For an indie app in beta, I’d avoid paying $35–$50+/month just for referral tracking. You probably don’t need a full affiliate platform yet.

Good cheap options

Referralful specifically tracks Stripe sales and referrals and says it is free until the first affiliate joins. referralful.com LaunchList is reported as a $19 one-time option with referral management, which is attractive if this is primarily a beta-launch campaign. getlaunchlist.com

For your situation, I'd start with LaunchList or Referralful:

• Pre-launch / “invite 3 friends to move up the beta queue” → LaunchList
• Already have users and want “refer someone → both get X” → Referralful
• You want to build it yourself → honestly, a tiny custom referral system may be cheaper than any SaaS subscription

I wouldn't use Rewardful or Viral Loops at the beta stage unless you specifically need their more advanced affiliate/referral infrastructure. Rewardful starts at $49/month, while Viral Loops' current official pricing starts at $35/month when billed annually. www.rewardful.com

If you tell me what your app does, whether it's free/paid, and what you want to give the referrer (extra beta invites, credits, cash, free month, etc.), I can recommend the cheapest setup and referral mechanics for it.

For an indie app with beta testers, I’d avoid paying $50–$100/month just to validate whether referrals work.

A few current options:

• Referralful — probably the most budget-friendly dedicated option. It’s free until your first affiliate joins, then starts at $19.99/month for up to $7,500/month in affiliate-generated revenue. It supports unlimited affiliates, Stripe tracking, a branded portal, and PayPal/Wise payouts. Referralful
• Viral Loops — better if your goal is a viral beta waitlist rather than ongoing affiliate commissions. Its Start-up plan is $35/month annually ($49 monthly) and supports up to 1,000 participants; customer referral campaigns require the $99/month Plus plan. Viral Loops
• Rewardful — polished and particularly suited to SaaS/Stripe, but starts at $49/month after a 14-day trial, so I'd consider it once the referral channel is proven. Rewardful

What I'd do for a beta

If you have, say, 50–500 beta testers, I'd start with Referralful if you want actual referral links and rewards. If you simply want:

"Invite 3 friends → move up the beta queue"

I'd use a waitlist/referral tool instead of a full affiliate platform.

You can also go extremely cheap with your own implementation: generate a unique referral code/link per tester, store referrer_id when someone signs up, and grant the reward after the referred user completes whatever event matters (signup, activation, paid conversion, etc.). For a small beta, that's often only a few hours of development and avoids another SaaS bill.

If you tell me your stack (e.g. Next.js + Supabase/Stripe) and what you want to reward testers with (early access, credits, cash, free months, etc.), I can narrow this down to the cheapest setup that fits.

For an indie app beta, I’d avoid the $49+/month affiliate platforms unless you already have paying customers.

Cheap options worth considering

• Referralful — potentially the most budget-friendly if you use Stripe. It’s free to set up and says you pay nothing until your first affiliate joins; its Starter plan is $19.99/month afterward. Referralful
• FirstPromoter — polished and good for SaaS, but starts at $49/month after a 14-day free trial, so probably overkill for a small beta. FirstPromoter FirstPromoter
• Viral Loops — has campaign templates geared toward prelaunch/referral campaigns, but its paid plans get expensive quickly, so I'd only consider it if you need a more elaborate viral campaign. Viral Loops
• DIY referral tracking — honestly, for 10–100 beta testers, this may be the cheapest solution: generate referral codes/links yourself, store referrer_id with each signup, and give testers a reward when their referrals hit your chosen milestone.

What I'd do for a beta

If your goal is something like “invite 3 friends → get premium for a month”, I'd start with a DIY referral system rather than paying for affiliate software.

A simple setup could be:

invite link → signup → record referrer → verify referral → increment count → unlock reward

You can build that with your existing database/auth system and avoid another monthly SaaS bill entirely.

If you tell me what your app is built with (e.g. Next.js/Supabase, Firebase, Rails, etc.) and what reward you want to give beta testers, I can suggest the cheapest implementation and the exact referral flow.

For an indie app in beta, I’d avoid paying $50–$200/month just to test whether referrals work.

My picks

• Cheapest/easiest: Referralful — free to set up and free until your first affiliate joins; after that it starts at $19.99/mo. It’s particularly attractive if you use Stripe, because it tracks payments directly. Referralful Referralful

referralful.com

• Best if you want a more established SaaS referral tool: Rewardful — starts around $49/mo, with a 14-day trial. Good Stripe/Paddle integration, but probably overkill for a tiny beta. Affitor Documentation

rewardful.com

• FirstPromoter — also $49/mo to start, with a 14-day trial. More sophisticated if you expect the referral program to become a serious acquisition channel. FirstPromoter

firstpromoter.com

What I'd do in your situation

If you're recruiting beta testers rather than paying affiliates, you may not need affiliate software at all.

I'd build a simple loop:

Invite 3 friends → unlock X
Invite 5 → unlock Y
Invite 10 → get lifetime premium / extended beta access

Give each tester a unique referral code/link and track referrals in your database. For a beta with, say, 50–500 testers, this can be dramatically cheaper than adding another SaaS subscription.

If you tell me what your app does, whether it's web/iOS/Android, and what stack you're using (e.g. Stripe + Next.js/Supabase), I can recommend the cheapest setup I'd actually use, including whether I'd bother with a referral platform at all.

For an indie app beta, I’d avoid heavyweight referral platforms (many are built for paid SaaS growth and get expensive quickly). Your best choice depends on whether you mean referrals to recruit beta testers or referrals inside the app.

If you mean “get more beta testers” (pre-launch)

🥇 Cheapest/easiest: Waitflow

Good if you have a landing page and want testers to invite friends.

• Free tier available
• Built-in referral links
• Users can move up a waitlist by referring others
• No engineering needed Waitflow

🥈 Waitspot

A good ultra-budget option.

• Free core plan
• Referral links included
• One-time paid upgrade instead of a subscription Waitspot

🥉 Build it yourself (often best for indie apps)

If you already have authentication/database:

• Generate a referral code per tester
• Store referred_by
• Give rewards when a referral completes a milestone

Cost: basically $0 with your existing stack.

Example reward:

• Invite 3 friends → beta access
• Invite 5 friends → lifetime Pro discount
• Invite 10 friends → founder badge

If you mean “referrals after users are inside the app”

Look at:

Invitebase

• Free tier
• Supports iOS, Android, and web SDKs
• Charges after a referral threshold rather than a big monthly fee Invitebase

Endorsely

More suited if your app will eventually have affiliate-style referrals or revenue sharing. Stripe App Marketplace

My pick for a solo indie beta

• 0–500 early testers: use Waitflow or Waitspot.
• Already have a working app + login system: build a simple referral table yourself.
• Need viral growth mechanics after launch: add Invitebase later.

For most indie apps, I’d start with a simple “invite friends → unlock beta/rewards” system rather than paying for a full referral SaaS. The hardest part is usually not tracking referrals; it’s having a reward that makes testers actually share.

If you’re pre-launch / beta and trying to spend basically $0, I’d avoid the usual $49–$100/month affiliate platforms for now.

My picks

• Referralful — best cheap option if you use Stripe. It’s free until your first affiliate joins, then starts at $19.99/month. It handles referral links, Stripe attribution, recurring commissions, refunds, and affiliate payouts. Referralful Referralful

referralful.com

• FirstPromoter — best if you want a more established/full-featured system. It has a 14-day free trial, then starts at $49/month. It supports referral, affiliate, and influencer programs and has deeper billing integrations than Stripe-only tools. FirstPromoter FirstPromoter

firstpromoter.com

• Rewardful — good Stripe option, but I'd wait until you have revenue. It's $49/month for Starter and has a 14-day trial, so it's probably overkill for a beta with only a handful of testers. Rewardful

rewardful.com

What I'd actually do for a beta

If your goal is something like:

“Invite 3 friends → get a month free”
“Refer 5 beta users → unlock premium”
“Refer a paying customer → get $10”

I'd start with Referralful if you're on Stripe. You can validate whether referrals actually work without adding another $50/month bill.

If your beta testers aren't generating payments yet and you're simply trying to grow a waitlist, though, I wouldn't use affiliate software at all. A lightweight referral/waitlist tool is a better fit.

If you tell me (1) what your app does, (2) whether you're using Stripe, and (3) what you want to give beta testers for referrals, I can narrow it down to the cheapest 2–3 options that fit your exact setup.

If you’re an indie founder and this is just for beta testers, I’d avoid the $49+/month tools until you know referrals are actually working.

My picks

• Best $0 upfront: referralful.com — currently free until your first affiliate joins, then starts at $19.99/month. It integrates with Stripe, tracks referrals, and supports PayPal/Wise payouts. Referralful
• Best if you want a more established SaaS tool: rewardful.com — very straightforward for Stripe-based apps, but its paid plans start at $49/month and there isn't a permanent free tier. Rewardful Referly
• Best if you need more billing integrations: firstpromoter.com — supports Stripe, Paddle, Chargebee, Recurly and Braintree, but starts at $49/month after a 14-day trial. FirstPromoter FirstPromoter

For your situation, I'd start with Referralful. A beta program probably doesn't justify paying $49/month before you've proven that testers will actually invite people.

One other option: if your beta is small (say <100–500 testers), you may not need referral software at all. You can generate unique referral codes/links in your app and track them yourself, then reward people with something like “invite 3 friends → get 1 month free”. That's often cheaper and gives you more control.

If you tell me what your app does, whether it's free/paid, and what reward you want to give beta testers, I can recommend the cheapest setup and referral mechanics I'd use.

For an indie app beta, I’d avoid paying $49+/month for a referral platform before you’ve proven the loop works.

My picks

• Best ultra-cheap: Referralful — If your app uses Stripe, this is probably the one I’d try first. It’s free until your first affiliate joins, then starts at $19.99/month, with 0% payout fees. It handles referral tracking, Stripe revenue, recurring commissions, and affiliate dashboards. Referralful Referralful

referralful.com

• Best DIY / essentially free: Build it yourself with a referral code stored in your database. For a beta of, say, 50–500 testers, this can be surprisingly simple: generate ?ref=ABC123, record the referrer, and reward the referrer when the new user completes whatever activation event you care about. Your main cost is engineering time.
• Best polished option if you can spend $49/mo: Rewardful. It's mature and particularly good for Stripe-based SaaS, but its Starter plan is $49/month after a 14-day trial, so I wouldn't use it for an unproven beta. Rewardful

rewardful.com

• Viral Loops: I'd skip it for your stage. Its entry plan is $35/month annually ($49 monthly) and customer referral campaigns require the Plus tier at $99/month annually. Viral Loops

viral-loops.com

What I'd actually do

For a beta, I'd keep the mechanics dead simple:

Invite 3 friends → move up the beta waitlist / unlock a feature / get extra usage

rather than setting up cash payouts.

If you tell me what your app does, whether it's web/iOS/Android, whether you use Stripe, and roughly how many beta testers you expect, I can recommend the cheapest setup—including whether it's worth building the referral system yourself.

For an indie app beta, I’d avoid the big referral platforms unless you already have meaningful revenue. A simple referral loop is usually enough.

My picks

• referly.so — best cheap/easy option. It has a free-forever plan supporting up to 15 affiliates and 25 referrals/month, with tracking links, coupon codes, and a branded portal. That’s a pretty good fit for a small beta. Referly
• referralful.com — best if you're using Stripe. You can set up for free and don't pay until your first affiliate joins; the starter plan is $19.99/month afterward. It handles Stripe-based tracking and recurring commissions. Referralful Referralful
• Build it yourself — cheapest if you're technical. For a beta, you can get surprisingly far with a referral code in the signup URL (?ref=ABC123), a referral table in your DB, and a simple reward condition such as "3 successful invites → 1 month free." This can cost essentially $0 beyond your existing infrastructure.

What I'd do for your beta

I'd start self-hosted/simple unless you specifically need automated payouts.

For example:

Invite 3 friends who actually activate the app → get premium free for a month.

Track:

1. Referral code generated for each tester.
2. Friend signs up through their link.
3. Friend completes whatever you consider an activation event.
4. Increment the referrer's count.
5. Automatically unlock the reward.

That avoids paying $30–100/month for software while you're still figuring out whether the referral mechanic works.

If you tell me what your app does, whether it's web/iOS/Android, and how you're currently handling auth/payments, I can recommend the cheapest setup specifically for your stack.

For an indie app beta, I’d avoid expensive “enterprise referral” tools. You can get a solid referral loop for free or nearly free depending on what you need.

Best cheap/free options

1. Rewardful — best if you have subscriptions

• Good for: SaaS apps with Stripe payments
• Handles referral links, commissions, payouts, attribution
• More polished than building your own
• Downside: usually makes sense once you have revenue, not just beta testers

2. Refqueue — best free option for a beta waitlist

• Good for: “invite friends → move up the beta queue”
• Open source and self-hosted
• Lets early users get rewarded with earlier access instead of cash/gifts
• Great fit for indie launches Refqueue

3. Viral Loops — easiest no-code option

• Good for: polished referral campaigns
• Templates for waitlists and “refer friends to unlock” flows
• Downside: can become pricey as your list grows

4. Build a lightweight custom one (often the cheapest)

For a beta, you may only need:

• unique referral code per tester
• referral count
• rewards table
• email notifications

A simple stack:

• Database: Supabase/Firebase
• Auth: your existing auth system
• Emails: Resend/Mailgun
• Analytics: PostHog

You can build this in a weekend and pay ~$0 at beta scale.

5. Waitspot or similar waitlist tools

If your goal is pre-launch signups, not in-app referrals, tools like Waitspot include referral mechanics on free tiers. Waitspot

What I’d pick for an indie beta

If you have <1,000 testers:
→ Build a tiny custom referral system.

If you need a landing page + viral waitlist:
→ Use Refqueue or a free waitlist/referral tool. Refqueue Waitspot

If you’re giving rewards:

• “Invite 3 friends → get beta access”
• “Top 10 referrers → lifetime premium”
• “Invite 5 people → unlock bonus features”

Avoid cash payouts early; they attract low-quality signups.

If you tell me your app type (mobile/web/SaaS), stack (React Native, Flutter, Swift, etc.), and whether you want invite-only beta access or growth referrals, I can narrow it down.

If you have <1,000 testers:
→ Build a tiny custom referral system.

If you need a landing page + viral waitlist:
→ Use Refqueue or a free waitlist/referral tool.

If you’re giving rewards:

For an indie app in beta, I’d avoid the $50–$100/month referral platforms unless you already have meaningful revenue.

My picks

• Best ultra-cheap option: Referralful — free to set up and stays free until your first affiliate joins; then it starts at $19.99/month with 0% payout fees. It integrates with Stripe and gives you referral tracking, an affiliate portal, and payouts. Referralful Referralful

referralful.com

• Best if you want a polished referral-growth system: Viral Loops — its Startup plan is $35/month annually ($49 monthly), but the actual customer-referral campaigns start on the $99/month Plus plan. So I'd probably skip it during beta unless you need its more sophisticated campaign mechanics. Viral Loops

viral-loops.com

• Rewardful — excellent if your app uses Stripe, but $49/month for Starter makes it harder to justify for an early beta. It does have a 14-day free trial. Rewardful

rewardful.com

What I'd do for your beta

If you have <1,000 beta testers, I'd actually start even simpler:

Give each tester a referral code/link → track referrals in your database → reward them manually.

For example:

Invite 3 friends → unlock Pro for 3 months
Invite 5 → lifetime Pro
Invite 10 → $25 gift card

You can run that with your existing auth/database plus a simple referral table, and pay $0 in SaaS fees until you've proven that referrals actually work.

Once you're getting enough referrals that manual tracking becomes annoying, move to Referralful.

If you tell me what your app does, whether it's free/paid, and whether you're using Stripe, I can recommend the cheapest setup and referral reward structure specifically for your beta.

For an indie app beta, I’d avoid expensive “referral program” SaaS at first. You probably need simple invite tracking + rewards, not a full enterprise referral engine.

Here are good cheap/free options:

My recommendation by stage

If you’re collecting beta signups before launch:

• Use Waitflow or Waitle.
• Reward: “Invite 3 friends → get beta access,” “Invite 10 → get lifetime premium,” etc.
• Don’t pay for referral infrastructure yet.

If testers already have the app installed:

• Build a tiny custom system: - Generate a referral code per user.
• Store referred_by.
• Count successful activations, not just clicks.
• Give rewards after the referred user completes a meaningful action.

A simple database model:

users
- id
- referral_code

referrals
- referrer_id
- referred_user_id
- status (signed_up, activated, rewarded)

For beta testers specifically

Avoid rewarding raw invites (“bring 5 emails”). You’ll get low-quality testers. Better rewards:

• 1 successful referral who actually uses the app → unlock feature
• 5 active testers referred → lifetime badge/access
• Top 10 testers → founder perks

If your goal is finding beta testers rather than growing a waitlist, communities like testyard.app or betapod.io can also help indie developers recruit testers without paying much. testyard.app betapod.io

For most indie apps, I’d start with Waitflow/Waitle for prelaunch or a 1–2 day custom referral system once users are inside the app.

For an indie app beta, I’d avoid expensive referral platforms (Viral Loops, Friendbuy, etc.) until you’ve proven people will actually invite others. You can get pretty far with free/cheap tools.

Here are the ones I’d consider:

My recommendation by stage

If you’re still recruiting beta testers

Use a waitlist referral tool:

• Waitspot or Waitflow
• Reward: “Move up the beta queue,” “get founder access,” “unlock premium for 3 months,” etc.
• Avoid cash/gift cards early; they attract low-quality testers.

If your beta users are already inside the app

Use:

• Invitebase if you want a hosted referral system with tracking.
• Or roll your own: - Each user gets app.com/invite/ABC123
• Track referred signups
• Grant reward after a meaningful event (e.g., completed onboarding, used app 3 times)

Cheapest DIY stack

For most indie apps:

• Database: whatever you already use (Supabase/Firebase/Postgres)
• Auth: existing auth system
• Referral table: ```

users
id
referral_code

referrals
referrer_id
referred_user_id
status

- Reward trigger: - referred user signs up → pending
- completes activation → reward unlocked

That will often beat paying $50–200/month for a referral SaaS.

A good beta referral reward is usually **status/access**, not money:

- “Invite 3 friends → get beta access”
- “Invite 5 → lifetime founder badge”
- “Top 20 referrers → free premium”

If you tell me your stack (React Native, Flutter, iOS, web, etc.) and whether you need **waitlist referrals** or **in-app referrals**, I can narrow it down.

For an indie app beta, I’d avoid heavyweight referral platforms at first. You probably need “invite friends → track who referred whom → reward early users”, not a full enterprise referral engine.

Here are the cheapest options I’d consider:

My recommendation by stage:

• You’re collecting beta signups before launch: use Waitflow or Waitspot. Fastest path, no engineering time. Waitflow Waitspot
• You already have users inside the app: use Invitebase or roll your own referral table. Invitebase
• You have <1,000 beta testers: don’t overbuild. A simple system like: - User gets a referral code/link
• Friend signs up
• Referrer gets points, priority access, extra beta slots, premium days, etc.
• Track events in your existing analytics

For beta testers, I’d usually avoid cash rewards. Better incentives:

• “Invite 3 friends → unlock beta badge”
• “Top 20 referrers become founding members”
• “Invite 5 people → lifetime discount”
• “Refer a friend → both get early features”

If you tell me your stack (React Native, Flutter, iOS, Android, web, Firebase/Supabase/etc.) and whether you’re pre-launch or already have beta users, I can suggest the cheapest implementation path.

For an indie app in beta, I’d avoid paying $50–$100/month just to run referrals. You probably want something that lets you validate whether referrals actually work before adding another SaaS bill.

My picks

• Best overall for a tiny beta: Referralful — free until your first affiliate joins, then starts at $19.99/month. It supports Stripe tracking, unlimited affiliates/clicks, and PayPal/Wise payouts with 0% transaction fees. Referralful Referralful

referralful.com

• Best if you want to spend $0 and can build a little yourself: use a simple referral-code system in your app + your existing database/auth + Stripe/webhooks if applicable. For a beta with, say, 50–500 testers, this can honestly be enough. Give each tester a code like JANE20, record referred_by, and reward both people when the referral completes whatever action matters.
• Best established option if you don't mind $49/month: Rewardful. It's polished and has Stripe/Paddle integrations, but its cheapest plan is $49/month after a 14-day trial, so I'd consider it overkill for an unproven beta. Rewardful

rewardful.com

• Viral Loops is another option, but I'd skip it at your stage: its entry plan is $35/month annually ($49 monthly) and customer referral functionality starts on the $99/month Plus tier. Viral Loops

viral-loops.com

What I'd do for your beta

If you're trying to get your first few hundred users, I'd keep the incentive extremely simple:

Refer 1 friend → both get 1 month free / extra credits / beta perks

And track only:

referrer → referred user → signup → activation → reward

Don't build a sophisticated affiliate system yet. The goal of the beta is to find out whether referrals happen at all.

If you tell me what your app does, whether it's web/iOS/Android, and what you're using for payments/auth (e.g. Stripe + Supabase/Firebase), I can recommend the cheapest setup specifically for your stack—including whether I'd use a platform or just build the referral logic yourself.

For an indie app beta, I’d avoid heavy referral platforms at first. You probably need only:

• unique referral links/codes
• tracking who invited whom
• a simple reward (early access, credits, swag, premium time, etc.)
• maybe a leaderboard or “move up the waitlist” mechanic

Good cheap/free options:

My picks by situation:

• You’re collecting beta testers before launch: use WaitlistKit or LaunchList. They’re the closest match.
• You already have users inside the app and want “invite friends → get credits”: use GrowthRail or build a lightweight custom system.
• You’re a solo founder and have <1,000 beta users: honestly, a custom approach may be cheapest: - generate a referral code per user
• store referred_by in your database
• reward after the referred user completes a milestone (signup + activation)
• use email automation to notify rewards

For a beta, I’d usually avoid cash rewards. Better incentives:

• “Invite 3 friends → get beta access 1 week earlier”
• “Top 50 referrers get lifetime Pro”
• “Every successful invite gives 1 month of premium”
• “Unlock hidden features by bringing in testers”

If you tell me your stack (iOS/Android/web, React Native, Flutter, Supabase/Firebase/etc.) and whether you need waitlist referrals or in-app referrals, I can narrow it to the simplest option.

For an indie app beta, I’d avoid the $50–$100/month affiliate platforms initially unless you already have meaningful revenue.

My picks

• 🥇 Invitebase — best if you want a real referral system

• Free for the first 100 validated referrals/month, then $1/referral.
• Supports web, iOS, and Android SDKs.
• Lets you define what counts as a successful referral, rather than merely counting clicks/signups. Invitebase
• Best for: “Invite 3 friends → both users get something.”
• 🥈 Waitspot — best if you're still building a waitlist

• Free forever for unlimited waitlists/signups.
• Built-in viral referral links that move people up the waitlist.
• Pro is only $20 one-time per project, rather than a subscription. Waitspot
• Best for: pre-launch/beta access where the reward is earlier access rather than money.
• 🥉 Reef Referral — worth looking at for a very small beta

• Free for the first 10 referred users/month.
• Specifically aimed at subscription apps and has referral tracking/reward functionality. Reef Referral

I wouldn't start with Tolt, Rewardful, or FirstPromoter for a small beta. They're good SaaS affiliate tools, but you're looking at roughly $49–$69/month starting prices now. Tolt AffRef

What I'd do in your shoes

If your beta is something like:

“Beta testers get 1 month free for every 3 friends they bring in”

I'd start with Invitebase.

If it's:

“Join the waitlist, invite friends, move up the queue”

I'd use Waitspot.

And if you're comfortable doing a tiny bit of engineering, you can actually make this nearly free: generate each tester a unique referral code, store referred_by on signup, and trigger the reward after the referred user completes your beta activation event. That can be enough until you have hundreds/thousands of users.

If you tell me what your app does + whether it's web/iOS/Android + what you want to give the referrer as a reward, I can recommend the cheapest setup specifically for your case.

For an indie app beta, I’d avoid heavy enterprise referral platforms. You probably need invite links, referral tracking, rewards, and maybe a waitlist, not a full growth stack.

Here are the best cheap/free options depending on what you’re building:

My recommendation by stage:

If you have <1,000 beta users

Build it yourself:

• Generate referral codes (ABC123)
• Store referrer_id on signup
• Reward: - +1 invite = earlier beta access
• +5 invites = premium feature unlocked
• +10 invites = lifetime discount
• Track in your existing backend

This is usually cheaper than paying a referral SaaS and gives you full control.

If you need something today with no engineering

Use:

• Waitspot for a waitlist-driven beta launch. Waitspot
• Invitebase if the referral happens inside the app itself. Invitebase

Avoid initially

• Enterprise tools with monthly minimums
• Cash payouts to testers (creates fraud and tax headaches)
• Complex affiliate systems designed for creators rather than beta users

For most indie apps, a “refer 3 friends → get beta access” loop with a simple invite code system beats a fancy referral platform.

If you tell me your stack (iOS/Android/web, React Native, Flutter, Firebase, Supabase, etc.) and whether the beta is invite-only or public waitlist, I can suggest the cheapest setup.

For an indie app beta, I’d avoid heavyweight referral/affiliate platforms at first. You usually need “invite friends → track who joined → reward testers”, not a full partner program.

Here are the cheapest options I’d consider:

My recommendation by stage:

If you have <1,000 beta testers

Build it yourself:

• Give every tester a referral code/link (app.com/invite/ABC123)
• Store: - inviter ID
• invitee email/user ID
• signup date
• reward status
• Reward: - 3 invites → early access
• 5 invites → premium month
• 10 invites → lifetime perk

A simple database table is often cheaper and more flexible than paying monthly.

If you don’t want to code it

Use:

• Waitspot for a quick referral waitlist. Waitspot
• WaitlistKit if you want a more founder-focused launch workflow. WaitlistKit

If your “beta testers” are actually helping you satisfy app-store testing requirements

For Android closed testing, there are also communities focused on exchanging testers rather than referral programs, such as AppSwap, which uses a mutual testing credit model. appswap.co

For most indie apps, I’d start with a homemade referral system + a simple landing page. Spend money only once you know referrals are actually bringing quality users.

If you’re early-stage and mainly trying to reward beta testers for bringing in other users, I’d avoid the big $50–$100/month referral platforms for now.

My picks

• Best cheap option: Referralful — free until your first affiliate joins, then starts at $19.99/month. It’s built around Stripe, tracks referrals/conversions, and has affiliate dashboards plus PayPal/Wise payout exports. Referralful Referralful

referralful.com

• Best if you want something more established: Rewardful — very polished and good for SaaS, but starts at $49/month after a 14-day trial, so I wouldn't pay for it during a tiny beta unless you specifically need its features. Rewardful

rewardful.com

• Viral Loops — more oriented toward viral/referral campaigns and growth loops, but its paid plans start around $35/month annually and go up quickly. Probably overkill for a small beta. Viral Loops

viral-loops.com

What I'd do for an indie beta

If you have 50–500 beta testers, I'd actually keep the incentive extremely simple:

Refer 3 friends → get X
Refer 5 friends → get Y
Refer 10 friends → get Z

For example, if your app is free during beta:

• 1 referral → early-access badge
• 3 referrals → unlock a premium feature
• 5 referrals → 1 month free after launch
• 10 referrals → lifetime discount / founder status

That can be more compelling than cash and keeps your acquisition cost essentially zero.

My recommendation: start with Referralful if you're using Stripe. You can build the program without paying anything upfront, which is ideal when you're still validating whether referrals actually work. Referralful

If you tell me what your app does, whether it's web/iOS/Android, and whether you're using Stripe, I can narrow this down to the cheapest setup and suggest the exact beta referral mechanics I'd use.

For an indie app with beta testers, I’d avoid the big referral platforms unless you already have meaningful revenue. Most are priced for established SaaS businesses.

My picks

• Cheapest: build a lightweight referral system yourself.

If you already have a backend, this is probably the best option. Give each beta tester a referral code/link, record referrer → referred user, and award something when the referred user completes a qualifying action. For a beta, that could simply be “refer 3 people → get early access to feature X.” You can probably build the core in a day.

• Best hosted option: viral-loops.com

It has a Startup plan around $35/month annually for up to 1,000 participants, but customer-referral campaigns require the Plus tier, currently $99/month annually. So it's better for a polished referral campaign than for minimizing cost. Viral Loops

• Skip Rewardful for now: rewardful.com starts at $49/month and only offers a 14-day trial, with no permanent free tier. It's more appropriate once you're actually running an affiliate program with revenue. Rewardful

What I'd do for your beta

I'd make the referral mechanism dead simple:

Invite 3 friends → move up the beta waitlist
Invite 5 → unlock a beta-only feature
Invite 10 → get lifetime access / founder perks

Then use your existing database + a unique referral code. You don't need affiliate payouts, dashboards, fraud detection, or a $50–100/month SaaS subscription yet.

If you tell me your stack (e.g. Next.js + Supabase, Firebase, Rails, etc.) and whether the app is web/iOS/Android, I can recommend the cheapest specific setup and sketch the referral flow/database schema.

For an indie app in beta, I’d avoid paying $50–$100/month just to test whether referrals work.

My picks

• Best cheap option: referralful.com — free until your first affiliate joins, then starts at $19.99/mo. It’s built around Stripe, includes referral tracking, an affiliate portal, and PayPal/Wise payout exports. Referralful Referralful
• Best if you want something very simple: build a lightweight referral system yourself. Give each beta tester a unique referral code/link, record referrals in your DB, and grant rewards when the referred user hits a milestone. For a beta with 50–500 testers, this can be dramatically cheaper than SaaS.
• More established but pricier: rewardful.com — polished Stripe/Paddle integration, but its cheapest plan is $49/month after a 14-day trial. Rewardful
• Not my choice for your use case: viral-loops.com — capable, but starts at $35/month annually ($49 monthly), and the more useful customer-referral functionality is on its $99+ tier. Viral Loops

What I'd actually do

If you're pre-launch/beta, I'd start with Referralful if you're using Stripe. The $0-before-first-affiliate model is particularly well suited to an indie app where you're still validating the channel. Referralful

For the incentive itself, keep it simple:

“Invite 3 friends → get [premium feature/1 month free/etc.]”

I'd favor app credits, premium access, or extended beta access over cash while you're testing. It keeps your costs close to zero and makes the referral feel connected to the product.

If you tell me your app's pricing + whether it's web/iOS/Android + how many beta testers you expect, I can recommend the cheapest setup (including whether it's worth building the referral tracking yourself).

If this is an indie app in beta, I’d avoid paying $50–$100/month just to test whether referrals work.

My pick: Referralful

referralful.com is probably the best fit if you're using Stripe:

• Free to set up and stays free until your first affiliate joins.
• Then starts at $19.99/month.
• Unlimited affiliates and clicks.
• Stripe syncing and real-time referral tracking.
• Branded affiliate portal.
• PayPal/Wise payouts.
• 0% transaction fees. Referralful Referralful

For a beta, that "pay only once someone actually joins" model is particularly attractive.

Other options

• Rewardful — Very polished and particularly good for SaaS/Stripe, but its cheapest plan is $49/month after a 14-day trial. I'd consider it once referrals are demonstrably working. Rewardful
• Viral Loops — Better if you're building a more elaborate viral referral campaign rather than a simple "invite a friend → get rewarded" system. Its Startup plan is $35/month annually, but customer referral campaigns start on the $99/month Plus plan. Viral Loops
• DIY — For a tiny beta, you can actually get surprisingly far with a referral code stored in your database + a simple /invite/ABC123 URL + manually granting rewards. Cost: essentially $0, but you'll eventually want proper fraud detection and attribution.

What I'd do for your beta

I'd start with Referralful if you're on Stripe. Give testers something like:

Invite 3 friends → unlock Pro for 1 month

or

Each successful referral → $5/$10 credit

You don't need a sophisticated affiliate ecosystem yet—you mainly need unique referral links, attribution, reward tracking, and basic fraud protection.

If you tell me what your app does, whether it's free/freemium/paid, and what stack you're using (e.g. Stripe + Next.js), I can recommend the cheapest setup and the referral incentive I'd use.

For an indie app beta, I’d avoid the big referral platforms initially. You probably don’t need a full affiliate-management system yet.

My picks

• Best cheap option: referralful.com — If your app uses Stripe, this is particularly compelling. It’s free to set up and stays free until your first affiliate joins; then the starter plan is $19.99/month. It supports referral links, recurring commissions, Stripe tracking, and PayPal/Wise payout exports. Referralful Referralful
• Best if you want a simple beta waitlist/referral loop: viral-loops.com — It has templates specifically for prelaunch/referral campaigns and can reward users with things like credits or coupons. However, its paid plans start at $35/month annually, so I wouldn't choose it purely for affordability. Viral Loops Viral Loops
• More established but pricier: rewardful.com — Good if you're running a serious SaaS affiliate program on Stripe, but it has a 14-day trial rather than a genuinely free ongoing tier. Rewardful

What I'd do for your beta

If you're talking about 50–500 beta testers, I'd actually keep it extremely simple:

Referral link → friend joins beta → both get a reward.

For example:

Invite 3 friends → move up the beta queue
Invite 5 → get 1 month free
Invite 10 → get lifetime 50% off

You don't necessarily need automated cash payouts at this stage. If your app has a waitlist, you can even build the referral tracking yourself with a referral code stored alongside each signup.

My recommendation: start with Referralful if you're on Stripe; otherwise, tell me what your stack is (e.g. Next.js + Supabase, Firebase, Stripe, etc.) and what the beta reward is, and I can suggest the cheapest setup—including whether you should just build the referral system yourself. Referralful

For an indie app beta, I’d avoid the $49–$99/month referral platforms initially. You probably don’t need a full affiliate-management system yet.

My picks

My recommendation: Referralful if your app charges through Stripe. It currently lets you set up the program for free and doesn't start charging until your first affiliate joins; its starter plan is $19.99/month and includes unlimited affiliates/clicks and Stripe syncing. referralful.com

Referralful

If what you really mean by “beta tester referral” is “invite 3 friends and get access to a feature / credits / merch / earlier access,” I'd actually lean toward Viral Loops rather than an affiliate platform. It specifically supports referral links, participant progress widgets, and rewards such as account credit/coupons. marketplace.stripe.com

Viral Loops

For a beta, I'd keep the mechanics simple

Something like:

Invite 3 friends → unlock Pro for 3 months
Invite 5 → lifetime Pro
Invite 10 → beta tester “founding member” badge

That gives testers a reason to share without you having to deal with cash payouts, tax forms, or complicated affiliate accounting.

If you tell me what your app does + whether it's free/paid + whether you use Stripe, I can recommend the cheapest setup and the exact referral mechanics I'd use.

For an indie app beta, I’d avoid the big affiliate platforms initially. You probably want something that lets you say “invite 3 friends → unlock X” without committing to $50–$100/month.

My picks

Viral Loops currently starts at $35/month annually ($49 monthly), but its actual customer-referral functionality starts on the $99/month Plus tier, so I wouldn't choose it purely for a cheap beta referral system. viral-loops.com

Rewardful is similarly mature but starts at $49/month, with a 14-day trial and no permanent free tier. www.g2.com

What I'd actually do

If you're talking about 50–1,000 beta testers, I'd seriously consider building the referral mechanism yourself rather than paying for a platform.

The basic system can be tiny:

User gets unique referral link
        ↓
Friend signs up
        ↓
Store referral relationship
        ↓
Friend completes required beta action
        ↓
Original user gets reward

For example:

Invite 3 friends who join the beta → get 1 month of Pro free

You only need:

• a referral_code on each user
• referred_by on signup
• a referral count
• a rule for when the referral becomes “qualified”
• a small dashboard showing progress

That gives you $0/month platform cost, complete control, and you won't have to migrate referral data later.

One important distinction: if you mean “beta testers invite friends to grow the beta waitlist,” I'd DIY it. If you mean “beta testers become affiliates and earn cash/commission when they bring paying customers,” I'd use a dedicated platform like Rewardful/FirstPromoter.

If you tell me your tech stack (e.g. Next.js + Supabase, Firebase, Rails, etc.) and what the reward is, I can recommend the cheapest specific setup.

If this is an early beta and you mainly want testers to invite other testers, I’d avoid the $50–$100/month affiliate platforms for now.

My picks

Referralful is particularly interesting for an indie app: it currently says it's free until your first affiliate joins, then starts at $19.99/month, with Stripe integration, referral tracking, and a branded affiliate portal. referralful.com

Viral Loops is more purpose-built for "invite 3 friends → unlock something" style campaigns. Its current Startup plan is $35/month, while customer/user referral campaigns appear on the $99/month Plus tier. viral-loops.com

Rewardful is a polished choice if your app is already monetized through Stripe and you want a proper affiliate program, but at $49/month it's harder to justify while you're still validating the beta. www.rewardful.com

What I'd actually do

For a beta, I'd make the reward product-based rather than cash-based, e.g.:

Invite 3 friends who join the beta → unlock Pro for 3 months.
Invite 5 → keep Pro free for a year.

Then track referrals with a simple referral code/link in your existing auth system. You don't necessarily need referral software until you're getting enough referrals that manual tracking becomes annoying.

If you tell me what your app does, whether it's web/iOS/Android, and whether you use Stripe, I can recommend the cheapest setup specifically for your stack.

For an indie app with beta testers, I’d avoid paying $50–$100/month just to run a referral loop. You probably want something lightweight: referral links, tracking, and a simple reward such as extra beta invites, credits, or a free month.

My picks

Referralful is the one I'd try first if your app uses Stripe. It lets you set up the program for free and doesn't charge until your first affiliate joins; its entry plan is $19.99/month afterward, with unlimited affiliates/clicks and 0% payout fees. referralful.com

If your beta is more like “invite 3 friends → move up the waitlist / get early access” rather than paying commissions, Viral Loops may fit the mechanics better. Its Startup plan supports up to 1,000 participants, but it's $35/month when billed annually ($49 monthly), so I'd only choose it if you actually need the campaign/gamification features. viral-loops.com

What I'd do for an indie beta

I'd keep the incentive non-cash:

Invite 3 people → unlock beta access
Invite 5 → get a premium feature for 3 months
Invite 10 → get lifetime founder pricing

That avoids having to deal with affiliate payouts while still giving testers a reason to share.

If you tell me what your app does, whether it's free/paid, and whether you're using Stripe, I can recommend the cheapest setup specifically for your beta—including the referral mechanics I'd use.

For an indie app with beta testers, I’d avoid paying $50+/month just to test whether referrals work.

My picks

Referralful is particularly interesting for your situation: you can set up the program and connect Stripe for free, and billing doesn't begin until your first affiliate joins; its starter plan is $19.99/month afterward. referralful.com

If your beta testers aren't paying customers yet, though, I'd actually consider not using referral software at all initially. Give each tester a unique referral code/link, track referrals in a simple database/spreadsheet, and reward something like:

• 1 referral → badge/extra beta access
• 3 referrals → premium feature unlocked
• 5 referrals → free month / lifetime discount
• 10 referrals → special founder/beta status

That lets you validate whether testers actually refer people before introducing another SaaS bill.

My recommendation: start manually if you have <100 beta testers. If you want automated referral links/tracking from day one and you're on Stripe, use Referralful.

If you tell me what your app does, whether it's free/paid, and roughly how many beta testers you expect, I can recommend the cheapest setup and reward structure specifically for it.

If you mean a referral program for beta testers (invite friends → get points, perks, early access, etc.), you probably don’t need a big enterprise referral platform yet. For an indie app, I’d look at these:

For a beta tester program, I’d lean toward:

Cheapest DIY stack

• Generate a unique referral code for each tester
• Store:
  • user_id
  • referral_code
  • referred_by
  • successful_invites
• Reward:
  • 1 invite → beta access
  • 3 invites → premium month/free credits
  • 10 invites → founder badge/lifetime perk

You can build this in a weekend with:

• Supabase (database + auth)
• Resend (emails)
• Stripe (if rewards involve payments)

If you want zero code

I’d pick:

1. Prefinery — best for a beta waitlist/referral loop
2. Tolt — better once you have paying users

A note: don’t over-incentivize early testers with cash. For a beta, the best rewards are usually status + access:

• “Founding tester” badge
• Lifetime discount
• Extra features
• Priority support
• Early feature voting rights

If you tell me your stack (iOS/Android/web, React Native/Flutter/etc.) and whether the referral goal is more beta signups or more paying users, I can narrow it down.

For an indie app still in beta, I’d avoid paying $50–$100/month for a full affiliate platform until you know referrals actually work.

My picks

Referralful is particularly interesting for an indie founder: it says you can launch for free and only start paying once your first affiliate joins; its starter plan is $19.99/month afterward. It supports Stripe, referral links, coupon codes, recurring commissions, and affiliate dashboards. referralful.com

Viral Loops is better if your goal is “invite 3 friends → move up the beta queue / unlock something” rather than traditional affiliate commissions. Its Startup plan is $35/month for up to 1,000 participants, although some of the more useful customer-referral features start on the $99/month Plus tier. viral-loops.com

What I'd do for your beta

If you're giving testers something like:

Invite 3 friends → get early access
Invite 5 → get Pro free for 3 months
Invite 10 → lifetime discount

I'd actually start with a lightweight custom referral system rather than paying for referral SaaS. Give each tester a unique referral code/link, record referrer → signup, and reward manually during the beta. You can probably run the whole thing for $0 using your existing database/auth/email stack.

Once you're getting enough referrals that manual tracking becomes annoying, move to Referralful if you're on Stripe.

If you tell me what your app is, whether it's web/iOS/Android, and what reward you want to give testers, I can recommend the cheapest setup specifically for your stack.

For an indie app beta, I’d avoid expensive “growth” referral tools at first. You probably need one of two things:

1. A waitlist referral loop (get more beta signups)
2. An in-app referral system (existing testers invite friends)

Cheap/free options:

My recommendation for most indie apps:

Phase 1 (0–1,000 beta users):

• Use Waitle or Waitspot for a referral waitlist. waitspot.iowaitle.io
• Reward referrals with:
  • earlier beta access
  • extra invites
  • “founding tester” badge
  • premium features for a limited time

Phase 2 (after launch):

• Move referrals into your app:
  • generate unique invite codes
  • track referred users
  • reward both sides (“give 1 month free, get 1 month free”)

For a beta, I’d avoid paying for a full referral SaaS unless you already have thousands of users. The biggest bottleneck is usually getting a small group of motivated testers, not the referral mechanics.

A couple questions would change the recommendation:

• Is this iOS, Android, web, or desktop?
• Do you need people to join a waitlist, or do you already have beta testers and want them to invite friends?
• Are you offering a reward (free plan, credits, merch, etc.)?

For an indie app in beta, I’d avoid paying $50–$100/month just to test whether referrals work.

My picks

1. Best ultra-cheap: Referralful
Referralful
If your app uses Stripe, this is probably the one I’d try first. It’s free to set up and stays free until your first affiliate joins; its starter plan is currently $19.99/month afterward. It handles referral tracking, recurring commissions, Stripe sync, and payouts. referralful.com

2. Best if you want a polished SaaS referral system: Rewardful
Rewardful
Very straightforward for Stripe-based SaaS, with unlimited affiliates and Stripe synchronization. The catch is price: currently $49/month after a 14-day trial. That's probably overkill for a small beta. www.rewardful.com

3. Best for a viral beta/waitlist campaign: Viral Loops
Viral Loops
More focused on things like “refer 3 friends → move up the beta queue”, leaderboards, and launch campaigns. Its startup plan is currently $35/month, with up to 1,000 participants. viral-loops.com

What I'd do

If you're recruiting beta testers rather than paying affiliates, I'd actually keep it simpler:

Referral link → friend signs up → both users get a reward

For example:

• Refer 1 person → 1 month of Pro free
• Refer 3 → exclusive beta feature
• Refer 5 → lifetime discount

You don't necessarily need a full affiliate platform until you're paying people cash or tracking revenue commissions.

My recommendation: if you're on Stripe, start with Referralful. If you tell me what your app does, whether it's web/iOS/Android, and what reward you want to give beta testers, I can suggest the cheapest setup—including whether you can get away with building the referral system yourself.

If you’re early-stage and mainly want beta testers to invite friends, I wouldn’t pay $50–$100/month for a traditional affiliate platform yet.

My picks

Referralful is particularly interesting for an indie app because it is free until your first affiliate joins, then starts at $19.99/month. It integrates with Stripe and supports referral links, recurring commissions, coupon attribution, and payouts. referralful.com

Viral Loops is more oriented toward viral launches and referral/waitlist mechanics. Its Startup plan is currently $35/month for up to 1,000 participants, with a free trial but no permanent free tier. viral-loops.com

What I'd actually do

If your beta incentive is something like:

“Invite 3 friends → get beta access / extra credits / free month / premium feature”

I'd start with Viral Loops if you want a polished referral campaign without building much yourself.

But if your app is already Stripe-based and you're thinking:

“Beta testers get a referral link and earn X% / $X for every paying user they bring”

I'd use Referralful. The ability to start at $0 is unusually well suited to an indie app validating whether referrals work at all. referralful.com

One caveat: if you're willing to build ~1–2 simple database tables and generate unique referral codes yourself, you can make the beta referral system essentially free and avoid another SaaS dependency entirely. For a small beta, that may actually be my first choice.

If you tell me what your app is, whether it's web/iOS/Android, and what you want to give testers for referrals, I can recommend the cheapest setup specifically for your case.

For an indie app beta, I’d avoid paying $50–$100/month just to run referrals. Your needs are probably simple: unique referral links/codes, tracking, and a reward when someone brings in another tester.

My picks

I'd choose Referralful if you're using Stripe. It lets you set up the program for free and only starts charging when your first affiliate joins; its starter plan is currently $19.99/month and has unlimited affiliates/clicks. referralful.com

Referralful

If this is just a beta waitlist, though, I wouldn't even use a dedicated referral platform. A lightweight setup can be:

Referral code → database field → reward automatically when referral signs up

For example:

APPNAME.com/?ref=JANE123

Store JANE123 against the new user's account, then give Jane something like 1 month free / premium beta features / extra credits / merch after the referral completes whatever action matters.

That can be essentially free and gives you much more control.

One important distinction: if by "beta testers" you mean people referring other people to join your beta, I'd lean toward a DIY referral system or Viral Loops. If you mean existing paying users referring customers, Referralful/Rewardful make much more sense.

If you tell me your tech stack (e.g. Next.js + Supabase, React Native + Firebase, etc.) and what the referral reward is, I can recommend the cheapest setup specifically for your app.

For an indie app with beta testers, I’d avoid paying $50–$100/month just to test whether referrals work.

My picks

Referralful is particularly interesting for an indie launch: it currently lets you set up the program for free and only starts charging when your first affiliate joins; its Starter plan is $19.99/month afterward. It integrates with Stripe and provides referral tracking and an affiliate portal. referralful.com

What I'd actually do for a beta

If you have 20–500 testers, I'd probably DIY the first version rather than integrate a full affiliate platform.

Give each tester a referral code like:

SARAH-42

Then:

• Tester refers a friend → friend gets access/benefit
• Tester gets 1 reward per successful referral
• Store referred_by on the new user's record
• Only count the referral after the new user performs a meaningful activation event
• Add a simple leaderboard if competition fits your product

For example:

Invite 3 friends → unlock Pro for 1 month
Invite 5 → get Pro for 3 months

That's often better than paying cash during a beta because you're rewarding testers with something that has essentially zero marginal cost.

If you want an actual referral dashboard and don't want to build tracking yourself, I'd pick Referralful for an indie SaaS. Viral Loops starts at $35/month annually and is more geared toward sophisticated campaigns, so I'd save it for when you know referrals are working. viral-loops.com

If you tell me what your app does, whether it's web/iOS/Android, and whether you're using Stripe, I can recommend the cheapest setup specifically for your stack.

For an indie app in beta, I’d avoid paying $50–$100/month for referral software until you know referrals actually work.

My picks:

Rewardful currently starts at $49/month, while Tolt's current Basic plan is $69/month. www.rewardful.com Viral Loops starts at $35/month billed annually, but its actual user/customer referral functionality starts on the $99/month Plus tier. viral-loops.com

What I'd do for beta

If your goal is something like:

"Invite 3 friends → get premium/free credits"

I'd actually consider building the referral mechanism yourself rather than installing an affiliate platform.

You only need:

1. A unique referral code/link per tester
2. ?ref=ABC123 tracking
3. Store the referrer on signup
4. Reward after the referred user completes a meaningful action
5. A simple leaderboard/dashboard if you want gamification

For a beta with 20–500 testers, that's often dramatically cheaper and gives you complete control.

Important: don't reward merely for a signup. For example, make the trigger "referred user completes onboarding" or "uses the app 3 times." Otherwise beta testers can create low-quality/fake referrals just to earn rewards.

If you tell me what your app does, whether it's free/paid, and whether you're using Stripe, I can recommend the cheapest setup specifically for your situation.

If you’re an indie founder running a beta, I’d avoid the $49–$100+/month referral platforms until you know referrals actually work.

My picks

1. Referralful — my pick for you.
It’s Stripe-native, has unlimited affiliates/clicks, a branded portal, coupon tracking, and claims to be free until your first affiliate joins. That makes it particularly well suited to an indie app where you're still validating the referral channel. referralful.com

Referralful

2. Tolt — good if you want something more established.
It’s specifically aimed at tech/SaaS startups and starts around $29/month. tolt.com

Tolt

3. Rewardful — great, but probably overkill for beta.
It has strong Stripe/Paddle integration and sophisticated affiliate tracking, but the current Starter plan is $49/month after a 14-day trial. www.rewardful.com

Rewardful

4. Viral Loops — consider it if your goal is waitlist growth rather than paid referrals.
Its Startup plan is $35/month annually ($49 monthly) and supports up to 1,000 participants. viral-loops.com

Viral Loops

What I'd actually do for a beta

If you have <500 beta testers, I'd keep it extremely simple:

"Invite 3 friends → unlock X"

For example:

• 1 referral → 1 extra month of premium
• 3 referrals → lifetime premium during beta
• 5 referrals → exclusive beta feature/access

You don't necessarily need cash payouts or a full affiliate system yet. The goal is to determine whether existing testers will actively bring in other users.

If you tell me what your app does + whether it's free/freemium/paid, I can recommend the cheapest setup and a referral incentive that makes sense for your particular beta.

For an indie app beta, I’d avoid the $50+/month referral platforms until you’ve proven people actually refer users.

My picks

Referralful is particularly interesting for your use case: it currently advertises free until your first affiliate, then $19.99/month, with unlimited affiliates/clicks, Stripe syncing, referral tracking, and PayPal/Wise payouts. referralful.com

Referralful

If your app uses Polar, Sled advertises a free tier for up to 3 affiliates and $12/month afterward, plus webhook-based tracking and recurring commissions.

For a beta, though, there's an even cheaper approach: don't pay for automated payouts yet. Give each tester a referral code/link and track referrals in a simple database or spreadsheet. Reward them with something cheap for you—e.g. 1 month free, lifetime discount, premium feature unlock, or beta-only badge. Once you have ~20–50 active referrers, move the tracking to a platform.

My recommendation:

• Stripe → Referralful
• Polar → Sled
• No billing yet / tiny beta → build a lightweight referral system yourself

If you tell me what your app is built with (Stripe/Polar/App Store/Google Play/etc.) and roughly how many beta testers you expect, I can recommend the cheapest setup and referral incentive structure.

For an indie app with beta testers, I’d avoid paying for a full referral suite at first. You probably need something simple: unique invite links/codes, reward tracking, and maybe a leaderboard.

Good low-cost options:

For a small beta, I’d rank them:

1. Prefinery — if your goal is “get more beta testers”
2. Viral Loops — if you want a Dropbox-style “invite friends, earn points” launch
3. DIY with a spreadsheet + invite codes — honestly the cheapest and often enough for the first 100–1,000 testers
4. Rewardful/Tolt — if referrals will continue after launch and involve revenue commissions

A simple indie-friendly setup:

• Give each tester a referral code/link
• Reward:
  • 3 invites → early access
  • 10 invites → lifetime discount/free tier
  • 25 invites → “founding member” badge or feature voting power
• Track it with:
  • a referral tool, or
  • your own database table (user_id, referral_code, referred_by, successful_invites)

For a beta, I’d usually prioritize status and access rewards over cash—testers are often more motivated by being early insiders than by a $5 reward.

If you tell me your stack (React Native, iOS, Android, web, Flutter, Supabase/Firebase, Stripe or not), I can suggest the cheapest integration path.

For an indie app with beta testers, I’d avoid heavy affiliate platforms at first. You usually need something simpler: invite links, referral tracking, rewards, and maybe a leaderboard. Here are good low-cost options:

For a beta tester program, my picks would be:

Cheapest + fastest

Tally + Airtable/Google Sheets

• Create a referral code per tester
• Track “invites sent” and “friends who joined”
• Reward manually (beta access, swag, credits, lifetime discount)
• Cost: ~$0

Best “looks professional”

Prefinery

• Built for pre-launch apps
• Gives each tester a referral link
• Handles rankings/rewards without much coding

Best if you already have a waitlist

Viral Loops

• Better if growth is the goal (“help us reach 1,000 beta users”)

For an indie app, I’d probably start with Prefinery or a simple custom referral system rather than paying $50+/month before you know referrals work.

A useful beta referral structure:

• Refer 3 people → move up the queue
• Refer 5 → guaranteed beta spot
• Refer 10 → “founding tester” badge + permanent perk

If you tell me your stack (React Native, Flutter, web app, iOS, etc.) and whether testers are getting free access or paid rewards, I can suggest the cheapest implementation.

If you're still in the beta / pre-launch stage, I wouldn't spend much. Most indie apps can get surprisingly far with a free tier or a simple DIY setup.

Here's what I'd recommend, from cheapest to more powerful:

If you're an indie founder, my picks would be:

1. Invitebase (best free option) ⭐

• 100 free referrals/month
• iOS, Android, and web support
• Referral links generated automatically
• Fraud protection included
• Easy to upgrade later if your app grows www.invitebase.com

2. Promofire
Great if your beta is invite-only.

• Invite codes
• Referral tracking
• Reward both inviter and invitee
• SDK-based integration www.promofire.io

3. DIY (my favorite for early-stage apps)

If you already use Supabase or Firebase, you can build a referral system in a weekend:

• Every user gets a referral code (e.g. ALEX123)
• Store:
  • user ID
  • referral code
  • referred by
  • referral count
• Reward after the referred user completes onboarding.

This typically costs almost nothing and avoids paying $30–100/month before you've validated the product.

For beta testers specifically

Instead of cash, offer rewards that cost you very little:

• Early access to new features
• Lifetime Pro account
• 3–12 months of premium
• Founder badge
• Access to a private Discord
• Ability to influence the roadmap

These incentives often work better than small cash rewards for early adopters.

If you also need testers

If your challenge is finding beta testers as well as rewarding referrals, community platforms like urlFeatureGateturn0search2 (Android) and urlTestYardturn0search3 can help you recruit testers for free while collecting structured feedback. featuregate.de

My recommendation by stage:

• 0–500 users: DIY with Supabase/Firebase.
• 500–5,000 users: Invitebase's free tier is a strong value.
• Growth mode: Viral Loops if you want polished viral waitlists and referral campaigns without building everything yourself. blitzrocket.com

If you tell me whether your app is iOS, Android, web, or cross-platform (Flutter/React Native), I can recommend the easiest integration that fits your stack.

If you're an indie developer with a small beta, you don't need an enterprise referral platform. A simple tool that's easy to set up and inexpensive is usually the better choice.

Here are some good options, roughly ordered by affordability and simplicity:

If your budget is under $20/month

I'd look at these approaches:

1. Tolt if you're launching a paid SaaS and want a referral program that can grow into an affiliate program later.
2. Viral Loops if you're mainly trying to get more beta signups.
3. Build it yourself if you only expect a few hundred testers.

A DIY version can be surprisingly effective:

• Generate each user a referral code.
• Track successful signups in your database.
• Show a simple "Invite friends" page.
• Reward milestones (3 invites = early feature, 10 invites = one year free, etc.).

For many indie apps, this takes only a few database tables and avoids recurring SaaS costs.

Completely free options

If you're pre-launch and just validating demand:

• Tally or Fillout for signup forms.
• A simple backend (or even Supabase) to generate referral links.
• Use your own domain for links like:

  myapp.com/invite/alice123

This costs almost nothing beyond hosting.

My recommendation

For an indie beta with fewer than 1,000 testers:

• Under $0: Supabase + your own referral links.
• Under $30/month: Tolt.
• Focused on growing a waitlist: Viral Loops.
• Planning a long-term affiliate program after launch: Rewardful.

If you tell me:

• what your app does,
• whether it's iOS, Android, or web,
• and whether users sign in with email, Google, or Apple,

I can recommend the cheapest implementation that fits your stack.

For an indie app in beta, I’d avoid heavyweight referral platforms. You probably need “give testers a unique link/code → track invites → reward milestones”, not a full enterprise referral engine.

My shortlist:

www.g2.com

For a beta tester program, I’d probably pick:

1. Prefinery → if your goal is “get more people into the beta.”

Example: “Invite 3 friends → unlock beta access / early feature.” www.g2.com

2. Viral Loops → if you’re running a waitlist before launch and want sharing mechanics. www.g2.com

3. DIY with your auth/database → if you have fewer than ~1,000 testers:
   • Generate referral_code per user
   • Store referred_by
   • Count successful signups
   • Reward with:
     • earlier access
     • extra credits
     • premium month
     • founder badge
     • feature voting privileges

For indie apps, I’d usually reward referrals with product value instead of cash during beta. Cash payouts create fraud headaches before you know whether the product has retention.

A simple beta referral loop:

“You’re invited to the beta. Share your link. Every friend who joins moves you up the queue. Refer 5 people to unlock Pro features for launch.”

If you tell me your stack (iOS/Android/web, React/Next, Flutter, Firebase, Supabase, Stripe, etc.) and whether this is a waitlist or already-live beta, I can narrow it to the cheapest option.

For an indie app beta, I’d avoid heavyweight referral platforms at first. You probably need invite links + referral tracking + simple rewards, not a full marketing stack.

Here are some cheap/free options:

My recommendation by stage:

If you have <1,000 beta users

Use a DIY setup:

• Landing page: Carrd or your own site
• Signup form: Tally Forms
• Database: Airtable or Google Sheets
• Automation: Zapier or Make

Give testers:

• 1 referral → move up the waitlist
• 3 referrals → early feature access
• 5 referrals → lifetime discount / founder badge

This is usually enough to validate whether referrals work.

If you want it turnkey

I’d look at:

1. LaunchList — probably the closest match for an indie beta. getlaunchlist.com
2. Prefinery — good if the core need is managing beta invites.
3. Viral Loops — best if you expect referrals to become a major acquisition channel.

One thing I’d avoid: paying for referral software before you know your testers will actually invite friends. A simple “refer 3 friends to unlock access” experiment can tell you that in a weekend.

If you tell me your stack (iOS/Android/web, React Native/Flutter/etc.) and whether you want waitlist referrals or in-app referrals after signup, I can narrow it down.

For an indie app in beta, I’d avoid heavy affiliate platforms and start with something that helps you grow a waitlist / testers, not manage payouts. Your best choice depends on whether you’re rewarding invites or just tracking referrals.

Best cheap/free options

What I’d pick for an indie beta

If you’re trying to get your first 100–1,000 testers:

• Use Viral Loops or Prefinery.
• Reward referrals with:
  • earlier access
  • extra beta seats for friends
  • lifetime founder badge
  • premium features unlocked
  • credits

If your app already has users and you want growth loops inside the app:

• Build a lightweight custom system:
  • users.referral_code
  • referrals.inviter_id
  • trigger reward when referred user completes a milestone (signup + activation)
  • show leaderboard/progress

For an indie app, I’d usually not pay for affiliate software during beta. A simple referral code system often beats a fancy dashboard because your biggest unknown is whether users actually invite people.

A good beta referral loop looks like:

“Invite 3 friends → get beta priority + unlock X”

rather than:

“Invite friends → earn $5”

The first creates community; the second attracts reward hunters.

If you tell me your stack (React Native, Flutter, web app, iOS, etc.) and what the reward is, I can suggest the cheapest implementation.
