Founded in 2022, Fern is a startup focused on simplifying API integration by providing Stripe-level SDKs (client libraries) and documentation for REST APIs. The company's core mission is to enhance the developer experience by addressing common issues with APIs, such as being untyped, unstandardized, and out-of-sync. Inspired by internal tools from AWS and Palantir, Fern aims to enable every engineering team to offer easy-to-use and well-documented APIs. Their primary product transforms OpenAPI inputs into comprehensive SDKs and documentation.
Fern is backed by Y Combinator, a notable startup accelerator, which underscores its potential and credibility. Despite being a small team of fewer than ten people, Fern has made significant strides in the API development space. Their open-source approach has garnered attention and adoption within the developer community, contributing to more streamlined and efficient API integrations across various industries.
