Swagger Open Source Tools

Swagger was created by the team behind the original “Swagger Specification”, which has since been renamed to the OpenAPI Specification. Today, Swagger has evolved into one of the most widely used open source tool sets for developing APIs with rich support for the OpenAPI Specification, AsyncAPI specification, JSON Schema and more.
