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.
APIs are the neural connections of the digital economy, allowing systems to connect, collaborate, and converse with meaningful data. But these connections don't start with fully working APIs; they start with API design.
RepreZen API Studio started with the goal of enabling deep interoperability, by unifying data representations across APIs. The core of the product was the API modeling language that became RAPID-ML. API Studio provides the tooling: the RAPID-ML editor, live documentation and diagram views, sandbox testing and code gen framework.
