A developer platform for generating API documentation and SDKs from API definitions and structured developer inputs.
A developer platform for generating API documentation and SDKs from API definitions and structured developer inputs. It is most useful when the task matches its specific workflow, and generated code or recommendations should be tested before production use.
Fern helps API teams turn API definitions into documentation and client libraries. Its workflow is aimed at reducing the manual work involved in maintaining SDKs and developer-facing reference material across languages.
The platform is a strong fit for companies that publish APIs and want generated developer tooling to stay aligned with the source specification. AI features can assist parts of the workflow, but the central value is API tooling and generation. Teams should treat the API definition as the source of truth and test generated SDKs against real endpoints.
