What is Stream?

Stream allows developers to rapidly deploy scalable feeds, chat messaging and video with an industry leading 99.999% uptime SLA guarantee.

Stream's Activity Feed V3 SDK enables teams of all sizes to build scalable activity feeds. The best place to get started is to follow the tutorial.

Build with AI Agents

If you build with an AI coding agent, our agent skills teach it how to use this SDK correctly. Install them once:

curl -fsSL https://getstream.io/cli.sh | bash
getstream init

Then reach for the /stream-react skill:

/stream-react scaffold a Next.js app with a following feed and an activity composer
/stream-react add a notification feed to my existing React app

It can scaffold a new Next.js app with the SDK wired up, add Feeds to an app you already have, audit an existing integration, or migrate between SDK major versions. Works with Claude Code, Cursor, Codex, and any other agent that reads the universal .agents location.

👩‍💻 Free for Makers 👨‍💻

Stream is free for most side and hobby projects. To qualify, your project/company needs to have < 5 team members and < $10k in monthly revenue. Makers get $100 in monthly credit for feeds for free.

💡 Supported Features 💡

Here are some of the features we support:

• For-You feed: Most modern apps combine a “For You” feed with a regular “Following” feed. With activity selectors you can:
  • surface popular activities
  • show activities near the user
  • match activities to a user’s interests
  • mix-and-match these selectors to build an engaging personalized feed.
• Comments: Voting, threading, images, URL previews, @mentions & notifications. Basically all the features of Reddit style commenting systems.
• Advanced feed features: Activity expiration • visibility controls • feed visibility levels • feed members • bookmarking • follow-approval flow • stories support.
• Activity filtering: Filter activity feeds with almost no hit to performance
• Search & queries: Activity search, query activities, and query feeds endpoints.
