Silent Recon is a Chrome extension for passive browser-native security reconnaissance during web testing. It helps surface CORS issues, missing security headers, API endpoints, JavaScript intelligence, auth/session indicators, sensitive JSON patterns, and workflow chains while you browse. Findings stay local in the browser, with approved-target mode, target locking, dashboard views, and export controls for focused triage.














Hey Product Hunt!
I built Silent Recon to make browser-side web security reconnaissance faster and more focused during web testing.
Instead of running a manual scan first, you can browse a target normally and let the extension passively surface useful signals: missing security headers, CORS issues, API endpoints, JavaScript assets, auth/session indicators, sensitive JSON patterns, and workflow-shaped routes.
This is still early. The jump from 0.3 to 1.0 is the first serious version jump, not the final shape of the product. The foundation is now in place: paid access, richer dashboard views, saved context, and a clearer workflow. With real users putting it through practical scenarios, giving feedback, and supporting continued development, Silent Recon has room to grow into a must-have tool for security professionals.
A few important notes:
- It is passive and does not attack, fuzz, exploit, or modify traffic.
- Findings are processed and stored locally in the browser.
- You can limit capture to approved targets or lock it to the current target.
- The free version gives a local preview, while Pro unlocks deeper dashboard views, retention, workflow chains, and exports.
- Pro monthly and annual plans both include a 7-day free trial.
For the Product Hunt community, I also created a launch discount:
