Third-Party Script Auditor

Categorize external scripts by purpose and measure their impact.

Run it on Apify All tools

Who it is for

Performance and security work that needs to know exactly what else is loading on the page.

What you would use it for

• List every external script, stylesheet and iframe, grouped by the domain serving it.
• Categorise third parties by purpose so the page-weight conversation has evidence behind it.
• Find tags nobody remembers adding — the usual outcome of a long-lived marketing site.
• Build the third-party inventory a CSP or a vendor review needs.

What you get back

One JSON record per page checked. These are the actual fields returned by the most recent successful run — read from the live catalogue, not a documented ideal.

Pricing

$1 per result. Pay-per-event through Apify — no subscription, and a run that returns nothing costs nothing.

Questions

Why does the third-party count matter?

Each external origin is a DNS lookup, a connection, a performance cost and a party that can execute code on your page. Most sites accumulate them and remove none. An inventory is the first step of both a performance budget and a Content-Security-Policy.
