Brew a Content Security Policy
-

Turn real page loads into a CSP you can ship.

+

Automatically generate a CSP for your site.

cspresso crawls up to N same‑origin pages with headless Chromium (Playwright), watches the assets that load, and emits a draft Content-Security-Policy header.

cspresso lets the browser do the hard part: execute the page, watch what it loads, and distill origins into directives.

+
+

+ It uses Playwright (a tool designed to run a browser in 'headless' mode, originally to help automate performing frontend testing of websites) to visit the website in the background and learn what directives of a Content-Security Policy would be needed in order to set such a header and still have the website function properly. +

+
+

+ It can also evaluate a provided CSP against a site and see if normal use of the site would trigger violations of the policy, before you ship it. +
