What AChecker is
AChecker is a web-based accessibility checker with WCAG 2.1 coverage. It performs automated scans and supports mobile testing through the service. The free plan uses a freemium model. Named options include AChecker Basic for reports covering a domain, Lighthouse Single for a Lighthouse scan on either mobile or desktop, and Lighthouse Full for Lighthouse scans on both mobile and desktop. AChecker focuses on automated checking and reporting rather than guided repair. The listed capabilities do not include manual review tools or remediation guidance. There is also no browser extension and no CI/CD integration. This makes the service suited to people who need browser-based automated accessibility checks, mobile coverage, and domain or Lighthouse reports.
Who it suits
