Certvo vs axe-core: which actually makes you compliant?

What axe-core does well

• Free, auditable, and the de-facto industry reference implementation

• Runs anywhere: Jest, Playwright, Cypress, Chrome extension, CI pipeline

• Very low false-positive rate — findings are defensible in an audit

• No vendor lock-in; the rules are public

Where axe-core falls short

Every accessibility vendor has a target customer and a target solution. axe-core's shape works for some teams and badly for others. The points below come up most often when buyers move off axe-core and what they wish they had asked sooner.

• It reports violations; it does not tell you what the corrected markup should be

• No crawling — you point it at one page at a time and wire up the rest yourself

• No history, no regression tracking, no report you can hand to a buyer

• No mapping from a violation to the EAA, ADA or Section 508 obligation it affects

Why teams pick Certvo instead

• Runs the same axe-core rules, so findings match what your own CI would report

• Adds the missing half: generated fixes written against your actual element and styles

• Crawls the site, keeps scan history, and flags regressions between releases

• Produces the accessibility statement and VPAT that procurement asks for

When you should still pick the other tool

Bluntly: if the only thing you need is a visible widget on your site (e.g. as part of a settlement consent decree that names a specific overlay product), an overlay vendor is the path of least resistance. Certvo does not ship a widget. We give you patches; the widget is only a UI for the audit.

If you have an enterprise procurement process that already has a long-running contract with a competitor and the buying motion would take six months to switch, you can use Certvo alongside as the audit-and-fix tool while the widget keeps sitting on the page.
