What Fern does
Fern provides tooling for generating software development kits (SDKs) and API documentation directly from your API definitions. This positions it as a resource for engineering teams aiming to streamline integration experiences for external developers. The product is operated by BuildWithFern.com.
Tools in this space help automate the process of turning an API specification into consistent, up-to-date client libraries and accompanying documentation across multiple languages. Fern is likely aimed at making APIs more accessible by reducing friction for developers looking to adopt and use them. It fits into the broader API developer tools market, alongside other SDK and documentation generators.
