Adapty: CRM for mobile apps with subscriptions

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

Why Adapty?

• No server code implementation. Integrate in-app purchases with server-side receipt validation in minutes — in your own paywall or using the no-code flow builder.
• No-code flow builder. Create beautiful, natively rendered single- or multi-screen flows in the no-code editor and display them in your app. With flows, you can start getting paid instantly or implement engaging onboardings in your app.
• On-the-fly paywalls price testing. Test different prices, duration, offers, messages, and designs simultaneously, all without new app releases.
• 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.

Integrate IAPs within a few hours without server coding

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.

Design flows in the no-code Flow Builder

No-code Flow Builder

With the Adapty Flow Builder, you can visually design complete user experiences — from single-screen paywalls to multi-step onboardings, surveys, and quizzes.

• Flexible customizable flows: Build any kind of flow: a single-screen paywall, a multi-step sequence, a survey, or anything in between.
• Native rendering: The Adapty SDK renders flows natively without web views to ensure a seamless user experience.
• Update without redeploying: Change copy, design, pricing, or logic any time. Updates reach your users without an app release.

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

Test paywalls & prices on Flutter without app releases

Adapty: In-app subscriptions with paywall A/B testing

• 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.

Real-time analytics for your Flutter app

Adapty: How Adapty works

• 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.

Requirements

Requirement	Minimum
Flutter	3.32.0
Dart	3.8.0
iOS	15.0
Xcode	26.0
Android	API 21 (Android 5.0)

iOS uses Swift Package Manager. As of 4.0.0 the iOS native SDK is distributed via Swift Package Manager only (CocoaPods support was dropped). On Flutter 3.44+ SwiftPM is enabled by default and the plugin works out of the box. On Flutter 3.32–3.43 you must enable it once per project before building for iOS:

flutter config --enable-swift-package-manager
