About Swagger
Swagger is a set of API tools built around the OpenAPI Specification. It helps teams design, document and test APIs from one shared definition.
What it does
Swagger lets you write an API description in OpenAPI, AsyncAPI or JSON Schema, then produce documentation, client code and server stubs from it. The Swagger Editor checks your definition as you type. Swagger UI turns the same file into interactive docs that people can try in a browser.
Key features
- Edit OpenAPI definitions with live feedback
- Browse and try endpoints in generated docs
- Generate client libraries and server stubs
- Enforce shared API design standards
- Run functional and contract tests
Who it's for
Backend engineers, API designers and documentation writers who want one source of truth for an API. Larger organizations may also use the commercial platform for governance and team work.
Pricing and good to know
Several core tools are open source, and Swagger also sells an enterprise product with team features. The site offers a trial of its hosted platform. Check the vendor's current plans before buying an enterprise license.
