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.

How the pieces fit together

Devices join calls through a client SDK, which handles signaling, devices and call state against Stream's edge network. Your backend uses a server-side SDK to create calls, configure call types and sign the user tokens clients join with.

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.

Build with AI

Your AI agent can work with Stream from the terminal with the Stream CLI. There's also an Agent Skills pack so it can look up docs and configure your app.

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. Video apps touch these first:

Authentication and tokens

Create the user tokens your app joins calls with.

Users

Create, update, query and delete the users behind every call.

Multi-tenancy and teams

Partition one app into isolated teams.

Webhooks

React to call events from your own backend.
