How it works
A referral program inside your app, in 5 minutes.
Third-party portals get forgotten. A tab inside your product gets seen every day by the people most likely to recommend you: your paying customers.
- 01
Connect Stripe
Paste a restricted key. We register the webhook and read your brand from your site.
- 02
Paste one snippet
A script tag and <reftab-tab>. Or hand the ready-made prompt to Claude Code or Cursor.
- 03
Customers share, rewards apply
When a friend pays, both get rewarded in your own Stripe after the hold period.
<!-- 1. on every page -->
<script src="https://reftab.app/reftab.js" data-key="rt_pub_live_…" defer></script>
<!-- 2. wherever the tab lives -->
<reftab-tab token="{signedUserToken}"></reftab-tab>
Rewards
You pick the reward. Your Stripe applies it.
In-product rewards avoid tax forms entirely. Make it double-sided so the friend gets something too: it's what makes people actually share.

Calculator
What could a referral program bring you?
Move the sliders. The math is simple and the assumptions are on screen.
Assumes each customer who shares brings 0.5 paying friends on average, and a “give a month, get a month” program. In-app tabs are seen far more often than external portals, so 10% is a sensible starting point.

The tools that embed are expensive. The cheap ones are portals.
Nobody else offers a free, embedded tab where you choose between cash and in-product rewards.

Questions
Is it really free?+
Yes. Unlimited referrals, unlimited referred revenue, every in-product reward type, the embedded tab and the dashboard are free forever. Pro sells polish: no branding, cash commissions, multiple programs and the API.
Do you ever touch my money?+
Never. In-product rewards are applied in your own Stripe account as credits, coupons or plan changes. Cash commissions are paid from your own PayPal or Wise using a payout file we generate.
How long does setup take?+
About five minutes: connect Stripe with a restricted key, paste one script tag and drop the <reftab-tab> element into your settings page. There's a copy-paste prompt for Claude Code and Cursor too.
What stops people from referring themselves?+
Self-referrals with the same email, Stripe customer or card are blocked automatically. Bursts of signups from one referrer are flagged for review, and every reward waits out a hold period (30 days by default) so refunds cancel it.
Can I try it without touching billing?+
Yes. Test mode runs the whole loop with a built-in simulator, or against your Stripe test data. Switch to live when you're happy.
Does it work with AI agents?+
Everything the dashboard does is available through our MCP server. Ask Claude to “set up a give-a-month program and add the tab to my settings page”.
