  • lighthouse-ci

    Automate running Lighthouse for every commit, viewing the changes, and preventing regressions

    • lighthouse-ci - If you're looking to run a comprehensive set of tests in your CI environment, lighthouse-ci brings all the power of Google's Lighthouse app to the table. In addition to accessibility checks, lighthouse-ci will report on your app's performance, SEO and best practices in one of the most polished standalone reports available.

  • DomainAccessibilityAudit

    Web application to create domain and subdomain accessibility audits, with violation statistics.

    • DomainAccessibilityAudit - I found this tool while researching ways to test an entire website for a11y issues and this was a perfect fit. You can feed it a root URL to start testing on and it will scrape all links on all subsequent pages and perform an audit, essentially crawling the entire site and producing a report of a11y issues. You can also input a sitemap.xml if you want to test a specific set of pages instead of crawling the entire site.
