RevenueCat is a powerful, reliable, and free to use in-app purchase server. Our open-source framework provides a backend and a wrapper around Apple's StoreKit and Google Play Billing to make implementing in-app purchases and subscriptions easy.

Whether you are building a new app or already have millions of customers, you can use RevenueCat to:

• Fetch products, make purchases, and check subscription status with our native SDKs.
• Host and configure products remotely from our dashboard.
• Analyze the most important metrics for your app business in one place.
• See customer transaction histories, chart lifetime value, and grant promotional subscriptions.
• Get notified of real-time events through webhooks.
• Send enriched purchase events to analytics and attribution tools with our easy integrations.

Here are a few ways to get started:

• Adding subscriptions to a new app? Jump right in with our Quickstart Guide.
• Already have an app with subscribers or purchases? The Migration Guide is useful if you're moving an existing app's IAP infrastructure to RevenueCat.

Not a developer?

Although implementing RevenueCat requires you to be (or hire) a developer, our dashboards and integrations are designed to be used by marketers, analysts, and customer success teams of forward-thinking app businesses. Talk to your engineering team about integrating with RevenueCat, or contact our sales team to see how we can help.

We also work well with some no- and low-code app builders and development tools to bring RevenueCat's powerful in-app purchase features to your app, regardless of how you're building it. For more information, please check out our document on App Builders.
