Product principles

Why TanStack?

Our libraries are built around real products and the developers shipping them

Read our product tenets

  1. Portable core

    Framework Agnostic

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

  2. Compile-time contracts

    Type-Safe by Design

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

    params.postIdstring
    query.dataProject[]
    form.emailField<string>

  3. Real workloads

    Production-Grade

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

  4. Independent tools

    No Vendor Lock-in

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