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

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."

Domain-tailored CRDTs for collaboration without server involvement2018 · archagon.net · ▲158- SCSyncedStore CRDT – build multiplayer collaborative apps for React / Vue2021 · syncedstore.org · ▲144
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!
ElectricSQL, Postgres to SQLite active-active sync for local-first apps2023 · electric-sql.com · ▲617Hi HN, James, Valter, Sam and the team from ElectricSQL here. We're really excited to be sharing ElectricSQL with you today. It's an open source, local-first sync layer that can be used to build reactive, realtime, offline-capable apps directly on Postgres with two way active-active sync to SQLite (including with WASM in the browser). Electric comprises a sync layer (built with Elixir) placed in front of your Postgres database and a type safe client that allows you to bidirectionally sync data from your Postgres to local SQLite databases. This sync is CRDT-based, resilient to conflicting…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
