Why TanStack?

Our libraries are built on principles that put developers first

Framework Agnostic

Every library starts with a provider-agnostic core. Use React, Vue, Solid, Angular, or vanilla JS—your choice.

Type-Safe by Design

First-class TypeScript support that catches bugs at compile time and makes refactoring fearless.

Production-Grade

Battle-tested in the world's largest apps. Built for real workloads, not just happy-path demos.

No Vendor Lock-in

Open source and independent. No hidden agendas, no platform bias—just great tools for developers.
