What's Good
MIT (vercel/swr), release v2.5.1 (2026-08-12). One hook handles caching, request deduplication, revalidation on focus and reconnect, pagination and mutation. Works with any transport (fetch, GraphQL, etc.). Maintained by Vercel and widely used with Next.js. ★~32.5k.
The Catch
Smaller than TanStack Query in features like devtools and fine cache control. With React Server Components, much fetching moves to the server, so you need SWR less in new Next.js apps.
Verdict
The light, simple choice for client-side fetching in React.
