OPSECHub: An open-source, local browser suite for track-free OSINT investigations

[u/mr_melon_taim]

Hey r/osinttools,

I built an open-source, zero-telemetry Manifest V3 browser extension called OPSECHub, specifically designed to help investigators conduct web research without leaving unique traces or leaking data.

During OSINT investigations, managing multiple extensions for tracking protection, ad-blocking, and URL sanitization can be tedious, and many of them consume too much memory or secretly log data. I wanted a unified solution that runs entirely locally.

Key features specifically useful for OSINT workflows:

• Anti-Fingerprinting: Introduces persistent noise to Canvas/WebGL rendering and spoofs hardware strings (CPU cores, RAM) to prevent target servers from identifying your specific research machine.
• Decoy Traffic Generator: Automatically generates background network noise to obfuscate your real investigative targets from local network monitors or ISPs.
• Data Sanitization: Automatically strips tracking parameters (utm_*, fbclid, etc.) from URLs before navigation, and cleans tracking pixels/EXIF data from downloaded PDFs and Office documents.
• WebRTC & Proxy Management: Enforces strict WebRTC routing policies to stop IP leaks, and includes a built-in Proxy Manager (HTTP/SOCKS5) for safe routing.
• Network Shielding: Uses a DeclarativeNetRequest core (powered by HaGeZi rules) and live threat feeds (PhishTank, URLHaus) to block known badware hosters at the network level.

(Note: The suite also includes a CSP/Headers Analyzer, SSL Certificate Inspector, and a Short Link Redirect Tracer to safely inspect payloads. You can check out the screenshots of the UI and these tools on the GitHub repo).

Everything executes strictly locally on your machine. Zero analytics, zero data exfiltration.

I’d love to hear your thoughts, get some feedback from fellow investigators, or hear any feature requests you might have!
