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,…

Hi HN, Like many of you here, this is not my first time applying to YC. Each time, my co-founder and I would copy the YC application to google docs to collaborate on it, then we copy it back to submit. This got us thinking - why can't we just collaborate on the YC application in the YC application? At one point I went down the CRDT rabbit hole and realized collaborative forms would be a great use of CRDTs, so I decided to build this out to an MVP. If you're curious about CRDTs (Conflict-Free Replicated Data Types) and how they differ from OT (Operational transformation, which is what powers…

This is an experimental extension for CRDTs, pg_crdt: GitHub repo[0]. It supports Yjs/Yrs and Automerge. The linked blog post [1] describes how we're thinking about this extension in a Supabase context. I want to emphasise this part: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."

SyncedStore is a library for building distributed, real-time collaborative web applications that sync automatically. This used to be quite complex, but with SyncedStore it's as easy as sharing a pie!

I started building this 10 months ago, largely using agentic coding tools. I've stayed very involved in the code base and architecture, and have never moved faster in my life as a dev. The word processor engine and rendering layer are all built from scratch - the only 3rd party library I used was the excellent Y.js for the CRDT stack. Would love some feedback!

Croct▲387We just launched Croct Templates, a way to drop CMS-powered components into your app with a single command. It's like Shadcn, but for CMS, AB testing and personalization: * Built-in support for A/B testing, content editing, and dynamic logic * Works with existing projects (Next.js, React, etc.) * Supports community libraries via `npm://`, `shadcn-ui://`, etc. Example: ```bash npx croct@latest use shadcn-ui://block/pricing-page ``` Happy to answer any questions!

Hi! I’m one of the founders of s2.dev, and recently have been hacking on opbox, which is an open-source daemon that turns directories of text files (code, markdown, etc) into collaborative, multi-player workspaces. This started as a bit of an intellectual curiosity, to see if it was possible to do real-time sync at the filesystem level (i.e., in an editor-agnostic way). The idea is pretty simple: - Opbox workspaces are roughly analogous to git repositories (and can be used alongside existing git repos, to share live changes between commits) - When the opbox daemon is running in a workspace…

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
