APIVoid Request Tester for Chrome and Firefox

APIVoid Request Tester is a browser extension designed for Chrome and Firefox that enables developers to send HTTP requests to API endpoints and inspect the responses directly from within the browser. It addresses the need for quick, day-to-day API testing without requiring a standalone API client, offering a lightweight and accessible solution for developers who want to test and debug APIs efficiently.

The extension provides a complete HTTP client interface, supporting all common HTTP methods including GET, POST, PUT, DELETE, PATCH, HEAD, and OPTIONS. Users have full control over custom headers and the request body, with the ability to choose from raw JSON, x-www-form-urlencoded data, plain text, or no body at all. Content-Type headers are set automatically based on the selected body format, but can also be manually overridden. One of the central features is the ability to save any request as a named profile, which can be re-run with a single click at any time. These profiles can be edited, deleted, imported, or exported as JSON files, allowing for easy sharing and backup across different browsers or machines.

APIVoid Request Tester offers detailed response inspection, breaking down each response into status code, total response time, and payload size, with the body and headers available for closer examination. JSON responses are automatically pretty-printed and syntax-highlighted for readability, and all response headers are displayed in a table for quick access to information such as Content-Type and CORS headers. Users can copy or save response bodies and headers for further analysis. The extension does not enforce CORS restrictions, as requests are sent from the extension itself, making it possible to test API endpoints that would normally reject browser-based requests.

All saved profiles are stored locally within the browser's extension storage, and no data is uploaded to external servers. The extension does not collect analytics, telemetry, or tracking data, ensuring privacy and security for users. APIVoid Request Tester fits within the class of HTTP client tools, specifically tailored as an in-browser solution for API testing and debugging tasks.
