What Deque (axe Monitor / DevTools) does well
- Industry-standard detection engine
- Excellent developer tools
- Strong contributions to the W3C process
Where Deque (axe Monitor / DevTools) falls short
Every accessibility vendor has a target customer and a target solution. Deque (axe Monitor / DevTools)'s shape works for some teams and badly for others. The points below come up most often when buyers move off Deque (axe Monitor / DevTools) and what they wish they had asked sooner.
- axe Monitor is enterprise-priced
- No AI fix generation; you still write the patches yourself
Why teams pick Certvo instead
- Same axe-core detection engine, plus AI-generated code patches you can review and ship
- Lower cost to monitor across many sites — no per-seat enterprise pricing
- Public scan available free with no signup
Try a free public scan on the same URL you would test with Deque (axe Monitor / DevTools). Compare what each tool says is wrong and how each proposes to fix it.
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.
Frequently asked questions
Is Deque axe-core the same engine Certvo uses?
Certvo's automated detection layer is built on axe-core, the open-source library Deque maintains. This means the detection rules and WCAG mappings are the same foundation used by Deque's commercial products, browser extensions, and most other tools in the accessibility ecosystem. The difference is what happens after detection: Deque tools report issues; Certvo generates code fixes.
When would I use Deque axe DevTools instead of Certvo?
axe DevTools is ideal for developers doing component-level testing in the browser during active development — testing a modal before it ships, checking a new form layout. Certvo is a page-level and site-level crawler that monitors production deployments. The two are complementary: axe DevTools in development, Certvo in CI/CD and production monitoring.
What does axe Monitor (enterprise) add over the free axe extension?
axe Monitor is an enterprise platform that crawls entire sites, tracks issues over time, assigns ownership, and integrates with project management tools. It is priced for large organisations with dedicated accessibility teams. Certvo offers similar crawling and tracking at a fraction of the cost, plus AI fix generation that axe Monitor does not include.
