LoFi/31 Community Meetup

The LoFi/31 community meetup took place on Tuesday October 28th, 2025, with talks by Tim Hampson ("Local Data: Design is everything"), Pablo Mayrgundter ("Bldrs.ai: browser-based OSS CAD engine with AI integration"), and Yonatan Feleke ("Sync & Local-first Community Update").

A New Kind of Web App | Carl Assmann

"[W]hat if the local copy is the actual database? What if the client-side mutation is all we need? Those questions led me to Jazz, a true local-first database that I used to build Tilly, my open source relationship journal."

Joe and Stopa: Instant

"They founded Instant, a modern database that gives you a full backend with queries, auth, storage, real-time, and offline support, so you can build delightful apps in minutes."

🛠️ Tools & Resources

CRDT & Collaborative Editing on the Web | CascadiaJS

"You use Linear and Notion. You've read the blog posts about 'sync engines' and 'local first' software. You want that kind of product experience too, so you install some fancy CRDT libraries and expect things to Just Work™. Well, you're about to learn what we're going to discuss in this talk: that this problem is perhaps not so simple after all."

How to Build a CRUD App with TanStack Start and TanStackDB (with RxDB Integration)

"TanStackDB is a reactive data management layer which sits between your user interface and data source. It’s not like a typical ORM (Object Relational Mapper). Instead, it gives you a unified abstraction layer for working with local-first data collections which are reactive."

Eidetica: Decentralized DB

"Eidetica will allow you to write a local-first, peer-to-peer, decentralized application just by storing your data here."

Starling: Local-first reactive sync with minimal ceremony.

"A reactive and framework-agnostic data synchronization library with CRDT-like merge capabilities. Starling provides a simple way to manage, query, and synchronize application state across clients and servers with automatic conflict resolution."
