Typed FS Routing
Simple file-system routes with nested layouts and groups, fully typed.
Routing Modes
SPA, SSR, or SSG? One lets you choose - globally and per-page.
Loaders
Typed loaders make it easy to bring in data and migrate from other frameworks.
Web + Native
Build a website with React. Or a native app with React Native. Or both at once.
100% Vite
That's right, no more Metro. One Vite plugin, one Vite server, one port - three platforms.
The future of data
Integration with ZeroSync that makes data delightful.
Rethinking read & write
Simpler code, better UX, cross‑platform - that's the ideal. With One (and Tamagui), we're close… but there's still one huge pain point. Let's talk about data.
Native apps feel better and are easier to write thanks to having client-side databases. You can say goodbye to server boundaries, lose the glue code, mutate instantly, and things Just Work™ offline…
So, why don't we use them on the web?
Well, web needs small bundles, and has limited storage. Add in syncing, caching, joins… well, there's zero great options.
It's why we're excited to partner with Zero to include it as our recommended solution to data. Zero solves for all the above.
One is working to make Zero and other sync engines to make them work great on server and client.
