About Fern
Fern is an open-source platform for generating software development kits (SDKs) and application programming interface (API) documentation. Developer-focused companies like Square, Webflow, Intercom, and more use Fern to streamline their development process, typically starting by uploading an API specification (OpenAPI, AsyncAPI, OpenRPC, and more). Fern supports SDK generation in popular programming languages, including TypeScript, Python, Go, Java, C#, PHP, and Ruby. The platform integrates seamlessly with tools like GitHub, Postman, NPM, PyPI, NuGet, and RubyGems. Fern is backed by Y Combinator.
