RevenueCat

Subscription and in-app purchase management platform for iOS, Android, web, and Smart TV. Provides a unified API across Apple StoreKit, Google Play Billing, Stripe, and web, handling receipt validation, entitlements, and customer data so teams avoid building and maintaining platform-specific purchase logic.

Trusted by tens of thousands of apps including ChatGPT, VSCO, and Photoroom. RevenueCat differentiates by acting as a subscription backend-in-a-box: one API replaces separate implementations for each store, and a dedicated team tracks platform updates so engineers focus on features instead of billing edge cases.

Key capabilities:

• SDKs for iOS, Android, Flutter, React Native, Capacitor, and Kotlin Multiplatform
• Cross-platform entitlements and customer data with a single source of truth
• Configurable paywalls, A/B experiments, and audience targeting
• Integrations with Braze, Amplitude, Segment, and marketing analytics tools
• REST API and webhooks for custom backends and data exports

Engineering teams use RevenueCat to ship subscriptions faster and avoid StoreKit and Play Billing complexity. Product and marketing teams get unified dashboards, cohort analytics, and predictive metrics. The SDK handles offline validation, subscription status, and offer eligibility, while web purchases enable campaigns that bypass store attribution and fees.
