🚨 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.

Give it a spin. Tell us what breaks. 🚀

We’re beyond excited to partner with TanStack on this.

We believe TanStack DB can be the reactive data core for the next generation of fullstack apps.

Live queries. Mutations that feel like transactions. State that syncs and reacts.

It’s backend-agnostic and incrementally adoptable:
✅ Works with REST, GraphQL, sync engines, polling
✅ Built on TanStack Store
✅ Pairs seamlessly with TanStack Query

You can start with just a collection or two — no full rewrite needed.

Think of it as TanStack Query meets client-side database — perfect for local-first, collaborative, or offline-friendly apps.

Live queries. Mutations that feel like transactions. State that syncs and reacts.

TanStack DB gives you:
🔁 Collections with live queries
⚡️ Sub-millisecond incremental updates (via differential dataflow!)
🧠 Fine-grained reactivity for minimal re-renders
🛠 Robust optimistic transactions with sync lifecycle support
🧱 Normalized data by default

wow this is huge!!! so pumped to dive into this later/when i get time and congrats on the launch

Yooooo this is sick. Just started playing around with TanStack Start and this seems like a great fit for the small project I was gonna build.
