24 alternatives to Collaborate on your YC Application with CRDT-powered forms
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…
Together Form is a collaborative application platform using CRDT technology to enable real-time co-editing of forms without copying between tools.

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,…

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."

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.

NoteCove▲82I built NoteCove because I wanted notes and tasks that sync across devices without the data going to a SaaS company. The sync works through files on your own iCloud Drive, Google Drive, or Dropbox — there's no NoteCove server in the sync path. The tricky part was making this reliable. I ended up using CRDTs (specifically Yjs) for conflict resolution, which handles the case where you edit the same note on your phone offline and your laptop offline — both edits merge without losing either. It has a full task management system alongside notes: custom states, kanban boards, parent/child…

Hi HN! I'm Philip, one of the founders of Tiptap. Next to our open-source rich text editor framework, we started developing Hocuspocus about five years ago and open-sourced it too, to solve one of our biggest challenges back then: real-time collaboration in web editors. We found Yjs by Kevin Jahns, a CRDT library that handles concurrent edits without conflicts. Basically, Yjs merges changes from users without conflicts and in real-time. Hocuspocus is the WebSocket server built on top of Yjs. It handles real-time sync, presence/awareness, persistence, and Redis-based scaling. While we…

Hey HN, I want to share with you something I and my four colleagues have been working on for the last several years. It’s a whiteboarding and notes tool called Muse[1]. We just released a 2.0 version which includes local-first sync. A little backstory: I’m one of the authors of the 2019 essay Local-first software[2]. (Past HN discussions[3][4].) The thesis is to reclaim some of the ownership over our data that we’ve lost in the transition from filesystems to cloud/SaaS. So I’m excited to bring CRDT technology “out of the lab” and into a commercial product as a chance to prove the value…
