TanStack Query
MIT server-state cache for async data (React Query lineage)
Libraries / Data Fetching · OSS/MIT · 47k
What's Good
MIT. Declarative fetch/cache/invalidate for React, Vue, Solid, Svelte, Angular. Devtools, optimistic updates, infinite queries. De-facto async server-state default outside full RSC frameworks.
The Catch
Server-state cache library; not SaaS. Not a global client store (that is Zustand/Redux). Not tRPC itself — pairs with it. You still own the API and auth.
Verdict
MIT server-state cache. Free library; not a BaaS.
