AC3 Frontend Auditor

AC3 Frontend Auditor is Jeff Brigman's experimental WordPress plugin for collecting frontend performance and page-structure evidence. Administrator audit sessions capture browser resources, DOM measurements, mutations, layout shifts, long tasks, and selected runtime information. Optional providers add summarized Query Monitor data or Google PageSpeed Insights Lighthouse results.

The alpha supports sitemap-backed browsing sessions, including FluentCommunity routes, and stores results for later history review and export. It uses short-lived signed audit sessions rather than acting as an unrestricted public monitoring service. Available measurements depend on the provider and on whether the page was captured with a version that records them.
