AccessLint vs AllyShield

AccessLint checks accessibility during development, on pull requests, and on live sites. Its WCAG 2.2 engine has 95 rules and a stated 53ms median audit across 5,000 real-world sites. Pull-request reviews inspect changed files and leave inline comments with the relevant rule and a suggested correction, but do not fail builds or block merges. Deploy-triggered scans require Starter or Pro, run asynchronously, and also do not synchronously fail builds. Saved user journeys can run daily, with email alerts for new violations or changes against a baseline. The toolkit provides checks for Playwright, Vitest, and Storybook, while pull-request reviews use a GitHub App. Starter and Pro include shareable read-only evidence reports with before-and-after screenshots of affected elements. Free covers public-repository pull-request reviews, one daily monitored flow, and violation trends. Starter costs $19 a month or $190 a year; Pro costs $349 a month or $3,490 a year. AccessLint says automated checks alone cannot make a site compliant.

AllyShield is a web-based service for automated accessibility scans against WCAG 2.2. It supports mobile testing, CI/CD integration, and remediation guidance, with plans ranging from a free allowance to higher-volume options. The Free plan costs nothing, billed monthly, and allows 3 scans per month, 1 page per scan, and 1 domain. Starter costs €49/mo and includes 25 scans per month, 5 pages per scan, 3 domains, and 5 AI fixes per scan. Pro costs €99/mo and raises the limits to 100 scans per month, 25 pages per scan, and 10 domains; it also includes scheduled scans and API access. Agency costs €149/mo, with 500 scans per month, 50 pages per scan, 50 domains, white-label reports, and custom rules. Enterprise costs €799/mo, with unlimited scans, 100 pages per scan, unlimited domains, SSO/SAML, and dedicated support. AllyShield does not offer manual review tools or a browser extension.
