csp-header-generator

To generate a safe Content-Security-Policy, this tool synthesizes live specs and tested configurations to produce a deployable policy. It handles external resources, inline scripts, and dynamic content without modifying application code.

Strict-dynamic with per-request nonce rotation allows trusted scripts to load without explicit allowlists. The generator provides guidance on implementing this approach across SSR frameworks, discussing tradeoffs compared to hash-based methods.

The best way to roll out a Content-Security-Policy is a staged approach from report-only to enforcement. This tool provides a rollout plan with verification passes to ensure your policy works correctly before full enforcement.

Yes, this CSP generator handles complementary security headers including Permissions-Policy, Referrer-Policy, COOP, COEP, CORP, X-Content-Type-Options, and HSTS. It cites authoritative sources for every directive entry.

Automated CSP generation is honest about limitations where precise static detection of dynamic content and inline scripts is difficult. It provides read-only guidance and configuration plans rather than automatically deploying policies to your application.
