RevenueCat specializes in in-app purchases and subscriptions for mobile apps, unifying Apple App Store and Google Play billing behind one API.
RevenueCat only makes sense if you're shipping a mobile app — it doesn't replace Stripe or Paddle for a web SaaS. It sits on top of Apple App Store and Google Play billing so you don't have to write platform-specific subscription code twice.
