Lighthouse vs VertaaUX

Compare Lighthouse performance-only audits with VertaaUX's UX-first approach that includes accessibility, clarity, and conversion analysis signals.

What Each Tool Covers

Lighthouse excels at performance metrics. VertaaUX adds UX, accessibility, and semantic issues tied directly to user outcomes.

When to Use Each

Use Lighthouse for performance diagnostics and VertaaUX when you need conversion-impacting UX fixes and shareable reports.

Suggested Workflow

Run Lighthouse in CI, then schedule VertaaUX audits for launch-ready UX and accessibility validation.

How to use Lighthouse and VertaaUX together

Combine performance and UX audits to cover the full quality surface of a marketing or product page.

  1. Run Lighthouse in CI on every PR

    Configure a Lighthouse budget for LCP, INP, and CLS. Block PRs that regress past the budget.

  2. Run a VertaaUX audit before merging to main

    Submit the staging URL. The audit returns UX, accessibility, and conversion findings that Lighthouse does not cover.

  3. Triage by category

    Performance issues belong with Lighthouse output; UX, accessibility, and conversion issues belong with VertaaUX output. Resolve both before release.

  4. Re-audit on production

    After deploy, re-run both tools on the production URL to confirm the staging-fix landed and CrUX field data, when available, agrees with the lab numbers.

Frequently asked questions

Does VertaaUX replace Lighthouse?
No. They cover different problems and work well together. Lighthouse is best-in-class for Core Web Vitals lab diagnostics. VertaaUX adds UX clarity, conversion friction, and a deeper accessibility analysis using axe-core plus its own analyzers.
Can I run both in CI?
Yes — that's the recommended setup. Run Lighthouse on every PR for performance regression detection, and run VertaaUX before merge to main for the broader UX and accessibility check. They surface non-overlapping issues.
How is VertaaUX's accessibility check different from Lighthouse's?
Lighthouse uses a subset of axe-core rules. VertaaUX runs axe-core in full plus AccessLint and custom analyzers (keyboard, live regions, semantic structure), and tags each finding with a fixability rating so you know what is mechanical vs needs human review.
Which is better for a shareable client report?
VertaaUX. Lighthouse reports are designed for engineers; VertaaUX produces a shareable URL with an executive summary, prioritized findings, and per-issue fix instructions that non-engineers can act on.
