About Fern
Fern is a platform that helps companies elevate their developer experience by automating the generation of SDKs and creating comprehensive API documentation. It allows users to start with an API specification (OpenAPI, AsyncAPI, OpenRPC, gRPC, or Fern Definition) and automatically generate client libraries in multiple languages, including TypeScript, Python, Go, Java, Ruby, C#, and PHP.
Beyond SDK generation, Fern also provides a robust documentation platform. It enables users to create SEO-optimized, versioned API documentation with features like API key injection, access control, and interactive API explorers. The platform supports docs-as-code workflows, allowing documentation to be versioned and released using Git, and offers customization options with JavaScript, CSS, and React components. Fern aims to save engineering time and improve the developer experience for API consumers.
