🚨 Big news! We’ve been collaborating with the legendary Tanner Linsley and the TanStack team to build something new: TanStack DB — a reactive, normalized, transactional state engine that extends TanStack Query.

Working with your database locally, while you're building, needs to be simple. 🙌 Prisma 6.8.0 just landed: ✅ Local Prisma Postgres (Early Access) ✅ VS Code Agent mode support ✅ Native Deno support ...& more 👉 pris.ly/6.8-blog?utm_s…

Excited to share the first version of BlockNote AI! Connect any model, customize prompts, and interact with AI just like you would with a human teammate. The user stays in control — accepting, rejecting, or refining suggestions.

Berlin in May is such a nice city for hosting Local-First Conf.

Introducing TanStack DB James Arthur 🦋 with a great presentation introducing a new front end TANSTACK library to help progressively adopt sync in any app, with any backend.

Interested in building on sync? In London or SF? Come along to Sync London on July 1st lu.ma/sync-london -- we're co-organising with Anselm Eickhoff and Yonatan, great speakers including Peter Coppinger 🇺🇦 and Matt – Trigger.dev Early-bird tickets and CFP both still open for Sync Conf in

Postgres running natively in Bolt 🔥 Great work by ElectricSQL team & pglite- this is huge!! Y’all won’t need to spin up hosted databases for building soon… 👀

The main obstacle to sync is it's a new black box. Is it reliable/fast enough to drive critical data flows? People rightfully have a db-level quality bar. If it seems like ElectricSQL has been quiet lately, it's because we're 100% focused on meeting this bar.

Building apps on Postgres? Here how to do it using sync: youtu.be/mDzzK5-XkZ8?t=…

PGlite (WASM Postgres) now gets over 1 million downloads a week! 🤯🚀 Absolutely incredible to see how people have embraced what we have built. Awesome work by the team!

A big update to our Electric/TanStack DB starter — it's now a project app, not just a todo app! You can create projects & share them with other users.

New docs for the TANSTACK DB live query api 🚀 We completed a major refactor/rewrite of both the query builder and query engine a couple of weeks ago, and the docs are now live - link in 🧵 Live queries use IVM* to do the minimal work on each change.

Tanstack DB is a reactive client store for building super fast apps on sync. Based on a TypeScript implementation of differential dataflow, it's type-safe, declarative, incrementally adoptable and insanely fast 🔥

TanStack DB is an extremely gratifying realization of the years-long vision I had for React Query from day 1. To be honest, most of us wouldn't have been ready for sync back then and many still aren't, which is exactly why Query exists today, as an incrementally adoptable tool

A shoutout to the incredible team behind ElectricSQL.

Loving this flow to upgrade my apps Tanner Linsley James Arthur 🦋 TANSTACK

TanStack DB with Sync provides an exciting new way to add end-to-end reactivity to your web applications, including optimistic UI updates. 🧵

And you can create shapes directly form the dashboard too! Try sync with zero lines of code.

Agentic AI, beneath all the hype, is actually just normal software. You can build agentic systems with a database, standard web tooling and real-time sync.

That's 168ms -> 1.6ms! and we have a lot of good ideas how to make it even faster.
