Script Sentinel - CSP Generator

Generate an editable Content Security Policy candidate for the active tab with Script Sentinel.

Generate a Content Security Policy (CSP) candidate for the website you’re viewing—without manually inventorying every resource. Script Sentinel scans the active tab’s public URL only when requested. It observes scripts, styles, fonts, images, frames, and network destinations across 1 to 3 reached pages, then returns a copyable CSP candidate with a security score, coverage details, and review warnings. KEY FEATURES Scan between 1 and 3 pages Merge related subdomains to simplify policies Detect mixed content and review external domains Include SHA-256 hashes when supported by observed evidence Copy the CSP alone or with optional security hardening headers Review page counts, scores, warnings, and partial-scan notices Keep up to five recent results locally Use light or dark mode with clear scan-progress feedback Open a public website, select the extension, choose your options, and click Generate CSP. Keep the popup open while the scan completes. No account is required. NEED DEEPER SCANNING?
