CRDTs replicate data so edits merge cleanly without conflicts.

I hadn't ever thought of having each device write its own database / file to a synced folder, and then just periodically having each device read all the other files to accumulate a fully synced state 🤔 via: https://github.com/tonsky/crdt-filesync #datasync #crdt

Build local-first and decentralized apps - Based on CRDTs, NextGraph brings about the convergence between P2P and Semantic Web, towards a secure and privacy-preserving cloud
https://nextgraph.org/

(I vaguely remember that some people I know worked on a CRDT lib (while at mozilla maybe?)... but I always struggle to remember its name... help me please if you're one of those :)

NextGraph - Decentralized, encrypted and local-first platform and framework, towards the better internet we all deserve!

Features a social network, shared documents, productivity tools, an app store, and more! You can use NextGraph for free : resilient, secure, private and encrypted. You own your data and software! Developers can build new web3.0 local-first apps with our open source framework, based on open standards, with CRDTs, E2EE, Linked Data, JSON, Markdown...

When reading Greg's explainers I have always wished I could animate them. Despite a lifetime in software my brain doesn't translate Python code expressing a CRDT algorithm into a machine I can see advance step by step. Looks like that wish is coming true.

The first Local-First Devroom at #FOSDEM was a true gem.

Psyched about the potential and the magic of this insanely cool stuff.

Also: very very sweet humans behind this.

Thanks @localfirst

Cool blog post (https://www.palanikannan.com/blogs/local-first-in-production-fosdem-2026-recap) by @palanikannan about applying #yjs to production! (there is also a 5-part series about yjs on his blog).
The video of the corresponding #fosdem talk should be available in the following days (https://fosdem.org/2026/schedule/event/TCH8XQ-plane-wiki-local-first-in-production-with-yjs/).
