Fern helps you elevate your developer experience with two powerful products:
-
SDKs - Automatically generates production-ready SDKs that respect the idioms of each language. We support TypeScript, Python, Go, Java, Ruby, C#, PHP, and Swift, with Rust coming soon.
-
Docs - Creates interactive API documentation that developers actually want to use. Features include AI-powered search and chat, content migration tools, docs-as-code workflows, API key injection, access control (RBAC), and versioning.
Both products work with OpenAPI, AsyncAPI, OpenRPC, gRPC, or our simpler Fern Definition format, and can be deployed in the cloud or self-hosted for enterprise security and compliance requirements.
