Legend-State is a fast, signal-based state management library for React and React Native with fine-grained reactivity and minimal boilerplate. It also includes a powerful sync and persistence system enabling local-first apps with optimistic updates and backend plugins like Supabase and TanStack Query.

Use cases

• manage global state in React without boilerplate
• minimize React re-renders with fine-grained reactivity
• build local-first apps with offline persistence and sync
• sync app state with Supabase or a custom backend
• replace Redux or Zustand with a faster observable-based store
• persist state locally in browser or React Native apps

When to choose

• you want the fastest possible React state library with minimal renders
• you need local-first sync with optimistic updates and retries
• you want an all-in-one state, caching, and persistence solution
• you prefer observable/signal-based reactivity over reducers and dispatchers

When to avoid

• you need state management outside the React/React Native ecosystem
• your team relies on Redux-style devtools and middleware patterns
• you only need simple server-state fetching without local persistence
