What Tenon.io does well
- Clean API surface
- Developer-friendly pricing
Where Tenon.io falls short
Every accessibility vendor has a target customer and a target solution. Tenon.io's shape works for some teams and badly for others. The points below come up most often when buyers move off Tenon.io and what they wish they had asked sooner.
- No fix generation
- No public-facing tools or VPAT generator
Why teams pick Certvo instead
- Public scan + API + AI fixes + free tools (contrast checker, statement generator, VPAT generator)
- No API wiring required for the core scan — accessible from the browser in seconds
- AI-generated patches, not just detection results
Try a free public scan on the same URL you would test with Tenon.io. 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
What is Tenon.io's main use case?
Tenon.io exposes a clean REST API that developers wire into their own dashboards, CI/CD pipelines, and project management tools. It is a data layer, not a full product — you build the reporting and workflow around it. This is ideal for teams that want complete control over how accessibility data is consumed and presented. Certvo provides the same scanning capability with a full UI, AI fixes, and free tools out of the box.
Does Tenon.io have a public-facing scan tool?
Tenon.io is primarily API-first — there is no consumer-grade scan interface comparable to Certvo's public scan. For developers evaluating the API, there is a basic test form. Certvo's public scan at certvo.com lets anyone scan a URL in 60 seconds without any API integration, making it faster for initial audits and demos.
