A lightweight and convenient Chrome extension that provides a sidebar to quickly test your API endpoints without leaving your current tab. Send GET and POST requests, add custom headers, and view responses in multiple formats.
As a developer, you often need to quickly check an API endpoint or test a response. Switching between your browser, a code editor, and a dedicated API client like Postman can be cumbersome. This extension solves that by bringing a simple yet powerful API testing tool directly into your browser's sidebar. It's perfect for rapid testing, debugging, and development workflows.

- Select Method: Choose either GET or POST for your request.
- Enter URL: Paste the full API endpoint URL you want to test.
- Add Headers (optional):
- Click the + Add Header button to create a new header row.
- Enter the header name (e.g.,
x-rapidapi-key) and its value. - Add as many headers as you need.
- Add Body (for POST): If you selected POST, a body field will appear. Enter your JSON payload here.
- Send Request: Click the Send Request button.
- View Response: The response will appear at the bottom. You can switch between different views:
- Auto: Automatically detects if the response is JSON, an image, or plain text.
- Text: Shows the raw text body of the response.
- Image: Attempts to render the response as an image.
- Headers: Displays the status code and all response headers.
- Convenient Sidebar UI: No need to open a new tab or application.
- GET & POST Support: Covers the most common HTTP methods for testing.
- Custom Headers: Easily add any number of custom request headers, including authorization tokens.
