Dual-profile Core Web Vitals. Tells you which gate is lying - your CI, or your users.
Most perf audits run Lighthouse and call it done. We run Lighthouse and a separate real-world 2026 throttle profile, then surface the delta. When your lab score is 95 and your CrUX field data says 'poor', we tell you exactly what's hiding in the gap.
srcBoth profiles, every metric
Lab profile
Lighthouse on the same throttle CI uses. LCP, INP, CLS, FCP, TTFB, total page weight, render-blocking resources, image-format opportunities.
Real-world profile
2026 mobile throttle (slower CPU, slower network than Lighthouse defaults). Plus CrUX field data when available - your actual users' p75 LCP/INP/CLS from Chrome.
Delta analysis
Per-metric delta_* finding when lab and real-world diverge by 20%+. "Lighthouse is masking a real-world LCP regression - your CI gate is lying to you" - with a fix prompt for the specific bottleneck.
Lighthouse mismatch ruleId
A category-level finding when the gap is large enough to suggest your CI gate doesn't reflect user experience at all. The most consequential perf finding most teams have never seen.

Pro tier adds weekly cadence + regression alerts. The audit itself never costs anything.
