How I built an embeddable affiliate program for SaaS (no dashboards, 0% fees, no earning limits)

Affiliate programs are a great growth engine — but most SaaS tools make it harder than it should be.

I wanted a way to give my users referral tools inside my product. Not a separate platform. Not more tabs.

So I built Refgrow — a fully embeddable affiliate engine designed for SaaS.

Problems I had with existing tools:

• Redirecting users to external dashboards
• Commission fees on affiliate payouts
• Earning caps (e.g. Rewardful limits you to $7.5k/month on the base plan)

What I built instead:

• Fully embedded affiliate UI
• 0% payout fees
• Works with Stripe, Paddle, and LemonSqueezy
• Unlimited revenue from affiliates, even on the cheapest plan
• REST API, mass payouts, white label options available

Tech stack:

• Vanilla JS snippet
• Hosted tracking logic + analytics
• Customizable UI, designed to be styled to match your brand

TL;DR:

Launch an affiliate program inside your SaaS in 5 minutes. No commissions. No caps.

Curious to hear: how are you handling referrals in your own product?
