Gud API
A lightweight, full-featured API client built into your editor. Test REST and GraphQL APIs, organize requests into collections, manage environments, and generate code snippets — without switching to Postman or another external tool.
Available on OpenVSX and the VS Code Marketplace. Learn more at gudlab.org/gudapi.

Request History
- Every request is auto-saved to history (last 100 entries)
- View history in the sidebar with method, URL, status, and timestamp
- Click any entry to reload it into the request builder
- Persists across VS Code sessions
Cookie Management
- Cookies from responses are automatically captured and stored
- Cookies are auto-sent on subsequent requests to matching domains
- Cookie Manager to view, enable/disable, and delete cookies by domain
- In-memory storage — cookies reset when VS Code restarts
Collections
- Save and organize requests into collections and folders
- Click to load any saved request back into the builder
- Right-click to rename, delete, or create new folders
- Supports deeply nested folder structures
Import
- Postman v2.x collections (including nested folders, headers, body, and collection variables)
- Thunder Client collections
- OpenAPI 3.x / Swagger 2.0 specs (paths become requests, tags become folders)
- Import via sidebar button or command palette
Environments & Variables
{{variable}} syntax in URLs, headers, and body — resolved automatically on send- Collection-level variables imported from Postman (e.g.
{{base_url}})
- User-defined environments with key-value editor and enable/disable toggles
- Environment selector in the toolbar — switch between environments instantly
- Variable resolution order: environment overrides collection variables
Editor Integration
- Activity bar icon for quick access
- Matches your VS Code theme automatically (light, dark, high contrast)
- Works without a workspace open (stores in VS Code global storage)
- Keyboard shortcut: Enter to send request
Getting Started
- Install the extension from OpenVSX or the VS Code Marketplace
- Click the Gud API icon in the activity bar
- Enter a URL and press Send
- Click Save to add the request to a collection
To import an existing collection, click Import in the sidebar and select a Postman, Thunder Client, or OpenAPI JSON file.
