Fern

API documentation and SDK generation platform

About Fern

Fern is a platform that generates SDKs and documentation sites from API definitions. Day to day, companies use it to keep client libraries in several languages synced with their OpenAPI specs. For developers, the appeal is simple: less infrastructure busywork, faster feedback and tooling that fits into existing workflows instead of replacing them wholesale.
