TanStack Start Hits 1.0, and Netlify Makes It the Agent Default TanStack Start reached version 1.0 on Oct. 13, 2026, and Netlify made it the default framework for new Agent Runners projects the same day, according to a Netlify changelog entry. TanStack maintainer Tanner Linsley wrote in the 1.0 announcement that Start is "finally stable" and that 1.0 commits to the framework's APIs, while Netlify shipped the @netlify/vite-plugin-tanstack-start plugin so existing apps can add a plugin, a netlify() line in vite.config.ts and a netlify.toml with a vite build command and dist/client publish directory. Netlify's plugin also emulates serverless and edge functions, Blobs, Netlify Database, the Cache API, Image CDN, redirects, headers, environment variables and AI Gateway in the dev server without the Netlify CLI, and TanStack lists Netlify, Render, Railway, Vercel and Cloudflare as hosts for Start. TanStack Start Hits 1.0, and Netlify Makes It the Agent Default TanStack Start went stable Oct. 13. Netlify said new Agent Runners projects now default to it and shipped a Vite plugin for existing apps. TanStack Start reached 1.0 on Oct. 13. Netlify made it the default framework for new Agent Runners projects the same day, the company said in an Oct. 13, 2026 changelog entry https://www.netlify.com/changelog/2026-10-13-tanstack-start-1-0/ . What changed TanStack maintainer Tanner Linsley wrote in the 1.0 announcement that Start is “finally stable” and ready for production. He described 1.0 as a commitment to the framework’s APIs. The core application model should not change under developers who adopt it. Netlify said Start apps deploy on its platform with server-side rendering, server routes, server functions and middleware running on Netlify Functions. Projects created in Agent Runners, its AI app builder, now use Start 1.0 unless another framework is specified. For existing apps, Netlify’s steps: - Install @netlify/vite-plugin-tanstack-start as a dev dependency. - Add netlify after tanstackStart in vite.config.ts . - Add a netlify.toml with the build command vite build and the publish directory dist/client . New apps can start from npx create-tsrouter-app@latest --template file-router --add-ons tanchat,netlify . The plugin also emulates Netlify inside the dev server, Netlify said. That covers serverless and edge functions, Blobs, Netlify Database, the Cache API, Image CDN, redirects, headers, environment variables and AI Gateway, with no Netlify CLI required. Not a Netlify exclusive TanStack’s announcement lists Netlify, Render, Railway, Vercel and Cloudflare as places to run Start. It credits Netlify with backing Start’s development. Linsley’s post credits Vite and Nitro with separating build tooling from hosting. That split lets one framework target all five hosts. Key Takeaways - TanStack Start is stable as of Oct. 13, 2026. - New Netlify Agent Runners projects default to it. - Existing apps add a plugin, a config line and a netlify.toml . The Take Defaults shape what gets built. An AI app builder that scaffolds Start by default will put many first-time apps on TanStack’s router, and on Netlify’s functions. That is a distribution win for Netlify more than a technical one. Start also runs on four other hosts. The local emulation is the practical part. A dev server that mimics Blobs, the database and AI Gateway removes a reason to deploy just to test.
