Shout-out to @marcbouchenoire.com for building these tidy components!
We've just released new React components!
Build a collaborative app with @liveblocks.io using customisable avatar stack, cursors, and commenting components. We've written a blog post that takes you through what they are, and how to use them.

And a decoders ↔ zod comparison, you can see how easy it is to read!
![Decoding error:

^^^^^^^^^^^^ Must be Date
tags: ["foo", "bar"],

$ npm install decoders

Here's an example of one of those error messages.
import { array, iso8601, … } from "decoders"; const userDecoder = object({ id: number, name: string, createdAt: optional(iso8601), tags: array(string), });
Zod isn't the only option.
Our team uses decoders, built by the wonderful @nvie.com. We find it's:
• Easier to read, as it looks like TypeScript.
• Quicker to debug, with its human-readable error messages.
• Lighter to ship, with tree-shaking and smaller bundles.

Fantastic!
Introducing Zen Router: our open-source HTTP router.
Zen Router handles billions of requests per month at Liveblocks, and today we're open sourcing it. Initially designed for Cloudflare Workers, but also compatible with Node.js, Bun, and more.

Shout-out to Fumadocs, which made this all possible so quickly. A fantastic project.

I've built a full docs site in a day with @nvie.com!
We've just open-sourced the HTTP router that's handles billions of requests per month at Liveblocks. Our team built it with Cloudflare Workers in mind, but it supports other runtimes too. Opinionated, type-safe, Zen.

Article: Which JavaScript rich-text editor is best?
Tiptap, BlockNote, Lexical, more—a deep-dive into all the options. Our team's uniquely positioned to give guidance on this, as we've used them all at work. Written last year, still up to date!

It's open source, so feel free to have a play with it!

Also, check out the multiplayer apps it features—Tiptap, tldraw, BlockNote, and a custom starting point for your own whiteboard.
In a new addition to the @liveblocks.io starter kit, it now fully supports multiple workspaces, each which its own inbox.
You can see how they're different when you switch.
I've set up a whole collaborative app template for Next.js!
Along with multiplayer apps, it's got live permissions:
• The document immediately appears when shared.
• When edit access is given, the page auto-reloads.
• The user can then make real-time changes.

Build multi-tenant collaborative apps with Organizations.
When building with Liveblocks, you can define a user's organization, and all resources will be automatically compartmentalized—rooms, threads, notification, etc.
Below, you can see a different inbox in each workspace.
In future, we'll be opening up even more of our product—Comments, Notifications, AI Agents. The dev server doesn't support these yet, but they will be coming. Very excited to see where this goes!
Learn more in our blog post.

You need to make a couple edits to your app to connect to the dev server, but we provide an AI prompt that will make all these changes for you, setting up an environment variable toggle.
You can use this to set up automated CI or E2E testing.
Liveblocks is going open-source!
Today we've opened up the sync engine server that powers Liveblocks Storage and Yjs on our platform. We've also built a local dev server for testing your @liveblocks.io app locally, try it in your app now:
$ npx liveblocks dev
Such a strange day for you 😂.
All your work on this has been amazing!
My plan for today: announce that we're open sourcing the Liveblocks server! 🎉
The internet's plan for today: continvoucly morging my mentions 😂
Anyway, here's what I actually wanted to share today:
We've open sourced our sync engine and dev server.
Starting today, you can run and test your multiplayer applications locally using our new server package and CLI. Additionally, this marks a shift towards an open-source Liveblocks.

Liveblocks docs now support markdown—just add `.md` to any URL.
Agents can also request markdown using the `text/markdown` header.
Result? The homepage goes from 327kb → 6kb.
I just asked it clone X, and it nailed it first try!
