Where Tanaguru is strong
Where Tanaguru is strong
- Open source and free to run, with an active automation focus.
- Large library of automated tests (~180) across RGAA, AccessiWeb, and WCAG.
- Scenario/scripted audits via Selenium for dynamic apps and flows.
- Fits CI pipelines for repeatable, automated regression checks.
Caveats to keep in mind
- Automation-first: automated tools detect only a fraction of WCAG issues, so expert manual review is still required.
- Self-hosting and setup carry technical overhead.
- Not a guided manual-audit workspace with evidence capture for non-developers.
- Reporting is engine-oriented rather than client-ready conformance reporting.

Frequently asked questions
- Is automated testing enough for compliance?
- No. Automated tools catch only part of accessibility issues. A conformance audit needs expert manual evaluation, which is exactly what CheckFox structures around assisted checks.
- Does CheckFox use automation too?
- Yes. CheckFox runs assisted checks, axe-core plus complementary rules built into CheckFox that go beyond it (a maintained, growing set), to surface obvious issues quickly, then guides you through the manual criteria that automation cannot judge.
- Do I need to host anything with CheckFox?
- No. CheckFox is a hosted SaaS. There is no engine to install, configure, or keep up to date.
