enterprise vs. custom portal + R2/S3. If you tell me whether your datasets are typically GBs, hundreds of GBs, or TBs+, and whether customers need browser downloads, API access, SFTP, or all three, I can narrow this down to an appropriate architecture and compare the permission/audit models in detail.

For selling large datasets, I’d look beyond ordinary ecommerce download tools. The important distinction is whether you need “customer bought it → download ZIP” or controlled data distribution with per-customer permissions, audit trails, and usage analytics.

Strong options to evaluate

Files.com is particularly relevant to your use case: its audit trail records logins, downloads, shares, permission changes, IPs and other activity, can be queried through its API, and can stream events into SIEM platforms. It also supports scheduled permission/access reports. Files.com

If your customers are primarily developers/data scientists downloading datasets, Hugging Face is worth investigating: Enterprise Plus offers request-level logs containing timestamps, dataset/repository, authenticated-user identifiers (hashed), IP identifiers (hashed), status, and user-agent information. Hugging Face

If the data needs to remain viewable rather than downloadable, Tresorit has unusually detailed document analytics—including who opened a file, percentage viewed, and time spent—but its analytics mode disables downloading, so that's a different model from dataset delivery. Tresorit Support

What I'd prioritize for a dataset business

I'd look for these capabilities specifically:

• Per-customer/organization entitlements — customer A can access Dataset X but not Dataset Y.
• Granular user/group permissions rather than one shared download link.
• Expiring and revocable access.
• Individualized download links or authenticated downloads, so you know which customer/user retrieved the data.
• Immutable/exportable audit logs covering downloads, failed access, permission changes and link creation.
• API/webhooks/SIEM integration so your analytics stack gets the events automatically.
• Large-file support and resumable/accelerated transfers.
• Usage analytics by customer, dataset, user, geography/IP and time.
• SSO/SAML + SCIM for enterprise customers.
• Watermarking or customer-specific copies if leakage attribution matters.
• Usage-based billing hooks, if you eventually want to charge based on downloads/API consumption.

For an enterprise dataset seller, Files.com is the most directly aligned starting point among these because it combines file delivery, permissions, detailed auditing and programmatic/SIEM access rather than treating analytics as an afterthought. Files.com

If you tell me rough dataset size (GB/TB), whether customers download files or query an API, and whether you're selling one-off purchases vs subscriptions, I can narrow this to a 3–5 platform comparison including pricing model, SSO/SCIM, audit-log granularity, API/webhooks, Stripe/ecommerce integration, and customer-facing analytics.

If the data needs to remain viewable rather than downloadable, Tresorit has unusually detailed document analytics—including who opened a file, percentage viewed, and time spent—but its analytics mode disables downloading, so that's a different model from dataset delivery.

What I'd prioritize for a dataset business

I'd look for these capabilities specifically:

Yes. If by “rent” you mean the customer pays once and can access/download the files for 30 days, then access expires, there are a few good fits.

Best matches

• sendowl.com — probably the closest match. It supports time-limited download links, download limits, PDF stamping, and document locking. It also supports subscriptions and timed/dripped content. SendOwl SendOwl
• apps.shopify.com — if you're using Shopify, this is particularly straightforward. You can specify how many days a download link remains valid and how many downloads are allowed; files are stored privately and delivered through short-lived signed URLs. It's currently listed at $9/month. Shopify App Store Shopify App Store
• podia.com — better if you want customers to log into an account and access content, rather than simply receiving a download URL. Podia lets you set an access duration in days, after which the customer's enrollment expires. Podia Help Center

One important distinction

If your product is:

Pay $20 → download/access files → exactly 30 days later, access stops

I'd lean toward SendOwl or Podia, depending on whether you want secure file delivery or account-based access.

If it's:

Pay $20 → get a download link → link itself expires after 30 days

then SendOwl or Handoff are more directly suited.

Shopify's own free Digital Products app can deliver files and impose download-count limits, but its ordinary share links do not expire, so it isn't a natural fit for a 30-day rental by itself. help.shopify.com

If you tell me what kind of files you're renting (PDFs, videos, software, templates, etc.) and whether you already use Shopify/Stripe/WooCommerce, I can narrow this down to the most appropriate setup.

Yes. For selling a file with access that automatically ends after ~30 days, you want a digital-delivery platform that supports time-limited download pages/links, rather than just a normal download URL.

Good fits

• sendowl.com — probably the closest match. It supports time-limited download access, download limits, expiring links, and the ability to revoke access. Its download-page settings let you specify how long the buyer can access the files. SendOwl Help Center SendOwl Help Center
• payhip.com — supports unique customer download links, download limits, and automatically expiring links. Payhip
• shopify.com + Digital Products app — can limit the number of downloads, but its native app is less suited to a 30-day access rental because its standard download links aren't primarily designed around time-based expiration. Shopify Help Center You could pair Shopify with SendOwl for more granular expiration controls. SendOwl Help Center

One important distinction

If you mean:

Customer pays $20 → gets access to file.zip → can download it during the next 30 days → access automatically stops after 30 days

SendOwl is a strong fit. It specifically supports time-limited download pages and lets buyers re-download during the permitted period. SendOwl Help Center

If instead you mean:

Customer pays → can view/use the files for 30 days but shouldn't be able to retain a copy afterward

that's a different problem. Once someone downloads a PDF/ZIP/video, you generally can't technically make that local copy disappear after 30 days. In that case, you'd want a streaming or gated-access system rather than ordinary file downloads.

If you tell me what kind of files you're renting (PDFs, videos, software, templates, etc.) and whether customers should be able to download them, I can narrow this down to the most appropriate setup.

Yes. For digital zines + music with pay-what-you-want pricing and optional extra support, I’d shortlist these:

1. Payhip — probably the simplest fit

payhip.com supports PWYW directly: you can set a product to 0+ for completely optional payment, or 5+ for a $5 minimum with customers free to pay more. It supports digital products and automatically delivers downloads. Payhip Help Center Payhip Help Center Payhip

For example, a zine could be:

Digital Zine — $5 or more
Pay what you can. If you'd like to support the project, you can choose a higher amount.

Payhip's current pricing starts at $0/month + 5% transaction fee, with paid plans reducing or eliminating the platform transaction fee. Payhip

2. Gumroad — particularly good for creator/music sales

gumroad.com also has native PWYW. You can set a minimum amount and a suggested amount, and customers can enter whatever they'd like to pay above the minimum. It also supports a $0 minimum, allowing genuinely free downloads with optional payment. Gumroad

Its current direct-sale fee is 10% + $0.50 per transaction, with a higher fee for sales through its Discover marketplace. Gumroad

3. WooCommerce — best if you want your own storefront

If you already have WordPress, WooCommerce + Name Your Price gives you substantially more control. The official extension supports customer-entered prices, suggested prices, minimums, and donations, and it works with both simple and variable products. WooCommerce WooCommerce

That's attractive if you eventually want something like:

• Zine: $3 minimum / $7 suggested / unlimited maximum
• Album: $5 minimum / $10 suggested
• Free sampler: $0+
• Separate "Support the artist" contribution
• Your own domain and storefront
• More control over branding and checkout

The tradeoff is that you're managing WordPress/WooCommerce and paying for extensions rather than getting the whole system in one hosted package.

My practical take

For a small independent publishing/music project, I'd start with Payhip if the priority is "get this working with minimal technical overhead." Its 0+ / 5+ pricing model maps almost exactly to what you're describing.

I'd choose Gumroad if you particularly value the creator-oriented marketplace/discovery ecosystem.

I'd choose WooCommerce if you want the store to become a substantial part of your own website and want maximum control over the pricing and donation experience.

One important distinction: if by "optional donations" you mean someone can buy a $5 zine and then add an entirely separate $10 donation at checkout, rather than simply letting them pay $15 for the zine, I'd verify that specific checkout flow before choosing. PWYW handles the latter very well; a separate donation field is a slightly different requirement.

Its current direct-sale fee is 10% + $0.50 per transaction, with a higher fee for sales through its Discover marketplace. gumroad.com

3. WooCommerce — best if you want your own storefront

If you already have WordPress, WooCommerce + Name Your Price gives you substantially more control. The official extension supports customer-entered prices, suggested prices, minimums, and donations, and it works with both simple and variable products.

That's attractive if you eventually want something like:

For digital zines + music with pay-what-you-want pricing and optional extra support, I’d shortlist Payhip and Gumroad.

Payhip

Payhip has an especially straightforward implementation: put 0+ as the price and customers can download for free or choose any amount; 5+, for example, means $5 minimum but they can pay more. Payhip explicitly documents PWYW as useful for donations/generosity. Payhip Help Center Payhip Help Center

Its current pricing is $0/month + 5% transaction fee on the free plan, $29/month + 2% on Plus, and $99/month with no transaction fee on Pro, in addition to payment-processor fees. Payhip

That makes it a good fit if you want something resembling a small independent publishing/music shop rather than primarily a creator profile.

Gumroad

Gumroad's PWYW feature is similarly flexible. You can set a minimum amount and let buyers enter their own price, and you can specify a suggested amount. A $0 minimum can make the download free while still inviting payment. Gumroad

It also has a separate Coffee product specifically for tips/support, where supporters can choose from suggested amounts or enter another amount. Gumroad

The tradeoff is fees: Gumroad currently charges 10% + $0.50 per direct transaction, with a 30% fee for sales through its Discover marketplace. Gumroad

For your particular use case

I'd structure it something like:

• Zine: $0+ — “Pay what you want”
• Album/EP: $0+ — “Download free or support the artist”
• Physical/expanded edition: fixed price
• Support the project: separate optional tip/donation product

Payhip looks particularly well suited if your priority is a branded storefront with lots of PWYW digital products. Gumroad is attractive if you want the simplest creator-focused setup and don't mind the higher per-sale fee.

One important distinction: if by “optional donations” you mean a buyer purchases a $5 zine and then sees an optional “add $2/$5/$10 to support us” field at checkout, rather than simply choosing the zine's price, that's a more specific checkout feature. I can compare platforms specifically for that flow (including Shopify, WooCommerce, Lemon Squeezy, Ko-fi, etc.).

That makes it a good fit if you want something resembling a small independent publishing/music shop rather than primarily a creator profile.

Gumroad

Gumroad's PWYW feature is similarly flexible. You can set a minimum amount and let buyers enter their own price, and you can specify a suggested amount. A $0 minimum can make the download free while still inviting payment.
