Headless, type-safe, composable tools for building modern web applications that work naturally for developers and reliably for agents
Principles
Our libraries are built around real products and the developers shipping them.
Portable core
Our library cores are provider-agnostic and logic-driven, meaning you can use the same logic in React, Vue, Svelte, Solid, and more.
Compile-time contracts
Built with TypeScript from the ground up, providing incredible autocomplete and safety across your entire data-fetching and state management stack.
Real workloads
Battle-tested in the world's largest apps. We build for scale, handling complex concurrency, caching, and state synchronization with ease.
Independent tools
Open source and independent. We aren't beholden to any single cloud provider or framework team, ensuring the best tools for the community.
Sponsors get special perks like private discord channels, priority issue requests, and direct support!
TanStack has a new logo, a design system, and a brand that finally looks like actual people care about the details, because we do.

TanStack Markdown and TanStack Highlight are two tiny, synchronous libraries for turning technical content into deterministic, themeable webpages without shipping a general-purpose publishing system.
React Server Components solved a real performance problem for tanstack.com, but once our markdown and highlighting stack got small, we were left with a set of runtime and code-shape tradeoffs we didn't want anymore.
