A Lighthouse Accessibility Alternative — When a Score Isn't Enough
Lighthouse gives you a quick accessibility score tucked in beside performance and SEO. Loupe is dedicated to accessibility: it runs the full axe-core ruleset as a one-click overlay, explains every issue in plain English, and exports a client-ready report. Free, in Chrome & Edge.
Full axe-core ruleset · a fix-list, not a score · runs locally
Lighthouse is the audit tool built into Chrome DevTools, and it's genuinely useful — it gives you a fast read on performance, SEO, best-practices and accessibility in one run. But when accessibility is the thing you actually care about, that convenience becomes the limitation: accessibility is one tab among several, and what you get is a number from 0 to 100 rather than a list of things to fix. If you're looking for a Lighthouse accessibility alternative, it's usually because you've hit exactly that wall.
A score isn't a fix-list
Lighthouse's accessibility audits are powered by a subset of Deque's axe-core rules, then rolled up into a single score. That score is handy as a pulse check, but Google itself is clear about the catch: a perfect 100 does not mean your page is accessible. It only reflects the automated checks Lighthouse runs — not the full ruleset, and not the many things only a human can judge. So a high number can quietly give you false confidence, while the real issues that get sites complaints and lawsuits sit just outside what the score measured.
Where Loupe is different
Dedicated to accessibility, and built to help you fix things rather than grade them:
- The full axe-core ruleset, not a subsetLoupe runs the complete axe-core rules, so it surfaces issues a Lighthouse score may never include.
- A list of issues, not a numberEvery problem is spelled out individually — what it is, where it is, and how to fix it — instead of being averaged into a score.
- Plain-English explanationsEach issue reads in normal language with its exact WCAG criterion, so you can forward findings to clients and teammates.
- White-label client reportsExport a branded PDF — Lighthouse is a single-page developer audit, not a client deliverable. Pro
- Full-site crawl in one reportScan many pages into one combined report instead of auditing a single URL at a time. Pro
- One click, on any pageNo opening DevTools, no waiting through a performance run — click the toolbar icon and accessibility issues appear in context.
Loupe vs Lighthouse, side by side
| Loupe | Lighthouse | |
|---|---|---|
| Focus | Accessibility only | One of performance / SEO / a11y / best-practices |
| Detection engine | Full axe-core ruleset | Subset of axe-core |
| What you get | An issue list + how to fix each | A 0–100 score |
| Explanations | Plain English + WCAG criterion | Technical audit notes |
| White-label client PDF | Yes (Pro) | No — developer audit |
| Full-site crawl | Yes (Pro) | Single page per run |
| CI / performance & SEO too | Accessibility-focused | Yes — its strength |
| Free tier | Yes — scanning is free | Yes |
| Paid price | $19/mo or $190/yr | Free |
Lighthouse is excellent for a fast all-round health check and CI gating; the comparison above is about accessibility depth specifically.
Which should you actually use?
They're complementary. Reach for Lighthouse when you want a quick all-round score — performance, SEO and a rough accessibility pulse — or to gate a build in CI. Reach for Loupe when accessibility is the job: you want the full ruleset, an actual list of issues with plain-English fixes, and a branded report to hand a client at the end.
A common workflow is to use both — Lighthouse for the quick number during development, Loupe to work through and document the real accessibility issues before you ship or deliver. And the honest rule applies to either: automated tools are a strong first pass, not full WCAG conformance on their own.
Past the score, into the fixes
Add Loupe, open any page, and click once. The full ruleset, every issue in plain English with the fix — and a client-ready report when you need one.
Add Loupe to Chrome — freeFree forever for scanning. Pro ($19/mo or $190/yr) adds full-site crawl, AI explanations, saved projects, and white-label PDF reports.
FAQ
Is a 100 Lighthouse accessibility score good enough?
No. Google states plainly that a perfect Lighthouse accessibility score doesn't mean your page is accessible — it only reflects a subset of automated checks. A high score is a good sign, not a guarantee. To actually fix things you need the full list and how to resolve each, which is what Loupe provides.
Does Loupe use the same checks as Lighthouse?
They share lineage — Lighthouse's accessibility audits use a subset of axe-core. Loupe runs the full axe-core ruleset, so it can surface issues Lighthouse's subset doesn't, and presents them as an actionable list rather than a score.
Is Loupe better than Lighthouse for accessibility?
For accessibility specifically, Loupe is more focused: the full ruleset, plain-English fixes with WCAG criteria, and a client report. Lighthouse stays great for a fast all-round health check and CI gating.
Can I get a client report?
Yes. Loupe Pro exports white-label PDF reports with your branding and can crawl multiple pages into one — something Lighthouse's single-page developer audit doesn't do.
