GrowthRail is a developer-first referral platform to launch and manage native referral programs. Integrates via drop-in SDKs & referral APIs for SaaS, web, and mobile apps.

We've been building mobile and web apps for years, and every time we wanted to add referrals, we hit the same wall. The existing tools were expensive, had no useful free tier, and took more effort to integrate than they should have. Yet referrals are a great way to grow your app organically, and a great indicator of customer loyalty. So we built GrowthRail. GrowthRail is referral and attribution infrastructure for mobile and web apps. Here's what you get at launch: • Native SDKs for Swift and Kotlin, plus JavaScript, React, React Native, and Expo • Drop-in referral UI for share links and promo codes • Integrations with Clerk, Stripe, RevenueCat, Lemon Squeezy, PayPal, and more • Attribution across web, iOS, and Android It's free to get started. For launch week, our Early Adopter plan gives you 4× the free tier's usage, free forever once claimed. When we introduce paid plans for higher usage, your Early Adopter benefits will be continued. growthrail.dev I'm curious: what's stopped you from adding referrals to your app? Is it pricing, integration effort, or getting attribution right? Happy to answer any questions and would love to hear your feedback.

Great launch. Quick question, are you planning on adding more auth provider integrations?

@mahendrabishnoi2 Thanks for the feedback, Mahendra.
Yes, we're planning to add more providers like Firebase, Supabase and Auth0 in the very near future.

@mahendrabishnoi2 @zyur_io Would love to see better auth as well!

@mahendrabishnoi2 @ithihas_madala Better Auth is part of the roadmap as well.
