About this tool

Made for the task at hand.

Make long policies readable and spot several high-value configuration warnings. The checks are advisory, not a complete security audit.

How to use

  1. Paste one Content-Security-Policy header value.
  2. Review each directive and its ordered source list.
  3. Investigate warnings before changing the deployed policy.

Common questions
Does this validate every CSP keyword?

No. It performs structural parsing and selected safety checks rather than full browser-grade validation.

Will the policy be enforced?

No. Parsing does not apply the policy or load any listed source.
