About Swagger
Swagger is a suite of tools built around the OpenAPI and AsyncAPI specifications, covering API design, documentation, testing, and governance. It includes open source tools—Swagger Editor for designing APIs with real-time feedback and syntax auto-completion, Swagger UI for visualizing and interacting with API resources without implementation logic, and Swagger Codegen for generating client libraries and server stubs from OpenAPI Specification definitions.
Beyond the open source tools, Swagger offers a commercial product line (branded Swagger, formerly SwaggerHub, alongside Swagger Enterprise) that adds team collaboration features such as role-based access controls, API design standards and governance enforcement, a centralized catalog for visibility across APIs, functional and contract testing, and integrations with API gateways, version control systems, and webhooks.
The open source tools are positioned for individuals and small teams designing, building, and documenting APIs, while the commercial products target teams and organizations that need consistency, governance, and collaboration at scale across their API lifecycle. The company behind Swagger is SmartBear Software.
