Fern
Docs, SDKs, and CLIs for your API from one source of truth
Fern is a developer platform that generates API documentation, SDKs in multiple languages, and a CLI from a single OpenAPI (or GraphQL/gRPC/AsyncAPI) specification. It supports modern API protocols and is designed for enterprise use with features like SSO, RBAC, self-hosting, and localization. Teams use Fern to keep their developer experience tooling in sync and up to date automatically.
Fern takes an OpenAPI (or other API spec) as a single source of truth and automatically generates documentation websites, idiomatic client SDKs, and a CLI.
