### What we like

Parses OpenAPI or AsyncAPI formats to auto-generate SDKs (JS, Python, Go, .NET, Java, Ruby) and docs. Use Fern’s own definition format for more control (can be exported to OpenAPI). Can auto-publish to npm, PyPI, NuGet and Maven Central. Generates a changelog. Integrates with pull request reviews.

### Tradeoffs

Support for PHP, Swift, Rust & Terraform not available yet.
