pa11y for scripts, Kuality for everything else
pa11y is the right tool when you need programmatic, deeply customized accessibility testing embedded in your build scripts. Kuality is the right tool when you want reliable, scheduled audits, trend dashboards, and CI/CD gates with no infrastructure to maintain. Many teams use both.
No infra to maintain
pa11y runs on your servers. Kuality runs on ours. No Node.js version conflicts, no Chromium binary issues, no CI runner configuration — just results.
Trend dashboards
pa11y gives you a pass/fail at the moment you run it. Kuality tracks WCAG scores across every scan so you can see regressions the moment they're introduced — not after users report them.
Proactive alerts
Kuality notifies you when accessibility scores drop. pa11y is silent unless you build notification logic yourself. Kuality integrates Slack, Discord, and email out of the box.
Free plan. No credit card. No Node.js setup.
