One SDK. Any API.
Fully TypedTyped.
The type-safe API layer for TypeScript apps. Connect to REST, GraphQL, Firebase, WebSockets, SSE . All with one consistent interface and the best type safety in the ecosystem.
Works everywhere
One SDK that works with every framework, every API protocol, and every environment. Learn it once, use it everywhere.
One SDK. Any API.
Stop juggling libraries, hand-typing types, and rebuilding cache, retries, and offline in every project. HyperFetch is the complete data layer for every protocol you ship.
Schema → typed SDK
Point at any OpenAPI spec, get a fully typed client. No hand-written interfaces, no any.
Any protocol, one API
REST, GraphQL, Firebase, Sockets. Swap the adapter, keep the same createRequest / .send() everywhere.
Production data layer
Cache, queue, retry, dedup, offline replay. All built in. Stop re-implementing the same infra in every project.
End-to-end TypeScript
Params inferred from URL strings. Typed responses, payloads, query params, errors. Zero any.
React hooks built in
useFetch for queries. useSubmit for mutations. Loading, error, and data states all managed for you.
HyperFlow DevTools
Inspect every request, cache entry, queue, and event. Debug your data layer visually.
Runs everywhere
Browser, Node, edge, mobile, SSR. Same client, same behavior, every runtime.
Optimistic updates
Mutate the UI first, reconcile with the server. Smooth, race-condition-free.
Smart deduplication
Five components ask for the same data. One network call fires. Automatic.
