Overview

Liveblocks is a realtime infrastructure platform for building multiplayer apps and AI-assisted collaboration features. It is designed to handle concurrent edits on shared data so people and AI agents can work together without breaking application state.

The product combines core collaboration primitives such as presence, broadcast events, storage, threads, and feeds with developer tools for setup, authentication, documentation, examples, and API reference. The pricing page shows a Free plan for development and testing, with Pro, Team, and Enterprise tiers for production use and larger organizations.

Core capabilities

Realtime sync and conflict resolution

Liveblocks keeps shared data in sync across sessions so collaborators and AI agents can work on the same content without manual conflict handling.

Collaboration primitives

Presence, broadcast events, threads, and storage support collaborative interfaces that need live cursors, temporary signals, comments, and persisted state.

Offline support

The platform supports offline work and automatically syncs changes when users reconnect.

Multiplayer undo and redo

Each user keeps a separate undo and redo history, which is important in shared editing environments.

Developer SDK ecosystem

The documentation and API references show SDKs and components for React, React UI, Tiptap, BlockNote, React Flow, and Lexical.

Platform and operations tools

The platform includes a developer dashboard, webhooks, a WebSocket edge network, and monitoring tools for building and operating realtime features.

Common use cases

Collaborative editing
Add live cursors, selections, presence, and shared data to editors or dashboards where several people need to act on the same state at once.
AI copilots and agents
Embed AI assistants that can read shared context, make frontend actions, and participate in the same realtime room as users.
Inline comments and discussion
Build contextual comment systems with threads, emoji reactions, mentions, and notification workflows inside your own product.
Multiplayer creative tools
Ship interactive tools such as whiteboards, spreadsheets, flowcharts, or design surfaces that need low-latency sync and multi-user control.
Notifications and activity
Create an in-app inbox or activity stream with notifications, feeds, and event-driven updates that keep users informed.
