Money is multiplayer. When you're building financial products, teams need to align on how funds move. Fragment used Liveblocks to build a realtime schema editor for cross-functional teams. "It's the most valuable part of the product."—Varun Mohan, CTO lblcks.io/9LehkDk

Install Liveblocks with a single prompt. We now have an “Install with AI” dropdown on our homepage. Click it and select your favourite editor to install Liveblocks automatically. If you're not using Cursor, Codex, or Claude Code, copy the prompt instead.

People are sleeping on AI in comments. Tagging agents in existing threads immediately provides all the context it needs to work effectively with humans. Here's an example where I trigger a workflow inside an @xyflow.com document.

Start AI workflows from comment threads. Using Liveblocks webhooks, you can trigger agents when an AI user is mentioned in a comment. This enables you to create complex agents that can read and edit your documents, with full context. Try it in our updated @xyflow.com example.

Many AI apps have a flaw—agents are a black box. It's frustrating when an agent edits your document, and there's no way to tell what changed. You can't trust it. And the problem only compounds with multiple agents. We can solve this with real-time presence ↓

Create multiplayer agents with realtime presence. Trigger live presence from within AI workflows, highlighting actions to connected users, and making agents real participants instead of background jobs.

Creating a multiplayer list is trickier than it looks. When two users make simultaneous edits, state drifts out of sync—you can't just use a regular array. Real-time tools like Figma and Liveblocks use a specific technique to solve this. It's called fractional indexing ↓

Add commenting and multiplayer to @handsontable.bsky.social! I've put together two demos/guides that detail how to add collaboration to your grid. The first adds multiplayer state and live presence, as you can see below.

Add collaboration to your Handsontable data grids. We've published new guides/examples detailing how to add commenting and realtime multiplayer to your table. Leave contextual info on cells, or see realtime presence as users make edits.

Interactive article: How sync engines handle realtime lists. Regular arrays don't work in multiplayer, users overwrite each other's changes. You need to use an alternate system, fractional indexing—here's how it works. Link ↓

How CRDTs and sync engines keep realtime lists ordered. An interactive guide to fractional indexing, the system powering multiplayer arrays in Figma and Liveblocks. Written by @nvie.com and @chrisnicholas.dev. Link ↓

WebSocket is the foundation for multiplayer apps. But the hard part starts right after that: concurrent edits, presence, reconnection, room lifecycle, and keeping people + AI agents in sync. lblcks.io/3izJvpp

Official n8n nodes for Liveblocks. Within @n8n.io, you can now: • Trigger workflows when Liveblocks events occur • Events include new comments, users joining rooms, more • Modify sync engine data with AI & show presence • Reply to comments with AI lblcks.io/Q5rqET5

Our documentation now natively serves markdown to agents that send the `Accept: text/markdown` header. You can also append `.md` to any URL to get the same AI-friendly format. Payloads are significantly smaller, and easier for AI to ingest.
