Liveblocks vs Yjs (2026): Managed Collaboration vs DIY CRDT
By Alex Chen, SaaS Analyst · Updated April 11, 2026 · Based on implementation testing + developer feedback
30-Second Answer
Choose Liveblocks if you want to ship real-time collaboration in days instead of weeks — managed infrastructure, presence APIs, cursors, and comments reduce weeks of backend work to hours. Choose Yjs if you need maximum control, zero vendor dependency, and want to self-host the entire CRDT sync layer. Liveblocks wins 5-2 on developer experience, but Yjs is free forever and gives you complete control.
Our Verdict
Liveblocks
- Managed servers — no infra to run
- Built-in presence, cursors, and comments APIs
- Production-ready auth + webhooks included
- $99+/mo for production (after free tier)
- Vendor dependency and lock-in risk
- MAU-based pricing can scale up fast

Features Overview
Liveblocks handles the hard parts of real-time collaboration: server infrastructure, JWT-based auth, presence tracking, cursor sharing, comments, and Yjs-compatible storage rooms. Companies like Linear, Pitch, and Raycast use it in production. The 1-2 day implementation time (vs 1-2 weeks for DIY Yjs) is the key selling point for product teams on tight deadlines.
Pricing Breakdown (April 2026)
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | 100K MAU/mo, basic features |
| Starter | $99/mo | 500K MAU, priority support |
| Pro | Custom | Unlimited MAU, SLA, dedicated support |
Who Should Choose Liveblocks?
- Product teams wanting collaboration in days, not weeks
- SaaS apps adding multiplayer features (cursors, presence)
- Startups that want to focus on product, not infrastructure
- Teams already using Yjs who want managed hosting
Yjs
- Free and open-source — MIT license
- Battle-tested CRDT implementation
- Works with any sync provider — zero vendor lock-in
- Must build and manage sync infrastructure
- No built-in auth, presence, or cursors
- 1-2 weeks implementation vs 1-2 days
Deep dive: Yjs full analysis
Features Overview
Yjs is the most popular open-source CRDT library for building collaborative applications. Its YATA algorithm handles conflict resolution elegantly, and it works with any sync provider (y-websocket, y-webrtc, or custom). Offline support is native — documents sync automatically when reconnected. Used by companies building Notion-like and Figma-like collaborative apps at scale.
Pricing Breakdown (April 2026)
| Plan | Price | Key Features |
|---|---|---|
| Open Source | $0 | Full CRDT library, MIT license |
| Infrastructure | Your cost | WebSocket server hosting |
| y-sweet (managed) | Varies | Optional managed sync layer |
Who Should Choose Yjs?
- Teams needing complete control over sync infrastructure
- Projects where vendor lock-in is unacceptable
- High-scale apps where self-hosting is more cost-effective
- Developers who want to learn CRDT concepts deeply

Which do you use?
Who Should Choose What?
→ Choose Liveblocks if:
You want to add real-time collaboration (cursors, presence, comments, co-editing) to your app in days rather than weeks. Liveblocks handles the hard parts — infrastructure, auth, webhooks — so you focus on your product.
→ Choose Yjs if:
You need complete control over your sync infrastructure, have specific CRDT requirements, or are building at a scale where managing your own infrastructure is more cost-effective than Liveblocks' SaaS pricing.
→ Consider neither if:
You just need basic real-time updates (like a chat or notifications) — Socket.IO or Pusher are simpler. For document collaboration specifically, consider Tiptap's collaboration extension which wraps Yjs with a friendlier API.

Frequently Asked Questions
Editor's Take
I've built collaborative features with both. With Liveblocks, I had cursors and presence working in an afternoon. With Yjs, it took me a week to get the same thing running with my own WebSocket server, auth, and reconnection logic. Liveblocks saved me 40+ hours. But I've also seen the bill grow fast with MAU-based pricing — one client hit $500/mo within 3 months. If you're building something that might scale to millions of users, do the math on Yjs early.
