SWR vs React Query: Choosing the Right Tool
Compare SWR and React Query across API surface, bundle size, and use case fit.
Bundle Size Comparison
SWR weighs approximately 7kb gzipped. React Query v5 is approximately 13kb gzipped. The size difference reflects React Query's additional features: query prefetching, query cancellation, a more detailed query lifecycle, and built-in DevTools.
For size-sensitive applications or simple fetch-display patterns, SWR's smaller footprint is a meaningful advantage.
SWR Strengths
SWR has a simpler, more minimalistic API. If your primary need is fetching data and displaying it with automatic revalidation, SWR covers this elegantly with very little boilerplate.
Being built by Vercel, SWR integrates exceptionally well with Next.js, especially for combining getServerSideProps or getStaticProps prefetch with client-side revalidation via fallback data.
