REST APIs underpin the internet but are still painful to work with. They are often untyped, unstandardized, and out-of-sync across multiple sources of truth.

Deliver Stripe-level SDKs and Docs to your API users. Upload your OpenAPI, or define your API in Fern's simpler format, and generate SDKs in popular programming languages. Fern handles publishing to package managers like NPM and PyPI. When you use Fern for SDKs and Docs, you get SDK code samples automatically populated in your documentation.
