openapi-typescript

Radar: Initial MIT

Generates TypeScript types directly from an OpenAPI description — types only, no client runtime and no generated transport code.

Where it applies

Jobs this tool actually does, and the surface each one is exercised on.

Get compile-time safety against an API contract without adopting a generated SDK.
coding-agent

Often the right choice for an agent over a full SDK generator — one file, no runtime dependency, and the diff is reviewable.

Detect a breaking provider change as a type error in CI rather than at runtime.
