TypeScript-first schema validation
Declare data schemas once and get static types plus runtime validation: the standard validation layer of the TS ecosystem.
The TypeScript-first schema validator: define once, get static types + runtime validation + inference. The ecosystem's lingua franca for API boundaries (tRPC, TanStack, FastAPI-style ergonomics in TS).
Who it's for
TypeScript developers who want the de facto schema validation library with static type inference.
