GitHub Accessibility Scanner
What it is
GitHub Accessibility Scanner is a free, MIT-licensed GitHub Action for finding accessibility barriers in websites, repositories and dynamic content. It scans against WCAG 2.2, using Axe by default and supporting AccessLint and plugins as additional engines. Findings can become GitHub issues, with tracking across runs to prevent duplicates and close issues when a finding disappears. Copilot is optional: the scanner can file issues without it, while Copilot can be assigned issues to suggest changes and create pull requests. Settings include scan URLs, authentication, screenshots, issue grouping, experimental and best-practice findings, and per-URL selectors. It works with public and private repositories and supports GitHub Enterprise Cloud. Setup requires GitHub Actions and Issues to be enabled, available Actions minutes, and a fine-grained personal access token with write permissions. The scanner is in public preview, with ongoing feature development; suggested fixes are not guaranteed to be fully accessible. It does not scan mobile apps, desktop applications, documents, email templates or PDFs.
