Next-Generation Swagger Editor Supports AsyncAPI Specification for Event-Driven APIs

SmartBear offers widest range of free, open source API design, documentation, and editing capabilities with ability to interact with multiple API types in a single experience
Somerville, MA — September 08, 2022 —

SmartBear, a leading provider of software development and visibility tools, has released the next generation of Swagger Editor, the most widely used  open source API editing tool on the market, now with support for the AsyncAPI Specification. Used for designing, defining, and documenting RESTful APIs in the OpenAPI Specification, the new Swagger Editor adds rich support for teams and individuals working across Event-Driven APIs using the AsyncAPI Specification.  

“As the API landscape rapidly evolves, supporting a broad spectrum of API specifications and languages is at the core of our mission at SmartBear,” said Frank Kilcommins, API Technical Evangelist at SmartBear. “We have rebuilt the popular Swagger Editor to offer native editing and rendering within multiple web browsers across multiple API specifications and language formats. Further, extensibility is at the foundation of SmartBear tooling, so we continue to ensure ease of extension, as we enable quick adoption of new specifications and future versions in continued support of the open source API community.” 

Leveraging Monaco Editor, the new Swagger Editor is greatly enhanced with rich editing features of a modern integrated development environment (IDE), including language specific documentation, better auto-completion, validation, syntax highlighting, go to reference, and find symbols.  

Swagger Editor continues its integration into SwaggerHub, the company’s API development platform and choice of API designers, developers, and architects who are scaling their approach to building, testing, and deploying high quality APIs that business stakeholders and consumers demand. 

Join SmartBear, along with open source developers, technologists, and other leaders who are furthering open source innovation, at the Linux Foundation’s Open Source Summit, taking place on September 13-16, 2022 in Dublin, Ireland.
