Chat SDKs overview
Build high-quality messaging experiences with chat SDKs designed for real-time performance, scalability, and fast integration — whether you’re targeting mobile, web, or cross-platform applications.
Writing your app in Swift or Kotlin? Use the headless TalkJS iOS chat SDK or Android chat SDK and build the UI yourself. Want a pre-built chat UI on mobile? Pick React Native or Flutter below. Building with Ionic? You don’t need a separate SDK, because the web chat components run inside it: see Ionic chat with TalkJS.
Ship cross-platform chat on iOS and Android with the React Native SDK. Supports push notifications, media uploads, and more.
Deliver beautiful, consistent messaging experiences across Android, iOS, and web with the Flutter SDK.
Add real-time chat to any web app with the JavaScript SDK. Customize messaging flows, enable group chats, and more.
Speed up development with ready-made components from the React SDK. Customizable and secure out of the box.
