TanStack Start has officially reached a v1.0 Release Candidate. This is the build we expect to ship as 1.0, pending your final feedback, docs polish, and a few last-mile fixes. Now’s the perfect time to kick the tires and help us validate the final stretch. When 1.0 ships, we’ll update this post (same URL) with any final notes.

TanStack Start isn’t just another framework, it’s the next chapter in building type-safe, high-performance React apps without the heavy abstractions. Whether you’re coming from classic SPAs or dipping into SSR, Start gives you the flexibility to scale in the direction that fits your team.

• Type-safe, file-based routing powered by TanStack Router
• Server-first ergonomics with isomorphic server functions
• Built-in streaming; React Server Components support is on the way
• URL-as-state primitives with runtime validation and full type-safety
• Great SPA and SSR DX with no lock-in or opaque magic
• Deep Query integration for prefetching, caching, and hydration

That page will stay current with the exact commands for the RC and the final 1.0.

We plan to cut 1.0 shortly after collecting RC feedback. Expect a few small RC iterations; any breaking changes will be clearly documented. As we approach stable, only light polish remains. No major API shifts.

Note: React Server Components support is in active development and will land as a non-breaking v1.x addition.

We’re fortunate to build alongside an incredible lineup of partners whose support keeps TanStack open and moving fast:

• Code Rabbit
• Cloudflare
• AG Grid
• Netlify
• Neon
• Clerk
• Convex
• Electric
• Sentry
• Prisma
• Strapi
• Unkey
• UI.dev / Bytes.dev
• Nozzle
• ...Previous Partners

Special thanks to Cloudflare and Netlify

Their collaboration is a pivotal force driving the open web forward. Explore their announcements to see how we’re building the modern web together: Cloudflare, Astro, and TanStack: building the modern web together and Supporting an Open Web with Netlify + Cloudflare.

This is the moment when your feedback matters most. Try the RC in a new or existing project and tell us what you think via the docs feedback links. If you hit an issue, the migration notes and examples in the docs will help. And we’ll be quick to respond.

Thanks for building with us. Let’s ship 1.0, together.
