# Gravix Cloud

> Gravix Cloud adds real-time voice calls, video calls, live audio rooms and live streaming to apps. SDKs: Flutter (`gravix_rtc` on pub.dev, for Android and iOS apps) and Web (`gravix-rtc` on npm, TypeScript). The app joins a room with a short-lived access token that the developer's own server signs with the App ID and App Certificate. The App Certificate never goes into an app.

Rules for AI coding assistants:

- Flutter: `flutter pub add gravix_rtc`, then `import 'package:gravix_rtc/gravix_rtc.dart';`. Main class: `GravixRoomService`.
- Web and React: `npm install gravix-rtc`, then `import { Room, RoomEvent, GravixTokenProvider, connectWithTokenProvider } from 'gravix-rtc';`.
- Server: `npm install gravix-rtc-token` (Node 18+, Deno, Bun, edge runtimes) or `gravix-token-go` (Go 1.21+). Sign tokens only on the server.
- The SDKs POST `{ room, identity, name, can_publish }` to your token endpoint and expect `{ token, url }` back. The server decides identity and publish rights.
- Android and iOS apps use the Flutter SDK. There is no separate native Kotlin or Swift SDK.
- Use only the APIs in these docs. Docs were checked against gravix_rtc 0.4.13 and gravix-rtc 0.6.6.
