What ARC Toolkit is

ARC Toolkit is a free, single-page browser tool for finding and addressing web accessibility problems on demand. It evaluates pages against WCAG 2.1 Level A and AA guidelines, with WCAG 2.2 coverage listed, and reports conformance failures or possible issues. Users can review findings by page element, choose which issues appear in reports, and scan again after making changes. The toolkit identifies color-contrast concerns and displays tab order as a visual path. It also supplies code-level remediation suggestions, lets users copy findings into bug-tracking software, and works with browser developer tools for developer and QA investigation. Additional checks can send a page URL or DOM to the W3C validator and run an ARIA checker. ARC Toolkit uses the rules engine shared with ARC Monitoring and the ARC API. Chrome and Firefox extensions are offered for macOS and Windows. There are no scheduled scans.
