API Documentation & Design Tools for Teams - Enable quality APIs for humans, LLMs, agents, and innovation
About Swagger
Swagger is a comprehensive API development platform that enables teams to design, build, test, and document APIs with confidence. It provides both open-source tools and enterprise solutions for the complete API lifecycle. The platform places OpenAPI and AsyncAPI specifications at its core, offering streamlined workflows for API design, documentation, testing, and governance across organizations of all sizes.
As part of SmartBear Software, Swagger has become the industry standard for API documentation and design. The platform combines free open-source tools like Swagger Editor, UI, and Codegen with enterprise-grade features in SwaggerHub for team collaboration, API governance, and standardization at scale.
