Adapty SDK is an open-source framework that makes implementing in-app subscriptions in Kotlin Multiplatform fast and easy. It’s 100% open-source, native and lightweight.

• No server code implementation. Integrate in-app purchases with server-side receipt validation in minutes — in your own paywall or one created in the no-code builder.
• No-code paywall builder. Create a beautiful, natively rendered paywall in the no-code editor and display it in your app to start getting paid instantly.
• On-the-fly paywalls price testing. Test different prices, duration, offers, messages, and designs simultaneously, all without new app releases.
• Beautiful onboardings. Design onboardings in the no-code editor and guide users through their first app experience.
• Full customer's payment history. Explore the user's payment events from the trial start to subscription cancellation or billing issues.
• 3rd-party integrations. Send subscription events to 3rd-party analytics, attribution, and ad services with no coding, even if the user uninstalls the app.
• Advanced analytics. Analyze your app real-time metrics with advanced filters, such as Ad network, Ad campaign, country, A/B test, etc.

Adapty handles everything, from free trials to refunds, in a simple, developer-friendly SDK.

• Free trials, upgrades, downgrades, crossgrades, family sharing, renewals, promo offers, intro offers, promo codes, and more – Adapty SDK does everything with a single line of code.
• Easy subscription management.
• One-time purchases and lifetime subscriptions supported.
• Sync subscribers' states across iOS, Android, and Web.

With Adapty, you can create a complete, purchase-ready paywall in the no-code builder.

Adapty automatically renders it and handles all the complex purchase flow, receipt validation, and subscription management behind the scenes.

• Optimize in-app subscriptions with the paywall A/B testing. Conversions, trials, revenue, cancellations, and more — everything is calculated for you: each paywall and each A/B test.
• Change images, colors, layouts, and literally anything using the no-code builder or a custom JSON. Configure different prices, trial periods, promo offers, and more in Adapty without app releases.

• Manage the subscription's state without managing transactions.
• 99.5% accuracy.
• View and analyze data by attributes, such as status, channels, campaigns, and more.
• Filter, group, and measure metrics by attribution, platform, custom users' segments, and more in a few clicks.
