Webfree

OpenAPI Viewer is a self-hosted service for browsing and testing a REST API described with the OpenAPI 3.0 specification. It's configured through environment variables that control which documentation sources are allowed to load, and can optionally integrate with the SimpleDirectory identity service for shared theming. It's aimed at API developers and platform teams who want to host their own API documentation and testing tool rather than use a third-party service.
