New Swagger Editor and UI Now Support Designing and Documenting OpenAPI Specification 3.0 APIs

SmartBear Releases Updated Swagger Open Source Tools

SmartBear Software, the leader in software quality tools for teams, today announced the updated release of Swagger Editor and Swagger UI. This release adds support for the OpenAPI Specification (OAS) 3.0 and enables users to design and document OAS 3.0 APIs using the world’s most popular API tooling.

SmartBear is a founding member of the Open API Initiative (OAI) and donated the original Swagger Specification in 2015. As the next evolution of the Swagger Specification, last week the OAI released a new version known as the OpenAPI Specification 3.0. Major improvements to the new version of the specification include increased reusability, extended JSON Schema functionality and enhanced security definitions. With these updates, the OAS 3.0 has the power to better drive the full API lifecycle within organizations.

Recognizing the importance of the OAS 3.0, SmartBear released updates to the popular open source tools, Swagger Editor and Swagger UI. With the Swagger Editor and UI, speed and reliability are brought to the forefront of the API design and documentation process.

The Swagger Editor was one of the first dedicated API design tools allowing users to design and document RESTful APIs. With the latest release, users can use the Swagger Editor to describe OAS 3.0 APIs. The Swagger UI, the most widely used tool for visualizing OAS defined APIs, can now automatically generate documentation of an API defined in OAS 3.0. This enables API developers and consumers to visualize and interact with an API’s resources without having any implementation logic in place. The combination of the Swagger Editor and UI is downloaded once every three seconds.

“Empowering our users with the latest technology, such as the OAS 3.0, is of the upmost importance to us,” said Ron Ratovsky, Swagger Developer Evangelist at SmartBear. “As a founding member of the Open API Initiative, we’re proud to continue developing tooling to support the OpenAPI Specification.”

SmartBear is committed to supporting OAS 3.0 and will continue to develop and release updates to Swagger open source tools and SwaggerHub, the company’s integrated API design and documentation platform for teams.
