Overview

Product summary

Review the store description, core capabilities, and common use cases.

API Tester Pro is a professional and lightweight REST API testing extension built to help developers, testers, and students efficiently test, debug, and validate APIs directly from the browser.

This extension provides a focused and distraction-free environment to send HTTP requests, inspect responses, and troubleshoot API behavior without relying on external desktop tools. It is designed to support modern API development workflows while remaining fast, simple, and easy to use.

API Tester Pro supports common HTTP methods such as GET, POST, PUT, PATCH, and DELETE, allowing users to test endpoints with custom headers, request bodies, and authentication tokens. Responses are displayed clearly with status codes, headers, response body, and execution time, helping users quickly understand API behavior.

The extension includes built-in theme support, allowing users to switch between light and dark modes for better readability and comfort during long development sessions. Request history is automatically maintained so users can revisit, reuse, and debug previous API calls without rewriting them.

API Tester Pro is ideal for frontend developers testing backend integrations, backend developers validating endpoints, QA engineers verifying API responses, and students learning REST API concepts. It works entirely inside the browser, requires no login, and does not collect personal data.

By keeping the tool focused on a single purpose—REST API testing—API Tester Pro delivers a reliable and efficient experience that improves productivity and simplifies API debugging.
