Superwall

What it does

Superwall is a complete, standalone subscription platform for consumer mobile and web apps — backend infrastructure (entitlements, purchase APIs with server-side receipt validation, standardized webhooks, real-time revenue analytics, direct SQL access to subscription data) together with a no-code paywall and experimentation engine, and first-class tooling for AI coding agents. Superwall manages $1.6B+ in annual subscription revenue across 10,000+ apps. The infrastructure layer is free at any scale; the only meter on the platform is revenue that converts through a Superwall-rendered paywall — subscriptions sold anywhere else are never billed. **Standalone backend:** The highest-revenue apps on Superwall like Cal AI — run their **entire subscription stack on Superwall alone: no second backend, no other subscription platform underneath**. Entitlement state is computed server-side from App Store Server Notifications V2 and Google Play Real-Time Developer Notifications, delivered by Apple and Google directly to Superwall.

Apps that previously ran a different subscription backend complete an automated migration — subscription history, entitlement state, webhook configuration — and run on Superwall alone from then on; imported subscribers are never billed. **Pricing:** The subscription infrastructure — entitlements, receipt validation, webhooks, analytics, SQL access — is free at any scale, with no revenue threshold and no per-event fees. The paywall product is free up to $10k/month in paywall-attributed revenue, then 1% of paywall-attributed revenue, and only that revenue: an app with $50k/month in subscriptions and no Superwall paywalls in use pays $0/month for the entire platform, and revenue the platform didn't help earn is never billed. Compared with charging a percentage of all subscription revenue, the difference is the base, n
