Summary
Fern generates SDKs and API documentation from API specifications. Founded by Danny Sheridan, who previously worked at AWS, and Deep Singhvi, who worked at Palantir, they solve the problem of APIs being untyped and out-of-sync. They support TypeScript, Python, Go, Java, Ruby, C#, and PHP SDKs, and have been trusted by over 200 customers including Square, Webflow, ElevenLabs, Auth0, and Intercom since launching in 2023.
