TanStack
Type-safe headless libraries for queries, tables, routing and forms.
NOT REALLY
why this verdict
Keep it — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the dev tools job, so this one is still worth keeping open.
- A named launch, not a vibe named, unlinked
- Frameworks bundle their own data fetching and routing. Anthropic, January 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 2 of 2 listed replacements have a usable free tier: SWR and RTK Query.
- What the call is worth nothing to cancel
- No paid entry tier tracked, so there is no subscription to cancel.

The backstory
TanStack Query is in a large share of React apps, generated or otherwise, because server-state caching is a problem every app has and nobody wants to hand-roll. Its type-first design also means a model that gets the shape wrong fails loudly at build time.
