Third-party scripts and cookies review

External scripts and cookies affect performance, privacy, and security. This tool lists third-party script hosts, embeds, and response cookies so you can review vendors before a privacy audit or Core Web Vitals push.

What to look for

Unexpected ad networks, abandoned chat widgets, duplicate analytics hosts, and cookies set without a clear purpose. Prefer loading non-essential vendors after consent and deferring anything not needed for first paint.

Useful next steps

  • Map each host to a business owner
  • Drop unused SaaS embeds from templates
  • Align cookie banners with what actually loads
  • Pair with the performance audit after cleanup

Frequently asked questions

Is this a full privacy compliance audit?

No. It is a discovery aid for scripts and cookies on a public URL.

Why do results differ from DevTools?

Server HTML and fully rendered sessions can differ when scripts inject assets client-side.
