Categories:
Liveblocks provides ready-made collaboration infrastructure and components to enable real-time multiplayer editing, comments, AI agents, and notifications in web applications for developers and product teams.
🚀 Overview
Liveblocks is a collaboration engine that delivers pre-built, customizable features like comments, multiplayer cursors and editing, AI copilots, and notifications, allowing developers to integrate real-time collaboration into their apps with minimal effort.
It solves the challenge of building complex real-time collaboration infrastructure from scratch, which typically requires handling WebSockets, state synchronization (e.g., CRDTs, Yjs), offline support, undo/redo, and scalability—saving months of engineering time. Instead, teams can drop in ready-made React components and hooks.
Built for developers, product teams, and companies creating engaging products like Figma, Notion, or Google Docs. The goal is to help teams ship collaborative experiences faster, boost user engagement, drive adoption with AI features, and unlock revenue through premium collaboration tools.
✨ Key Features
- Comments: Unlimited contextual commenting with threads, reactions, mentions, and metadata for feedback and discussions.
- Multiplayer: Real-time presence, cursors, selection sharing, CRDT/Yjs storage, undo/redo, and offline support for co-editing.
- AI Agents: Collaborative AI copilots that act as users, with mentions, frontend actions, LLM integrations (Anthropic, OpenAI, Gemini), and RAG for docs/images.
- Notifications: In-app, email, Slack/Teams, webhooks with batching and user settings.
- Optional: Version history, 3D tools, whiteboards, spreadsheets; self-host dev server and sync engine (open source).
🛠 Tech Stack
- Frontend: React, Next.js, Tailwind CSS
- Backend: TypeScript/Node.js, Python (self-host server)
- Database: Custom CRDT storage, Redis-like for realtime
- Auth: OAuth (GitHub/Google), SAML SSO, MFA, RBAC
- Hosting: Liveblocks cloud (99.99% uptime), self-host option
