SwaggerHub

SwaggerHub is a cloud-based platform by SmartBear that centralizes the design, documentation, and governance of APIs built with the OpenAPI Specification. It supports a design-first workflow, allowing teams to create and edit OpenAPI definitions in YAML or JSON, with real-time validation, autocomplete, and linting within a shared editor. API definitions can be versioned, forked, and managed through lifecycle stages, and published to private teams or publicly discoverable catalogs.

Core features include a centralized API repository, collaboration with roles and permissions, and a built-in, interactive documentation experience powered by Swagger UI. It also offers mock servers for prototyping, code generation support for multiple languages, and automated linting to enforce API style and consistency. The platform emphasizes discoverability and reuse by enabling catalogs of APIs and clear governance over changes and approvals.

SwaggerHub supports automation and integration with development workflows through REST APIs and a command-line interface, as well as connections to version control systems such as GitHub, GitLab, and Bitbucket. This enables teams to synchronize OpenAPI definitions with their repositories, enforce review processes, and integrate API design into continuous integration and delivery pipelines. The platform is used by organizations pursuing design- and contract-first strategies for API programs.
