Quick Start

Stream lets you build activity feeds at scale. The largest apps on Stream have over 100 M+ users. V3 keeps that scalability while giving you more flexibility over the content shown in your feed.

What’s new in V3

For-You feed: Most modern apps combine a “For You” feed with a regular “Following” feed. V3 introduces activity selectors so 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.
Performance: 20–30 % faster flat feeds. Major speedups for aggregation and ranking, with benchmarks in the architecture guide.
SDK coverage: SDKs are available for JavaScript, React, React Native, iOS, Kotlin, Flutter, Node, Go, Python, Java, PHP, C#, and Ruby.
Activity filtering: Filter activity feeds with almost no hit to performance
Comments: Voting, ranking, 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.
Search & queries: Activity search, query activities, and query feeds endpoints.
Modern essentials: Permissions • OpenAPI spec • GDPR endpoints • realtime WebSocket events • push notifications • “own capabilities” API.
Dashboard support: Use the Stream Dashboard for app and feeds administration.
Migration tools: Migrate from V2 to V3 with the migration guide.
Activity metrics: User-engagement stats are available via activity metrics.

What is next

For-you feed improvements, including more AI-driven ranking options
See the roadmap and changelog for updates

Server side vs client side

Most API calls can be made client side
Client side API calls use the permission system. Server side API calls have full access

Most apps will default to making API calls client side, and server side do the following:

Updating feed groups or feed views for ranking and aggregation
Syncing users
Returning tokens for authenticating users
Writing to feeds that do not belong to the current user (since the user does not have access client side to do this)

Getting Started

For SDK-accurate examples generated from the OpenAPI spec, use the Stream snippets reference: TypeScript SDK - Feeds API. Replace node in the URL with the SDK language you want to inspect.

Key Concepts

Activities

Activities are the core content units in Stream Feeds. They can represent posts, photos, videos, polls, and any custom content type you define.

Feeds

Feeds are collections of activities. They can be personal feeds, timeline feeds, notification feeds, or custom feeds for your specific use case.

Real-time Updates

Stream Feeds provides real-time updates through WebSocket connections, ensuring your app stays synchronized with the latest content.

Built-in support for reactions, comments, bookmarks, and polls makes it easy to build engaging social experiences.

Common Use Cases

// Create a timeline feed
let timeline = client.feed(group: "timeline", id: "john")
try await timeline.getOrCreate()

// Add a reaction to activity
_ = try await timeline.addReaction(
    activityId: "activity_123",
    request: .init(type: "like")
)
// Add a comment to activity
_ = try await timeline.addComment(
    request: .init(
        comment: "Great post!",
        objectId: "activity_123",
        objectType: "activity"
    )
)
// Add a reaction to comment
let activity = client.activity(for: "activity_123", in: FeedId(group: "timeline", id: "john"))
try await activity.addCommentReaction(
    commentId: "comment_123",
    request: .init(type: "love")
)

val timeline = client.feed(group = "timeline", id = "john")
timeline.getOrCreate()

// Add a reaction to an activity
val addReactionResult: Result<FeedsReactionData> = timeline.addActivityReaction(
    activityId = "activity_123",
    request = AddReactionRequest(type = "like")

// Add a comment to an activity
