Subscription validation,
finally done right.
One API for Apple App Store, Google Play, and Stripe subscriptions. Receipt verification, entitlement state, webhooks, and admin controls — all in a single dashboard your team actually wants to use.
No credit card required · Set up in under 10 minutes
Everything you need
The subscription backend your team doesn't have to build.
Stop wiring Apple notifications, Google developer events, and Stripe webhooks into one more half-working state machine. We already built it, tested it in production, and shipped it as a single API.
Verified receipts
Apple App Store Server, Google Play Developer API, and Stripe signatures — all verified server-side before anything touches your data.
Fast reads everywhere
Global edge caching with intelligent invalidation. Sub-100ms entitlement checks whether your user is in Tokyo, Berlin, or Toronto.
Proper state machine
Trial, active, grace, cancelled, refunded, expired — transitions handled per provider semantics. No more out-of-order renewal bugs.
Multi-tenant ready
Run one instance for all your apps. Each tenant has isolated data, credentials, and analytics. Perfect for app studios and agencies.
Developer-first SDK
Drop-in JavaScript and TypeScript SDK for browsers, React Native, and server runtimes. Typed entitlement reads, automatic retries, built-in caching.
Admin grants and campaigns
Gift premium to a single user or run bulk campaigns. Full audit trail, reason codes, and optional recipient emails — no Slack pings to engineering.
How it works
From receipt to entitlement in three steps.
01
Register your app
Create a tenant in the dashboard. Upload your Apple, Google, and Stripe credentials. They're encrypted at rest and never shown back.
02
Point your webhooks
Paste three URLs into Apple App Store Connect, Google Cloud Console, and the Stripe dashboard. We handle the rest.
03
Call the SDK
Import the SDK in your app, ask isActive(userId, 'pro'), and get an answer in milliseconds. Done.
