What are the limits of CSP Builder & Analyzer?
Local policy linting, not a bypass-proof CSP audit. Test report-only mode and application compatibility before enforcing. No automatic deployment. This tool processes inputs in browser memory and makes no upload or lookup request. Clear inputs or close the tab when finished. Exports and clipboard actions are explicit.
