Our Verdict
OnlyEnable is the far more complete solution. Tenon.io charges $99/mo for an API that requires developer integration and catches only ~30% of issues. OnlyEnable starts at $29/mo and includes a visitor widget, manual expert audits, source-code fix recommendations, and a compliance audit trail — everything Tenon.io doesn't offer.

Where Tenon.io falls short
Honest drawbacks to know before you sign up.
API-only product — requires significant developer effort to build a useful workflow around it
Automated scanning only — catches ~30% of real WCAG issues; no manual expert review
No visitor-facing accessibility widget for end users
No source-code remediation guidance — just issue reports
No non-technical user interface — unusable without a developer building around it
No documented compliance trail or formal audit reports for legal defense
Limited customer support and community activity in recent years
In fairness — Tenon.io's strengths:
- Developer-focused accessibility testing API — easy to integrate into custom workflows
- Flexible API-first architecture allows integration with any tech stack
- Straightforward issue reporting aligned to WCAG success criteria
When Tenon.io might still make sense
Tenon.io is a reasonable choice for developer teams building custom accessibility testing pipelines who need a hosted API and are comfortable writing the surrounding tooling themselves.
For everyone else — which is the vast majority of businesses — OnlyEnable is the better choice.
Pricing — we cost less, include more
