Swagger Editor
Design and document REST APIs with the OpenAPI specification.
Overview
Swagger Editor is a browser-based editor for writing API definitions in the OpenAPI Specification (YAML or JSON). As you type, it validates your definition and shows a live, interactive preview of the documentation.
Defining the API first lets frontend and backend teams agree on the contract early, and the same file can be used to generate client code, server stubs and documentation.
Where it is used
- Designing a new REST API
- Documenting an existing API
- Sharing an API contract with partners
- Teaching REST concepts
