Fern is a developer experience platform that generates beautiful documentation websites, client SDKs, and a CLI from a single source of truth—your OpenAPI, GraphQL, AsyncAPI, or gRPC spec. It is built for the AI era, serving clean Markdown with auto-generated llms.txt and a built-in MCP server so AI agents and coding assistants can use your API out of the box. Key capabilities include docs-as-code publishing via GitHub, AI-powered search (Ask Fern), version and product switching, localization, and enterprise features like SSO, SCIM, and custom branding. Target users are developer relations teams, API platform engineers, and startups shipping production documentation and SDKs.
The complete picture — from everyday features to the technical detail builders and IT folks dig for.
