Shared
swr only
React apps needing shared state without prop drilling, derived/computed state that updates automatically, fine-grained re-render control, per-route or per-feature isolated state.
Read-heavy React apps: dashboards, profiles, lists. When you want simple cache-first data with background refresh. When components far apart need to share server data without prop drilling.
Non-React environments (Jotai is React-only). Complex state machines (use XState). Apps already committed to Redux with large middleware ecosystems.
Complex mutation workflows with optimistic updates and rollbacks (react-query/TanStack Query is more powerful for this). Server-side rendering where you need full control over data fetching timing.
