OpenAPI is an extensible language. And over the past few days, I've been exploring new ways to make those language extensions more discoverable and easier to use.
KaiZen OpenAPI Editor is an Eclipse-based editor for the OpenAPI Specification (OAS). OpenAPI v2, formerly known as the Swagger specification, is the most widely used and supported API description language, and OpenAPI v3 is a new major version, released in July 2017 with significant new features and improvements.
KaiZen OpenAPI Editor supports both OpenAPI v2 and v3, and it's available now on the Eclipse Marketplace.
