# Video and Audio Stream Video runs video calling, audio rooms and livestreaming on Stream's global edge network. The SDKs manage devices, call state and participant tracks; the same API scales from one-to-one calls to streams with millions of viewers. ## SDKs ### Client Side SDKs Everything a device needs to join a call: signaling, device management and rendering, plus prebuilt call UI on the app platforms. - [React](https://getstream.io/video/docs/react/): Components and hooks for web calling UIs. - [iOS](https://getstream.io/video/docs/ios/): SwiftUI components for calling UIs. - [Android](https://getstream.io/video/docs/android/): Compose components for calling UIs. - [React Native](https://getstream.io/video/docs/react-native/): Native calling UI from one codebase. - [Flutter](https://getstream.io/video/docs/flutter/): Widgets for calling UIs. - [JavaScript](https://getstream.io/video/docs/javascript/): The core browser client, with the UI left to you. - [Unity](https://getstream.io/video/docs/unity/): Video calls inside Unity games. - [ESP32](https://getstream.io/video/docs/esp32/): Calling on embedded hardware. ### Backend Create calls, mint tokens and configure call types from your server. One docs set covers all seven server languages with language tabs; Vision Agents is a separate framework for putting real-time AI agents in calls. - [Server SDKs](https://getstream.io/video/docs/api/) - [REST](https://getstream.github.io/protocol/?urls.primaryName=Video) - [Vision Agents](https://visionagents.ai) ## Build with AI Your AI agent can work with Stream from the terminal with the [Stream CLI](https://getstream.io/cli/docs/). There's also an [Agent Skills](https://getstream.io/agent-skills/docs/) pack so it can look up docs and configure your app. ```bash curl -fsSL https://getstream.io/cli.sh | bash getstream skills ``` - [Agent Skills](https://getstream.io/agent-skills/docs/) - [Stream CLI](https://getstream.io/cli/docs/) ## Platform Users, auth and the rest of the account-level machinery work the same in every Stream product, so they are documented once in the [platform docs](https://getstream.io/docs/platform/). Video apps touch these first: - [Authentication and tokens](https://getstream.io/docs/platform/authentication/): Create the user tokens your app joins calls with. - [Users](https://getstream.io/docs/platform/users/): Create, update, query and delete the users behind every call. - [Multi-tenancy and teams](https://getstream.io/docs/platform/multi-tenancy/): Partition one app into isolated teams. - [Webhooks](https://getstream.io/docs/platform/webhooks/): React to call events from your own backend. - [Rate limits](https://getstream.io/docs/platform/rate-limits/): How limits work and how to handle 429 responses. ## Start here Pick your platform and use case; each tutorial ends with a working app. ### Video calling - [React](https://getstream.io/video/sdk/react/tutorial/video-calling/) - [iOS](https://getstream.io/video/sdk/ios/tutorial/video-calling/) - [Android](https://getstream.io/video/sdk/android/tutorial/video-calling/) - [React Native](https://getstream.io/video/sdk/react-native/tutorial/video-calling/) - [Flutter](https://getstream.io/video/sdk/flutter/tutorial/video-calling/) - [JavaScript](https://getstream.io/video/sdk/javascript/tutorial/video-calling/) - [Unity](https://getstream.io/video/sdk/unity/tutorial/video-calling/) ### Audio rooms - [React](https://getstream.io/video/sdk/react/tutorial/audio-room/) - [iOS](https://getstream.io/video/sdk/ios/tutorial/audio-room/) - [Android](https://getstream.io/video/sdk/android/tutorial/audio-room/) - [React Native](https://getstream.io/video/sdk/react-native/tutorial/audio-room/) - [Flutter](https://getstream.io/video/sdk/flutter/tutorial/audio-room/) - [JavaScript](https://getstream.io/video/sdk/javascript/tutorial/audio-room/) ### Livestreaming - [React](https://getstream.io/video/sdk/react/tutorial/livestreaming/) - [iOS](https://getstream.io/video/sdk/ios/tutorial/livestreaming/) - [Android](https://getstream.io/video/sdk/android/tutorial/livestreaming/) - [React Native](https://getstream.io/video/sdk/react-native/tutorial/livestreaming/) - [Flutter](https://getstream.io/video/sdk/flutter/tutorial/livestreaming/) - [JavaScript](https://getstream.io/video/sdk/javascript/tutorial/livestreaming/) ## FAQ **Are calls, audio rooms and livestreams different APIs?** No. Each is a call with a different [call type](https://getstream.io/video/docs/api/call-types/builtin/); the SDKs and API are the same. **How many viewers can a livestream have?** Millions. Viewers watch over WebRTC or [HLS](https://getstream.io/video/docs/api/streaming/overview/). **Can I stream from OBS?** Yes. Livestreams accept [RTMP](https://getstream.io/video/docs/api/streaming/rtmp/), WHIP and SRT input. **Can calls be recorded and transcribed?** Yes. [Recording](https://getstream.io/video/docs/api/recording/introduction/) and [transcription](https://getstream.io/video/docs/api/transcribing/calls/) are built into the API. **Do I need my own backend?** Yes. Your server signs the [user tokens](https://getstream.io/docs/platform/authentication/) devices join calls with. **Can an AI agent join a call?** Yes. [Vision Agents](https://visionagents.ai) puts real-time AI agents into calls. **Can I read these docs as markdown?** Append `.md` to any page URL. [/llms.txt](https://getstream.io/llms.txt) indexes every page. --- For the most recent version of this documentation, visit [https://getstream.io/video/docs/](https://getstream.io/video/docs/).
