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…

In plain words
Together Form is a collaborative application platform using CRDT technology to enable real-time co-editing of forms without copying between tools. Built specifically to address the friction of YC application collaboration, it allows co-founders to work simultaneously on form submissions with automatic conflict resolution. The tool uses Conflict-Free Replicated Data Types instead of traditional operational transformation, eliminating the need for a central server to merge concurrent edits while ensuring all users reach the same final state automatically.

Matrix-CRDT – real-time collaborative apps using Matrix as backend2022 · github.com · ▲320Hi 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,…

Pg_CRDT – an experimental CRDT extension for Postgres2022 · supabase.com · ▲296This 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."

Yboard is a multiplayer desktop-like workspace based on CRDT2022 · github.com · ▲165I'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.
