Monitor, block, and proxy HTTP requests made by websites and extensions. The ultimate tool for developers, QA testers, and privacy advocates. ReadOnly Monitor gives you a clear X-ray view of what data is leaving your browser. While standard ad-blockers stop ads, ReadOnly Monitor focuses on state-changing network requests—POST, PUT, DELETE—that send your data to servers. Whether you are debugging an API, auditing a suspicious website, or ensuring no data leaks from your browser, this extension puts you in control. 🚀 Key Features 🔍 Real-Time Request Monitoring Instantly see how many GET, POST, PUT, and DELETE requests are being made by the active tab. Visual Dashboard: Clean, modern popup interface displaying live request counts. Detailed Logs: View the exact URL and HTTP method of every write request. Extension Monitoring: Detect background requests made by other installed extensions to ensure they aren't silently sending data. 🛡️ ReadOnly Mode (Write Blocking) Turn your browser into a "read-only" device for specific sites. Block Outbound Data: Automatically block all POST, PUT, and DELETE requests. Prevent Accidental Actions: Browse critical tools without fear of modifying data (e.g., deleting a database record). Security Auditing: Test how web applications behave when write APIs fail. 🌐 Advanced Proxy Routing Route specific traffic through your own proxies without changing system-wide settings. Granular Control: Route traffic only for specific domains (e.g., *.test-env.com or api.internal). Protocol Support: Supports HTTP, HTTPS, and SOCKS proxies. Easy Configuration: Setup and switch proxies instantly from the popup. 🖥️ Versatile Interface Options Popup View: Quick stats at a glance. Side Panel: Keep a persistent log of network activity open while you browse. Pinned Overlay: A floating "Always-on-Top" widget inside the webpage to monitor traffic in real-time without leaving your workflow. 💡 Use Cases For Developers: Debug API calls without opening the full DevTools network tab. Verify that your frontend is calling the correct endpoints. For Security Analysts: Audit websites for hidden data collection and analyze traffic patterns. For Privacy Users: Ensure no unauthorized data is being sent by sites or extensions. Whitelist trusted domains and block the rest. For QA Testers: Verify "ReadOnly" user roles or test application error handling by artificially blocking write requests. 🛠️ How to Use Install & Click: Click the extension icon to see a summary of network requests for the current tab. Monitor Logs: Open the popup to see a list of recent improper write requests (POST/PUT/DELETE). Activate ReadOnly Mode: Toggle the switch to block all write requests for the current session. Pin Overlay: Click "Pin to Page" to keep a mini-monitor visible while you interact with the page. Configure Proxy: Use the "Proxy Routing" settings to send specific traffic through a custom proxy server (HTTP/SOCKS). ✨ Free vs Pro Free Version: Monitor GET, POST, PUT, DELETE request counts. View logs of recent write requests. Manage Domain Whitelist to exclude trusted sites.
