openapi-ts

openapi-ts is a code generation tool that converts OpenAPI specifications into TypeScript, producing production-grade SDKs, Zod schemas, TanStack Query hooks, and supporting over 20 plugins. It is designed for developers building type-safe API clients, particularly those using frameworks like React Query or Zod, and is trusted by companies like Vercel and PayPal. Its interest lies in automating the creation of fully typed, maintainable API layers, reducing boilerplate and runtime errors while integrating seamlessly with modern TypeScript ecosystems.
