Pa11y

Check accessibility conformance.

Pa11y runs a WCAG conformance scan on the page during the Run. Use it when your team prefers Pa11y for page-level accessibility audits in the same journey as functional steps.

Pa11y Test Step

When to use it

• Scan a full page for WCAG violations after the screen is loaded.

• Set Conformance Level to the WCAG level your team expects. The default is AA.

• Pair with Accessibility when you also want a Lighthouse score threshold.

• Add Check computed role and Check computed label on key controls.

For a Flow Builder walkthrough, see Add accessibility checks.
