❤️ Open Source - creator of https://blocknotejs.org rich text editor library and https://typecell.org. Previously cofounded @Relivecc app (20M+ users).
🚀 #1 on Hacker News! 🚀 The open source and collaborative document editor we're building with the French and German governments just hit the top of HN. Proud to be part of this with BlockNote (blocknotejs.org)!

This is exactly why @ycombinator led a coalition yesterday urging @WhiteHouse support for the EU Digital Markets Act. Apple’s anti-competitive tactics hurt innovation and consumers. It’s time to free the market: LLM interoperability and real competition, not gatekeeping.
Absolutely scathing Apple Intelligence retrospective from @daringfireball "That's all she wrote. The ride is over"
big day! You should check out Livestore, new open source sync engine. Johannes started working on this years ago when we were exploring new SQLite based architectures together on the Riffle project. Since then, it’s been incredible to see him run full speed ahead with those…
After 4 years of work, I'm incredibly excited to introduce LiveStore, the next-gen data layer I'm building for Overtone. It's based on reactive SQLite and has a built-in sync engine. Give it a try - would love your feedback!
It should be easy to add Notion-like collaborative text editing. This is why we've just released first-party support for BlockNote, enabling: • Fully-hosted collaborative block-based editing • Real-time comments and notifications • Offline support, multiple editors, and more
Awesome collab (😜) with @liveblocks. Make your blocknotejs.org editor collaborative (including comments and mentions) with just a few lines of code!
Introducing… Liveblocks BlockNote. Get started with block-based collaborative editing in minutes. Our new first-party plugin for BlockNote has built-in commenting, notifications, mentions, and offline support. We've also built a Notion-style demo in our starter kit.
The Jupyter Project gets more collaborative features. JupyterCAD and JupyterGIS by @QuantStack . I'm super proud they built this with Yjs. blog.jupyter.org/real-time-coll…
Congrats! I love how you're raising the bar in terms of DX and real time collaboration - and that you've been investing more and more in open source. Even cooler to collaborate on the BlockNote integration recently; liveblocks.io/technology/col…
We just hit a big milestone—@liveblocks turned 4 🎂 In the last year: • 3× ARR • ~1M monthly collaborators • 80M+ WebSocket connections • First billboard campaign 😅 Now entering a new chapter: humans and AI collaborating together.
Thanks @agreeHQ for sponsoring this major update 🙌 thanks to your support the entire community benefits!
BlockNote + Agree = ❤️ We are strong supporters of the open-source community and have been excited to work directly with @YousefED on bringing some big features to the BlockNote community ... starting with "Advanced Tables": blocknotejs.org/docs/advanced/…
Advanced table features (split / merge / cell colors / alignment) just dropped in BlockNote! github.com/TypeCellOS/Blo…

On our way to @fosdem. Will be giving a talk on how we're collaborating @ BlockNotejs.org with EU governments to build a sovereign digital workplace: fosdem.org/2025/schedule/…. Who else is going?
Think gov tech is boring? Working on Open Source solutions for Digital Autonomy for your own country is pretty exciting 🙌 Back from Berlin where the CIOs of 🇫🇷 🇩🇪 🇳🇱 decided to keep working together on tech sovereignty through open source software. Exciting to be a small part of…


Collaborative rich text editing is one of the most popular use cases for Yjs. Today, we're releasing our BlockNote Y-Sweet demo, which get's the job done in just a few short lines of code! docs.jamsocket.com/y-sweet/tutori…
Just released BlockNote v0.20.0, with enhanced keyboard nav: - support for indenting multiple blocks - moving multiple blocks with cmd+shift+up/down (see gif) - tab through table cells --> github.com/TypeCellOS/Blo…
