Swagger Editor for Quick API Testing

Found Swagger Editor useful for quickly visualizing and testing API specs.

What It Does

Swagger Editor converts OpenAPI YAML definitions into interactive API documentation.

Write your API spec on the left, see live preview on the right.

Online Version

No installation needed: https://editor.swagger.io

Quick Example

Paste an OpenAPI spec:

openapi: 3.0.0
info:
  title: My API
  version: 1.0.0
paths:
  /users:
    get:
      summary: List users
      responses:
        '200':
          description: Success

Instantly see:

• Interactive documentation
• Request/response examples
• Try-it-out functionality

Use Cases

Testing third-party APIs:

• Got an OpenAPI spec from a vendor? Load it in Swagger Editor
• See all endpoints and try them out

Designing new APIs:

• Write spec first
• See how it looks before implementing

Documentation:

• Generate API docs from your YAML

Local Setup

For offline use:

docker run -p 8080:8080 swaggerapi/swagger-editor

Quick way to work with OpenAPI specs without building custom tooling.
