TanStack Query vs SWR vs plain fetch in 2026

data-fetching

Choosing a server-state library for a React app in 2026.

⏳ Consider

Confidence: 0.86

Decision Reason

TanStack Query for any non-trivial app; SWR if you want minimal API; plain `useEffect + fetch` for trivial cases only.

Best For

React apps that fetch data from a REST or GraphQL backend

Apps where all data is statically generated at build time (use Next.js RSC)

Apps with only one or two data-fetching screens (useEffect is fine)
