Command-line accessibility testing that runs in CI pipelines.
Why we recommend it
Automated testing catches perhaps a third of accessibility issues — but running it on every commit means that third never regresses, which manual audits alone can't guarantee.
Strengths
- Runs in CI, catching regressions before release
- Tests against WCAG 2.1 rulesets
- Dashboard available for tracking over time
Keep in mind
- Automated tools catch only ~30% of real accessibility issues
- Still requires manual testing with actual assistive technology
- Command-line setup assumes developer comfort
