TanStack Start in 100 Seconds

Fireship covers TanStack Start, Tanner Linsley’s full-stack React framework pitched as a type-safe, server-first alternative to Next.js.

• TanStack Start built by Tanner Linsley as a direct response to Next.js breaking changes, security vulnerabilities, and architectural complexity.
• Framework ships with SSR, streaming, server functions, and bundling out of the box.
• Default project scaffold includes Vite (VITEST), Tailwind, TanStack Router, and end-to-end TypeScript type safety.
• Server functions maintain type safety across the network, allowing safe DB/filesystem/env-var access from anywhere in the app.
• File-system-based routing via TanStack Router; loaders pre-fetch route data before render.
• API routes use the same file-route API with a server property, handling raw HTTP requests.
• Next.js critique centers on identity crisis in React itself cascading into framework instability and security issues.
