Trying out @nextjs.org 3.16 instant navigations. Adds a noticeable feeling of snappiness 👏 nice. Here's a before → after.

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.

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.

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 ↓

I'm building an AI-powered spreadsheet template! AI can edit cell contents, styling, and leave comments. Plus the whole table is multiplayer, so that humans and AI can work together at the same time. Interested in me open-sourcing it?

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

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.

Building multi-agent canvases in a morning with @liveblocks.io & @tldraw.com 👏 • Humans and AI have live presence. • Both can make changes simultaneously. • Trigger any amount of agents at once.

Everything we shipped at @liveblocks.io in May! 1️⃣ New guides for enabling AI in @xyflow.com flowcharts. Trigger real-time agent workflows from comment pins, and AI will make sync engine changes as you watch. More ↓

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!

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

We've deployed our slides demo. Collaborate with agents and humans in this Liveblocks-powered example. → lblcks.io/slides-demo

Add real-time presence to your agent in 5 mins! With a couple of React hooks and REST APIs, you can add WebSockets to your AI, without setting up any servers or infrastructure. Plus updates are multiplayer—all users see changes as they come. Set it up ↓

I now write agent skills for everything I do at work. Not just generic skills, but highly specific custom skills, with a singular purpose. At this point, it saves me hours of tedious work every week. Do it yourself ↓

This is what you can build with Liveblocks. AI-powered apps with multiplayer documents, realtime presence, activity feeds, and comment threads. Our new slideshow demo showcases what’s possible in modern collaborative apps. Learn more ↓

I've added an "Install with AI" button to our homepage. One click opens Cursor, Codex, or Claude Code and starts a new chat with the installer prompt—there's no quicker way to get started! It loads our agent skills too.

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.

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 ↓

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 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.

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.

Today, I co-blogged and got to see @chrisnicholas.dev’s amazing visualization talents up close! 🤩 lblcks.io/W1Ehpn6

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 ↓

Edit multiplayer React Flow state from the server! We've just released a @liveblocks.io API for this, meaning you can easily make server-side AI changes to your @xyflow.com app. $ npx liveblocks upgrade
