Fern specializes in creating type-safe, idiomatic SDKs in various programming languages from API definitions. Their platform interprets OpenAPI or a simplified Fern format to produce robust client libraries and automatic documentation for APIs. The code generation process is streamlined: import API definitions, select code generators, and publish packages to their respective registrars like npm or pypi. Fern provides end-to-end type safety, retry logic, and the ability to enrich SDKs with custom code. Their documentation is auto-updating, maintaining brand consistency and integrating easily into CI/CD workflows. Their services accelerate and improve the API development process, enhancing developer experience.
