TanStack
ELI5 — The Vibe Check
TanStack is Tanner Linsley's empire of framework-agnostic tools. Query, Table, Router, Form, Virtual - all headless, all powerful, all working in React, Vue, Solid, or Svelte. It's like a Swiss Army knife that doesn't care which hand you hold it with.
Real Talk
TanStack is a collection of high-quality, framework-agnostic TypeScript libraries including Query (data fetching), Table (headless tables), Router (type-safe routing), Form (form management), and Virtual (virtualization). Each library provides headless logic with adapters for major frameworks.
