Lighthouse is the gold-standard performance audit — built into Chrome DevTools. Nexus runs on the same engine but adds the layer Lighthouse intentionally doesn't: dollar impact per finding, ADA risk classification, AI search visibility, and a prioritised fix plan.

FAQ: NEXUS VS LIGHTHOUSE

What's the difference between Nexus and Lighthouse?

Lighthouse is the gold-standard performance audit — built into Chrome DevTools. Nexus runs on the same engine but adds the layer Lighthouse intentionally doesn't: dollar impact per finding, ADA risk classification, AI search visibility, and a prioritised fix plan.

Is Nexus a free alternative to Lighthouse?

Yes — Nexus runs a full 5-pillar website audit (Performance, SEO, Accessibility, Security, AI Visibility) free, with no signup required. Recurring monitoring is available on paid plans starting at $19/month.

Does Nexus check accessibility (ADA / WCAG) like Lighthouse?

Nexus runs a full WCAG 2.1 AA scan as one of its 5 pillars and flags the specific failures most commonly cited in ADA litigation. Most competing tools either don't include accessibility or treat it as a generic checkbox.
