   Yboard is a multiplayer desktop-like workspace based on CRDT▲165

   I've always been curious about real-time multiplayer user interfaces. When I found out about CRDTs and Yjs[1] I thought they could serve as a solid base for a project like that. So I built this pretty simple desktop-like UI (heavily inspired by lifeat.io) and used Yjs to replicate the whole UI state among multiple peers, creating the experience of a unique interface.

   Matrix-CRDT – real-time collaborative apps using Matrix as backend▲320

   Hi HN! Matrix-CRDT connects the worlds of Yjs [1] (a proven, high performance CRDT) with that of Matrix.org [2]. It started as an experiment, asking myself; can we store "state updates of a datastore" in Matrix instead of chat messages? Now, I'm convinced it's actually a really powerful combination to develop real-time, collaborative software. I'm using it for a new project and so far didn't have to write a backend yet. Matrix takes care of a lot of stuff: Authentication, E2EE, federation, hosting, etc. - so I can focus on the client. I love the ideas of Local First [3] software. Personally,…

    A collaborative pixel drawing game for when you're bored▲69

    Hello HN. This is a project me and some friends built at university in 2017. It was originally built in a rush, but we've added a few improvements over the years. It's a fun game to host at a demoparty and project on a big screen - We did that at Instanssi many times. The implementation is still rough, and suffers from the fast pace of the modern web - The frontend is likely very outdated, and the backend is built with Vapor 2 and Swift 3.1, both no longer supported. You can host this yourself, but it might be a bit of a pain to set up. The WebSocket protocol is fairly trivial to work out…

    A local-first, real-time global canvas using CRDTs▲7

    This is a demo of a family of libraries intended to make it easy to build local-first, real-time applications for mobile, desktop and the web using CRDTs. It currently has support for using Sqlite, PostgreSQL or a plain old record store (Hive) as data storage backend. https://github.com/cachapa/crdt There's also a websocket sync layer that transparently handles the connection and delta changesets between participants. https://github.com/cachapa/crdt_sync
