Axeazy vs Google Lighthouse for Accessibility

Opening answer

Google Lighthouse gives you a free, fast accessibility score for one page in Chrome, and that score is useful for spotting clear faults. Axeazy gives you code fixes for those faults, weekly rechecks across a site, and a dated record of the work. Lighthouse answers the question, what does this page score right now. Axeazy answers the next question, what changed in the code, who reviewed it, and what will be checked again next week. Keep Lighthouse for quick checks, and add a fix workflow when a score alone no longer moves the work forward.

How a Lighthouse score is built

Lighthouse runs inside Chrome DevTools, and its accessibility category uses axe-core rules. Chrome docs explain the scoring in plain terms on Lighthouse accessibility scoring. The score is a weighted average of all accessibility audits. Weighting is based on axe user impact assessments. Each accessibility audit is pass or fail. A page gets no partial credit on an audit, so one failing element can fail that audit outright. Chrome docs give a clear example: if some buttons on a page have accessible names, but others do not, the page gets 0 for the buttons audit.

That pass or fail rule explains why a score can drop sharply after a small change, and why a score can rise sharply after fixing one repeated fault. It also explains why a score is not a share of faults. A page with 9 passing audits out of 10 does not necessarily score 90, because audits carry different weights, with heavier audits having a bigger effect. Manual audits and low-impact and best-practice audits are not included in the score table in Chrome docs, because they do not affect the score. That means a Lighthouse score leaves manual checks outside the number, even though those checks matter for real use.

Use the score as a trend signal on the same page, under the same conditions, not as a verdict on a whole site. Run it on the homepage, then on a key inner page, then on a checkout or form page, and keep the three results separate. A single homepage score says nothing about a form buried three clicks deep, and a single score after a redesign says nothing about whether the fix for a contrast fault was reviewed and kept.

What Lighthouse leaves for you to do

After a Lighthouse run, you hold a list of failed audits, each tied to elements on that one page. Someone still has to edit the code, test the change with a keyboard, check contrast with new color pairs, and run Lighthouse again. For a developer working in Chrome all day, that loop is fast and familiar. For a business owner with no developer time, that loop is where work stalls. The audit list grows, the score moves a little, and the same faults return when new content is published.

Lighthouse also checks one page at a time in its usual DevTools use. You can run it again on another page, and you can automate runs, but the basic unit is still a page, not a site with a schedule and a dated history by default. That is fine for a page level check. It is not a substitute for a monitor that watches new pages each week and keeps a record of findings and fixes in date order.

Contrast is a good example of the gap between a score and a fix. Lighthouse flags background and foreground colors with an insufficient contrast ratio, with a weight of 7 in Chrome docs. That flag tells you a pair fails. It does not pick a new pair, apply it, or ask for approval before a visible color change goes live. Use the contrast quiz to practice judging text against its background, then decide on a new pair with a human review step, rather than letting a tool change visible colors on its own.

What Axeazy does with the same faults

Axeazy starts from axe-core checks as well, with 98 automated checks against WCAG 2.0, 2.1 and 2.2 AA plus best practices. It then fixes code in 14 categories: alt text, skip navigation, language attributes, form labels, link names, button names, ARIA labels on custom widgets, ARIA attribute validity, keyboard tab order, pinch to zoom restrictions, iframe titles, table header structure, landmark structure and heading structure. Those categories line up closely with the faults Lighthouse flags, such as missing button names, missing form labels, missing alt attributes and invalid ARIA attributes, so a Lighthouse list can become an Axeazy fix list without redefining the work.

For a site with a GitHub repo, fixes arrive as a real pull request with a visible diff for the owner or developer to review and merge. For WordPress, a free plugin applies 3 instant render time fixes: a skip navigation link, a page language attribute and an alt text fallback, with no account needed. Paid plans monitor weekly and give dated reports, so a new fault on a new page is found on the next weekly scan. Axeazy also publishes its risk score method on Axeazy methodology, where the score is described as a heuristic risk indicator, version 2026.05, based on axe-core impact ratings, and explicitly not a WCAG score or a legal assessment. That honesty about what a score is, and what it is not, is the same habit to bring to a Lighthouse score: use it as a signal, not as a verdict.

Quick comparison

• Price to start: Lighthouse is free inside Chrome DevTools. Axeazy free scan is $0, homepage only, 60 seconds, no signup and no card.
• Unit checked: Lighthouse checks one page per run. Axeazy paid plans cover a site by site count and page caps, with weekly monitoring.
• Result given: Lighthouse gives a weighted score from 0 to 100 plus failed audits. Axeazy gives scan findings plus code level fixes and dated reports on paid plans.
• Fix step: Lighthouse leaves edits to the site owner or developer. Axeazy delivers code level fixes, with pull request review for GitHub repo sites.
• Score meaning: Lighthouse weights audits by axe user impact, with no partial credit. Axeazy methodology weights rules by axe-core impact and severity, and states the result is a heuristic indicator, not a legal assessment.
• Record over time: Lighthouse results are per run, unless you save and track them yourself. Axeazy paid plans give timestamped scan history and dated PDF reports.

How to choose

First, decide how you will use a score. If you want a quick check before a release, and a developer is ready to fix the failed audits the same day, Lighthouse alone is enough for that page. If you want a score that stays useful across a site and across months, pair Lighthouse with a scheduled scan and a fix record, so the number is backed by dated findings and dated fixes.

Second, test the same page in both tools. Run Lighthouse on your homepage, note the failed audits, then run the free scan and compare the findings. Look for agreement on button names, form labels, alt attributes and ARIA validity, and look for differences in grouping. Agreement builds trust in the fault list. Differences in grouping often decide which report your team will act on first.

Third, read the wider checker guide at website accessibility checker pricing, free to paid to see how free page checks, paid sitewide scans and fix workflows price by different units. That wider view helps when a free score looks cheap but the fix time behind it is not, and when a paid plan looks dear but the reviewed fixes behind it save developer hours.

Axeazy in this comparison

Axeazy fits a reader who likes the Lighthouse check but needs the fixes applied and rechecked each week. Start with the free scan on Axeazy homepage, which takes about 60 seconds. Then compare plans, remembering that paid prices are shown at checkout and annual billing saves 20 to 25 percent. The capabilities page lists Starter at $29 a month, Pro at $79 a month and Agency at $199 a month as listed figures, so confirm the checkout total before you pay. For WordPress, start with the free plugin for the 3 instant render time fixes, then weigh paid plans for weekly scans, alt text saved to the media library and auto captioning.

FAQ

Is a Lighthouse score of 100 proof that a page works for everyone?

No. A score of 100 means the scored audits passed on that page at that time. Manual checks, meaning, reading order and real keyboard and screen reader use still need human review. WCAG 2.2 sets the criteria behind those audits, and ADA guidance on web accessibility notes that a clean automated report does not necessarily mean everything is accessible. This is general information, not legal advice. If you received a demand letter or were sued, talk to a qualified attorney.

Why did my Lighthouse score fall after one small change?

Because each audit is pass or fail with no partial credit, and audits carry different weights. One new button without an accessible name can fail the button name audit outright, even if every other button passes. Fix that one pattern, rerun the check, and the score should recover if no other audit failed in the meantime.

Should I replace Lighthouse with Axeazy?

No, keep Lighthouse for quick page checks in Chrome. Add Axeazy when you need code fixes, weekly monitoring across a site and a dated record. The two tools share axe-core roots, so they should agree on many clear faults, and that agreement makes the fix list easier to trust.

Which pages should I check first?

Check the homepage, the most visited landing page, and the most important form or checkout page. Those three pages cover first impression, main entry and main task. After those three, work through inner pages by traffic and by task importance, not by alphabetical order.
