A Standard Header, Not a Paid Feature
Content Security Policy follows an open, well-documented W3C specification — assembling the correct directive syntax is a matter of following that standard correctly, not something that should require a paywall. A free generator that helps you build a correct policy is all this genuinely requires.
What You Get for Free
- No account needed: select your directives, generate the header — nothing to register first.
- Built-in warnings: flags configuration choices that would weaken or defeat your policy's protection.
- Multiple directives covered: script-src, style-src, and others in one place.
- No usage limits on how many times you adjust your policy.
Who This Is For
Developers hardening a site against XSS, anyone responding to a security scan flagging a missing CSP, or a team standardizing policy across projects — a free generator covers this directly. If you're managing a strict, nonce-based CSP integrated with a server-side templating system, that requires actual code changes beyond any generator's scope — but for building a correct starting policy, this is exactly the right amount of tool.
