About CSP Header Generator
Content Security Policy helps reduce cross-site scripting and injection risk by telling browsers which sources are allowed for scripts, styles, images, frames, fonts, and network requests. A good CSP can limit damage if a page accidentally includes unsafe content.
This generator creates a starter CSP header that you can adapt for your application. It is useful for security reviews, static sites, SaaS dashboards, documentation sites, and apps that want stricter browser protections. CSP is powerful, but overly strict policies can break analytics, fonts, embeds, or inline scripts.
Start in report-only mode when possible, review violations, then enforce the policy once expected sources are covered. Pair CSP with other headers such as HSTS, Referrer-Policy, and X-Content-Type-Options.
