SwaggerHub provides API design, testing, documentation, and governance tools for software teams. Swagger Studio combines a visual editor with a shared API catalog for collaborative design, including work by contributors who do not code. It supports OpenAPI and AsyncAPI specifications, style guides, templates, reusable components, and centralized governance. Teams can generate mock servers to test endpoints and use contract or functional tests that integrate with CI/CD pipelines. Swagger Portal creates API documentation and onboarding guides, with branded portals and access controls. Listed integrations include GitHub, GitLab, Azure DevOps, AWS, Bitbucket, Gradle, and ReadyAPI. The product is available on the web or self-hosted, and lists role-based access, SSO, version history, and custom domains. Swagger Enterprise is described as deployable on-premise or in the cloud and includes dedicated support and account management. A free plan covers basic API design and documentation. Listed Team plans begin at $740 a year for one user, billed over 12 months; pricing is also available on request.
