Answers that name a competitor

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 large downloadable game builds plus license/activation keys, I’d generally choose Cloudflare R2 + a small delivery API rather than a generic file-sharing service.

My recommendation

Cloudflare R2 is a particularly good fit for the file-delivery layer.

• Large files: R2 supports objects up to 5 TiB, with multipart uploads for large files and resumability. Cloudflare Docs Cloudflare Docs
• Secure downloads: Keep your builds private and generate short-lived presigned download URLs after verifying the customer's order/key. Cloudflare Docs Cloudflare Docs
• Bandwidth economics: R2 doesn't charge traditional egress/data-transfer fees, which is attractive when customers are downloading 20–100+ GB games. Cloudflare Docs Cloudflare Docs
• Easy to integrate: It's S3-compatible, so you can use standard AWS SDKs and tooling without building your own storage system. Cloudflare Docs
• No need to expose your storage: Your customer sees something like download.yourgame.com/..., while your backend controls who gets access.

The architecture I'd use

Customer purchases game
        ↓
Your store / payment system
        ↓
Order + license database
        ↓
Customer clicks "Download"
        ↓
Your API verifies entitlement
        ↓
Generate short-lived R2 signed URL
        ↓
Customer downloads directly from R2

I'd keep three things separate:

1. Build storage — R2
2. Entitlement/key management — your database/backend
3. Payment/storefront — whatever you're already using

That separation is important. A download URL should not itself be the customer's permanent license.

Security setup I'd recommend

For a paid game, I wouldn't email a permanent R2 URL.

Instead:

• Keep the R2 bucket private.
• Customer authenticates to your site or enters their order/license information.
• Your backend checks that they own the game.
• Generate a signed URL valid for, say, 15–60 minutes.
• Let the URL download the build directly from R2.
• Rate-limit requests for new URLs.
• Log downloads and flag obvious abuse.
• Give customers a way to regenerate a download link when they lose it.
• Put a SHA-256 checksum alongside each build so customers/your launcher can verify the download.
• Never put your R2/API credentials in the client or download URL generation code.

Cloudflare specifically warns that presigned URLs are effectively bearer tokens: anyone possessing one can use it until it expires, so expiration and handling matter. Cloudflare Docs

R2 vs. AWS S3

R2 would be my default for an indie studio, particularly if you're expecting lots of downloads.

AWS S3 is also an excellent choice and has essentially the same fundamental pattern: private objects + time-limited presigned URLs. AWS Documentation

I'd pick S3 instead if you're already heavily invested in AWS or want to build around AWS's broader ecosystem.

One important distinction

If by "software" you mean "I don't want to build any of this myself", then I'd look at a game-specific distribution/store platform rather than raw object storage.

If you mean "we have our own storefront and need the underlying technology to reliably deliver 50–100 GB builds", then my answer is:

Cloudflare R2 + your own entitlement API + expiring signed downloads.

That's a relatively inexpensive, scalable architecture and gives you much more control than sending customers Google Drive/Dropbox-style links.

If you tell me what you're using for the storefront/payment system (Shopify, WooCommerce, Stripe, custom, itch.io, etc.) and roughly how large your builds are, I can recommend the exact stack—including key generation, download authentication, CDN, and approximate monthly cost. developers.cloudflare.com

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 with bonus downloadable files, the ideal storefront depends on whether you want a full publishing platform, a storefront layered onto your existing site, or maximum control. The key features to prioritize are:

• Recurring billing (monthly/annual plans, failed-payment recovery)
• Member accounts and access revocation when someone cancels
• Gated file libraries (PDFs, ZIPs, templates, audio, etc.)
• Email/newsletter integration
• Subscriber ownership/export (avoid being locked into a marketplace)

Here are the strongest fits:

SendOwl MemberSpace### My shortlist by scenario

1. You are primarily a newsletter writer

• Choose Ghost if you want publishing + paid memberships in one place.
• Choose Memberful if you already have a site and want stronger membership controls.

2. Your newsletter is a funnel into a paid content vault

• Choose Podia, SendOwl, or a Shopify-based setup.
• These are better when subscribers expect a library of downloadable bonuses rather than just emails.

3. You already have a website and don’t want to rebuild

• Choose MemberSpace or Memberful.
• You can keep your existing design and add subscriber-only areas. MemberSpace MemberSpace

4. You want a branded “digital magazine + archive” storefront

• Consider newer creator commerce tools such as Fledgify, which focuses on subscriptions, digital downloads, and gated vaults. Fledgify

A practical setup I’d use for most newsletter businesses

• Newsletter + publishing: Ghost
• Payments: Stripe
• Bonus library: gated member area with files organized by month/category
• Automation: connect subscriber events to your email workflows

If your bonus files are the main reason people subscribe (for example templates, PDFs, stock assets, research archives, or downloads), I would lean toward Podia / SendOwl / Shopify + a digital membership app rather than a newsletter-only platform.

If you tell me:

1. your current newsletter platform (Substack, Mailchimp, Beehiiv, ConvertKit, Ghost, etc.),
2. whether files are PDFs vs large media files, and
3. your approximate subscriber count,

I can narrow this to the best 2–3 options.

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

For an agency managing multiple client digital-product stores, you’ll want something closer to a multi-tenant commerce platform than a normal ecommerce account. The key capabilities to look for are:

• Separate storefronts/domains per client
• Client-specific admin accounts and permissions
• White-label branding (your agency or your client’s brand)
• Central agency dashboard
• Shared infrastructure but isolated catalogs, customers, orders, analytics
• Digital delivery (files, memberships, subscriptions, licenses, courses, etc.)

Here are the strongest options by approach:

My shortlist for your use case

1. Shopify Partner ecosystem — best if you are launching many client stores

Good if each client should have their own independent store:

• Create/manage client stores through a partner workflow
• Client owns their store account
• Huge app ecosystem for digital products
• Easy handoff

Weakness:

• Not truly white-label; Shopify remains visible in admin/platform infrastructure.

2. Spree Commerce — best if you want an agency-owned platform

If your agency wants to say:

“We provide storefront infrastructure to clients”

then a multi-tenant system like Spree is closer to the model. It supports tenant stores, separate admin panels, APIs, branding, and client-specific configurations. Spree Commerce

Typical architecture:

Agency Admin
     |
     +-- Client A Store
     |      ├── Products
     |      ├── Customers
     |      ├── Orders
     |      └── Branding
     |
     +-- Client B Store
            ├── Products
            ├── Customers
            ├── Orders
            └── Branding

3. Custom headless stack — best for premium digital products

For agencies selling things like:

• courses
• templates
• memberships
• AI products
• SaaS subscriptions
• licensing

a common stack is:

• Frontend: Next.js
• Commerce backend: Medusa / Spree / custom API
• Payments: Stripe Connect
• Auth: Auth0 / Clerk / Supabase Auth
• Storage: S3-compatible storage
• Email delivery: Resend/Postmark

This gives you a true “client portal + storefront builder” product.

Platforms specifically marketing to agencies

Some newer platforms are explicitly built around agency multi-client management. For example, Sendd positions itself around agencies launching branded client marketplaces with multi-client dashboards and white-label storefronts. Sendd Store Cartvero also markets agency workflows with client shops, provisioning, roles, and white-label admin experiences. Cartvero

Recommendation by scale

• 5–20 client stores/year: Shopify Partner setup
• 20–100+ stores with repeatable templates: Spree, Medusa, or a multi-tenant custom build
• You want to sell “store infrastructure” as a service: build on a multi-tenant commerce engine
• Mostly PDFs, downloads, courses: consider a digital-product backend rather than full ecommerce

A few questions would narrow this down:

1. Are these stores selling downloads/courses/licenses, or physical products too?
2. Do clients need their own login to manage products/orders, or will your agency manage everything?
3. Are you trying to build an internal agency tool, or a SaaS product you resell to clients?

• Frontend: Next.js
• Commerce backend: Medusa / Spree / custom API
• Payments: Stripe Connect
• Auth: Auth0 / Clerk / Supabase Auth
• Storage: S3-compatible storage
• Email delivery: Resend/Postmark

This gives you a true “client portal + storefront builder” product.

Platforms specifically marketing to agencies

Some newer platforms are explicitly built around agency multi-client management. For example, Sendd positions itself around agencies launching branded client marketplaces with multi-client dashboards and white-label storefronts. Cartvero also markets agency workflows with client shops, provisioning, roles, and white-label admin experiences.

Recommendation by scale

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.

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

                    └──────────────────┘

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 limited-edition digital art, look for secure download delivery + buyer-specific watermarking, rather than full DRM (which is uncommon for art files). Good fits:

• sendowldev.com — strong DRM-lite option: expiring/single-use download links, download limits, and PDF stamping with buyer information. Good for collectible PDFs, certificates, and art books. SendOwl
• fileflare.io — good if you run a Shopify store: supports download limits, expiry, IP restrictions, and PDF stamping/watermarking. Fileflare
• help.shopify.com — simpler native option: buyer download links and configurable download limits, though less focused on watermark-style protection. Shopify Help Center

For a “1 of 100 editions” art drop, a common setup is:

1. Generate a unique file per buyer (embedded name/order ID or subtle watermark).
2. Deliver via expiring, limited-use links.
3. Include a license/certificate file tied to the purchase.

If you sell very high-value pieces, consider a custom system using unique signed URLs + per-buyer asset generation.

If you mean a platform/tool that handles per-buyer download links plus lightweight anti-sharing protection, Sellfy is a strong fit.

• Unique download link per purchase: Sellfy generates a unique link for each customer. Sellfy Sellfy
• Download limits: Each file gets up to 5 download attempts, with additional security checks if the buyer needs more. Sellfy
• Buyer-specific marking: For PDFs, Sellfy can automatically stamp the buyer's email address onto every page—useful as DRM-lite deterrence. Sellfy
• Download blocking: You can restrict downloads for individual orders and see download activity. Sellfy

Another option is Gumroad, which also provides unique download links, tracks purchaser IPs, and supports PDF stamping. Gumroad

For limited-edition digital art specifically: I'd lean toward Sellfy if your files are PDFs/images/ZIPs and you want a simple storefront with buyer-specific delivery. If you need truly expiring, signed URLs (e.g. a link that becomes invalid after 24 hours), a specialized delivery system such as ChargePanda or a custom S3/CDN setup is more appropriate. chargepanda.com

If you tell me whether your art is JPG/PNG, PDF, ZIP bundles, or video, I can recommend the best setup for preventing buyers from simply sharing the original file.

For a photographer selling high-resolution digital downloads, you’ll want more than a basic ecommerce cart. Look for:

• Low-resolution previews generated automatically from originals
• Watermarked previews while customers browse
• Clean, full-resolution delivery after purchase
• Download variants (web size, print size, original, licensing tiers, etc.)
• Gallery presentation suitable for photography
• Protection controls (passwords, disabling downloads, expiring links)

Here are strong options:

My shortlist by use case

Selling fine-art landscape, stock-style images, or commercial licenses

• PhotoDeck is one of the closest fits. It supports digital downloads, licensing models, customizable galleries, and watermarking. PhotoDeck

Selling individual images to consumers

• Pixieset or Pic-Time offer a polished buyer experience: browse, favorite, purchase, and download. Framekeep

Selling client galleries (weddings, portraits, events)

• ShootProof is built around proofing and delivery. It supports watermarks and lets you control what customers can download. ShootProof

Building your own branded store

• WordPress + a photography gallery plugin + ecommerce plugin gives the most flexibility. For example, ShutterPress supports gallery sales, watermarks, and download controls when paired with WordPress ecommerce tools. ShutterPress Gallery

Features I’d prioritize for your business model

1. Automatic preview generation

You upload the master TIFF/JPEG/RAW export once; the platform creates smaller previews.

2. Separate preview and delivery files

The preview should always be watermarked, while the purchased file should be your untouched high-res export. Platforms such as PixelPort describe this workflow explicitly. PixelPort

3. Variant pricing

Example:

• Web license — 2000px JPEG
• Print license — 6000px JPEG
• Original file — maximum resolution
• Commercial license — higher price
• Automatic fulfillment

After payment, the buyer should receive a download link without you manually sending files.

For a solo photographer primarily selling digital files (not prints), I’d usually narrow it to:

1. PhotoDeck — best photography-commerce fit
2. Pixieset — best polished customer experience
3. WordPress + WooCommerce/gallery stack — best control and long-term ownership
4. ShootProof — best if client proofing is a major part of your workflow PhotoDeck Framekeep ShootProof

If you tell me whether you’re selling stock/licensing, fine-art prints as downloads, or client galleries, I can narrow it further.

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

For a small shop owner who sells both digital products and occasional physical goods, you’ll usually want a platform that can handle:

• physical inventory + shipping labels
• digital downloads or memberships
• mixed carts (a customer buys a physical item and a digital file together)
• taxes and payments
• simple day-to-day management without lots of technical work

Here are the strongest fits:

Shopify Shopify### My practical recommendation by shop type

If physical goods are your main business and digital products are occasional:

• Choose Shopify. It is designed around commerce operations: inventory, shipping, checkout, and selling across channels. You can add digital downloads through apps when needed. Shopify

If you already have a WordPress site/blog:

• Choose WooCommerce. It gives you more control over your store and content, but you’ll spend more time managing hosting, plugins, and updates. Shopify

If your shop is more creative (art, photography, handmade goods, templates, guides):

• Choose Squarespace. It is often smoother for a polished brand site with a smaller product catalog. Shopify

If you want the simplest setup and don’t expect complex inventory:

• Wix can work well for a small mixed store. Shopify

For your specific situation (small shop + occasional physical sales)

I’d narrow it to:

1. Shopify — best overall balance of shipping + digital add-ons
2. Squarespace — best if your website/brand presentation matters more than advanced store operations
3. WooCommerce — best if you like tinkering and want maximum control

A useful question is: Are your digital products things like PDFs/templates/downloads, or are they courses, memberships, or subscriptions? That changes which platform fits best.

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 a technically savvy team selling digital downloads, I’d shortlist these:

• spreecommerce.org — strongest if you want control. It’s API-first, self-hostable, has REST APIs/OpenAPI tooling, and supports digital products, subscriptions, and custom fulfillment flows. Good fit if you’ll build your own download entitlement service. Spree Commerce Spree Commerce
• shopify.dev — best ecosystem. Its Storefront API works well for headless builds, but digital delivery usually relies on apps or your own fulfillment layer rather than a native “digital asset pipeline.” Shopify
• bigcommerce.com — strong catalog/order APIs and mature headless support; good if you want SaaS reliability and less infrastructure ownership. BigCommerce
• business.adobe.com — powerful downloadable-product workflows via REST APIs, but heavier operationally. Experience League

For a developer-centric digital download store (files, licenses, memberships, gated content), I’d lean Spree or a custom backend around Shopify/BigCommerce + object storage (S3/R2) + signed URLs. The key API features to evaluate are: webhook reliability, entitlement modeling, download limits, license-key support, refund/revocation workflows, and CDN delivery.

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 with frequent releases, look for a software licensing + entitlement platform, not a general ecommerce cart. Strong options:

• Revenera — enterprise-focused; handles licenses, entitlements, download rights, version delivery, and update eligibility. Good for commercial desktop software and complex licensing models. Revenera Revenera
• ChargePanda — built around purchase → entitlement → signed download flows, versioned files, support/update windows, and expiring download links. ChargePanda
• WooCommerce + licensing extensions — flexible if you want to own the storefront; extensions such as Kestrel API Manager add license keys, activations, secure downloads, and update APIs. WooCommerce WooCommerce
• Build-your-own with a payment provider + entitlement service — common for SaaS/dev tools: checkout creates entitlements, your API validates them, and downloads are served through signed URLs or authenticated endpoints.

Minimum architecture to aim for:

1. Order system → creates customer entitlement.
2. License/entitlement API → answers “is this customer allowed version X?”
3. Update manifest endpoint → app checks for new versions.
4. Secure download endpoint → returns short-lived signed URLs or streams files after entitlement validation.
5. Admin tooling → revoke licenses, manage versions, view downloads.

For a small-to-mid software vendor, I’d usually choose a licensing-focused solution rather than trying to make Shopify/WooCommerce alone handle update authorization. For enterprise desktop software, Revenera-style tooling is more typical; for indie apps, a lighter entitlement service is often enough. Revenera

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

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. Podia Podia Help Center

podia.com

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.

🥉 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.

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.
