Liveblocks Review: Real-Time Collaboration (2026)
Liveblocks gives you the building blocks for Figma-like real-time collaboration — cursors, presence, live editing, comments, and notifications. Instead of building multiplayer infrastructure from scratch, you get APIs that handle the hard parts. Here's the review.
What Is Liveblocks?
Liveblocks is a set of APIs and React hooks for adding real-time collaboration features to web applications.
Key stats:
- React-first (with vanilla JS support)
- CRDT-based conflict resolution
- WebSocket infrastructure managed for you
- Used by companies like Notion, Figma-like apps, design tools
- Free tier: 300 monthly active users
What We Love
1. Presence (Live Cursors & Awareness)
See who's looking at what, in real-time:
import { useMyPresence, useOthers } from '@liveblocks/react';
function CollaborativeCanvas() {
const [myPresence, updateMyPresence] = useMyPresence();
const others = useOthers();
return (
<div
onPointerMove={(e) => {
updateMyPresence({ cursor: { x: e.clientX, y: e.clientY } });
}}
>
{/* Show other users' cursors */}
{others.map(({ connectionId, presence }) => (
presence.cursor && (
<Cursor
key={connectionId}
x={presence.cursor.x}
y={presence.cursor.y}
color={COLORS[connectionId % COLORS.length]}
/>
)
))}
</div>
);
}
That's it — live cursors in ~15 lines of React code.
2. Storage (Conflict-Free Shared State)
Multiple users editing the same data without conflicts:
import { useMutation, useStorage } from '@liveblocks/react';
function TaskBoard() {
const tasks = useStorage((root) => root.tasks);
const addTask = useMutation(({ storage }, title: string) => {
const tasks = storage.get('tasks');
tasks.push({ id: nanoid(), title, status: 'todo' });
}, []);
const moveTask = useMutation(({ storage }, id: string, status: string) => {
const tasks = storage.get('tasks');
const task = tasks.find((t) => t.id === id);
if (task) task.set('status', status);
}, []);
// Multiple users can add/move tasks simultaneously
// Liveblocks handles conflict resolution via CRDTs
}
3. Comments & Threads
Add Figma-style commenting to any app:
import { Thread, Composer } from '@liveblocks/react-comments';
function DocumentWithComments() {
return (
<div>
<Document />
{/* Pin comments to specific elements */}
<Thread
thread={thread}
style={{ position: 'absolute', top: thread.y, left: thread.x }}
/>
{/* Comment composer */}
<Composer />
</div>
);
}
// Built-in features:
// ✅ Threaded replies
// ✅ @mentions with autocomplete
// ✅ Emoji reactions
// ✅ Resolve/unresolve threads
// ✅ Rich text formatting
4. Notifications
Real-time notifications for collaborative events:
import { useInboxNotifications } from '@liveblocks/react';
function NotificationBell() {
const { inboxNotifications, unreadCount } = useInboxNotifications();
return (
<div>
<Bell count={unreadCount} />
{inboxNotifications.map((notification) => (
<NotificationItem key={notification.id} notification={notification} />
))}
</div>
);
}
// Auto-generated notifications for:
// - @mentions in comments
// - Replies to your threads
// - Thread resolution
// - Custom events you define
5. Yjs Integration
Works with Yjs for rich text collaboration:
import { LiveblocksYjsProvider } from '@liveblocks/yjs';
import { useRoom } from '@liveblocks/react';
import * as Y from 'yjs';
// Connect Liveblocks to any Yjs-compatible editor:
// - TipTap
// - Lexical
// - BlockNote
// - Monaco (VS Code editor)
// - CodeMirror
// Result: Google Docs-like collaborative editing
// with Liveblocks handling the infrastructure
What Could Be Better
1. React-First
React: ⚡ First-class hooks, components, great DX
Vanilla JS: ✅ Works but less ergonomic
Vue/Svelte: 🟡 Community packages, not official
Angular: 🟡 Community packages
React Native: 🟡 Partial support
2. Pricing at Scale
Free: 300 MAU
Starter: $25/mo — 1,000 MAU
Pro: $99/mo — 10,000 MAU
Enterprise: Custom
At scale (100K MAU), costs add up. Evaluate whether
self-hosting Yjs + your own WebSocket server is more
cost-effective for your use case.
3. Learning Curve
CRDT-based storage requires thinking differently about state:
Regular React state:
setState(newValue) // Simple, immediate
Liveblocks storage:
useMutation(({ storage }) => {
storage.get('key').set('field', value);
})
// More verbose, different mental model
4. Debugging
Real-time collaboration bugs are inherently harder to debug — race conditions, network partitions, and conflict resolution edge cases require specialized tooling. Liveblocks provides a DevTools panel but complex scenarios can be tricky.

Verdict
Rating: 8.5/10
Liveblocks is the most complete real-time collaboration toolkit available. The combination of presence, CRDT storage, comments, and notifications covers 90% of what you need for multiplayer apps. The React hooks are beautifully designed.
Deductions for React-first limitation, pricing at scale, and the inherent complexity of collaborative state. But if you're building a collaborative app in React, Liveblocks saves months of infrastructure work.
Try Liveblocks — the free tier (300 MAU) is enough to build and launch a collaborative feature.
