Rest API Inspector — Professional API Debugging Tool for Developers

===================================================================

Rest API Inspector is a powerful, lightweight Chrome extension built for frontend developers, full-stack engineers, QA testers, and anyone who needs to understand exactly what API calls their web application is making. Whether you are debugging a production issue, testing a new feature, auditing third-party integrations, or verifying that your app communicates correctly with a backend, Rest API Inspector gives you instant, clear visibility into every HTTP request — without ever leaving your browser tab.

Unlike the built-in Network tab in Chrome DevTools, Rest API Inspector is designed to be fast to open, easy to navigate, and focused purely on REST API traffic. It sits quietly in your toolbar, capturing requests in the background the moment you load a page. One click on any request reveals its complete profile: method, status, duration, all request and response headers, request body, and response body — with JSON automatically pretty-printed and syntax-highlighted.

Built on Chrome Manifest V3, the extension uses the absolute minimum permissions required — just tabs and activeTab. Everything is stored in memory only, never written to disk, and never sent anywhere.
