Scaling Local-First Software | Evolu

It’s not just about keeping data local; scalability touches multiple dimensions—from data volume and user count to varying authentication models, growing code complexity, developer experience, and support for diverse use cases."
🛠️ Tools & Resources
LiveStore: State management based on reactive SQLite and built-in sync engine
"Very excited to launch LiveStore in beta today after having worked on it over the past 4 years. I've built it for myself working on Overtone, an ambitious music client aiming for a native-grade high-performance app feel." See also HN discussion.
Automerge 3.0 Beta & Automerge Repo 2.0
"We’ve recently released some major updates for Automerge, the open source CRDT-based data synchronization library that we develop at Ink & Switch."
SQLite-JS Extension
"SQLite-JS is a powerful extension that brings JavaScript capabilities to SQLite. With this extension, you can create custom SQLite functions, aggregates, window functions, and collation sequences using JavaScript code, allowing for flexible and powerful data manipulation directly within your SQLite database." See also HN discussion.
Offline | Zero
"This page explains why Zero doesn't support offline writes, why it is hard for any software system to automatically support offline writes, how we recommend you handle connectivity loss, and our future plans in this area."
Feathers: Identity. Data. Realtime.
"Feathers Auth is a secure and scalable user authentication system for any framework and web runtime, even on sites with no server."
✨ Apps
DoubleMemory – more efficient local-first read-it-later app
"DoubleMemory started as an experiment to see if I can somehow automatically save all double cmd + c, as I often do instinctively, so I don't need extensions to save links and text into an app, and avoiding flooding the capture history as regular clipboard managers does." - HN discussion
Hend: Learn languages like you did when you were a kid.
"hend.world, like LingQ but local-first and with an actually usable free-tier. AI-features are completely optional." - whenwherewhatwhywho on Reddit
