Overview
Monitor, log, and share API network activity for QA testing workflows.
API Catcher: The Ultimate Network Monitor for QA & Developers Monitor, log, and share API network activity with ease. API Catcher is a Manifest V3 extension designed to streamline debugging and testing workflows by capturing every XHR and Fetch request in real-time. Key Features: * Automatic Network Interception: Captures all outgoing requests with full details including method, URL, headers, body, and response. * Side Panel Support: Open the monitor in your browser's native sidebar for persistent, side-by-side tracking as you browse. It automatically follows your active tab as you switch between sites. * DevTools Integration: A dedicated "API Catcher" tab inside Chrome DevTools for deep-dive analysis and wide-screen viewing. * Initiator Context: See exactly which page triggered a request. Every log entry identifies the source page URL and title. * Export & Share: Copy any request as a ready-to-use cURL command (including origin comments), formatted JSON, or create a secret GitHub Gist with one click. * Fully Responsive: A clean, dark-themed UI that scales perfectly from a narrow sidebar to a full-browser dashboard. * Secure PAT Storage: Your GitHub Personal Access Token is stored safely using Chrome's encrypted local storage for secure Gist sharing. Why use API Catcher? Traditional network tabs can be overwhelming and lose data on refresh. API Catcher provides a focused, searchable, and persistent log of your API calls. Whether you are validating request payloads, debugging headers, or sharing reproduction steps with your team via Gist, API Catcher makes the process seamless and efficient. How to use: 1. Click the extension icon to open the Side Panel monitor. 2. Browse any website to see API calls stream in automatically. 3. Click a request to view detailed headers and pretty-printed JSON bodies. 4. Use the filter bar to quickly find specific calls by URL, Method, or Status code. Built for modern QA workflows. No data ever leaves your browser except when you choose to create a Gist.
