One Swagger for VS Code 🚀
Universal 1-Tap API Documentation Explorer & Interactive Request Runner inside VS Code
One Swagger brings the full power of Swagger UI, OpenAPI exploration, and API testing directly into Visual Studio Code — with zero CORS restrictions, full $ref resolution, request history, and client code snippet generation.

openapi.json, swagger.yaml).

- Method-Tinted Accordions: Authentic Swagger UI styling (
GET Blue, POST Green, PUT Orange, DELETE Red, PATCH Teal).
- Dark Code Response Inspector: Live status badges, response latency, formatted dark JSON viewers, headers inspection, and 1-click copy/download.
- Universal Authentication: OAuth2 password flow, Bearer JWT, and API Key support with 1-click interactive lock icons on route headers.
- Request History: Local logging, search filter, date grouping, JSON export, and 1-click replay.
- Client Code Generator: Generate instant snippets for cURL, Fetch, Axios, Python
requests, and Go.
- Zero-CORS: Uses VS Code's Extension Host Node.js runtime to execute requests without browser CORS limitations.
