DX in @liveblocks.io is crazy! See this hook? It fetches a multiplayer list of objects. Every time the list changes, it automatically updates with a new value, in real-time. No back-end or setting up WebSockets—just React.

Test your Liveblocks app locally using our dev server. Open-sourced earlier this year, we've continued to make improvements, such as enabling more REST APIs, permissions, and room metadata. $ npx liveblocks dev

In case you missed it, @liveblocks.io has nodes for n8n! It's super handy for setting up complex workflows, for example after a Liveblocks comment's created, you can trigger an AI response. Another use case is allowing AI to modify your realtime data with a custom trigger.

Did you see? Liveblocks has @n8n.io nodes. • Trigger workflows from webhook events. • Edit realtime data, send AI comments, more. All possible without writing code.

Build an agent-powered spreadsheet. Our new open-source example shows how to enable human-agent collaboration inside a @nextjs.org app, featuring multiplayer cells, chat, comments, and more. Try it ↓

We're transitioning into a world where multiplayer documents are required. As more and more agents become commonplace, you need a way to ensure that their modifications don't disrupt other agents & humans—you need a sync engine, like below. And that's not the only challenge ↓

Add WebSockets to your agent/workflow with one React hook! Feeds is a new real-time primitive for the agentic world, by @liveblocks.io. Use it to send live JSON data into your app, directly from your back-end. Status updates, chat messages, tool calls, etc. And it's multiplayer.

Do you know we have a @xyflow.com package? Add multiplayer editing into your flowchart in just a few lines of code.

Lyster brought realtime, multiplayer editing to enterprise architecture. "We didn’t want to become Yjs WebSocket experts. We wanted to just focus on building the product. Liveblocks was the fastest path to getting this on the market." — Sam Lindemer, CEO Learn how they did it ↓

Add collaborative .docx editing to your app in 5 mins! @superdoc.dev 🤝 @liveblocks.io

The best apps, like Linear & Notion, increasingly feature AI that inhabits the same space as humans. In particular, agents that can: • Edit documents. • Show live presence. • Leave comments in threads. I've written a post on how to add it to your own app!

What the future of productivity apps looks like. The next generation of apps are becoming shared spaces where people and AI agents work together in realtime—live presence, conflict-free editing, and comments. Add these features to your app now ↓ lblcks.io/4b9TLPC

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 ↓
