accessio-scan is a free, MIT-licensed command-line accessibility scanner for developers and engineering teams. Built with axe-core and Playwright, it scans a URL for WCAG violations and runs locally without an account or signup. The tool is designed for development and continuous integration workflows, with a page-focused approach that suits teams adding automated accessibility checks to their engineering process.

Its strongest fit is CI reporting. accessio-scan provides exit codes that can act as a CI gate, while console, JSON, and SARIF output support different reporting workflows. SARIF results can be integrated with GitHub Code Scanning, giving teams a direct path from an automated scan to code-scanning results. The scanner also waits for a CSS selector before scanning, which supports pages whose relevant content appears after initial loading. Developers who need code-level integration can use the programmatic Node.js scanning API.

The scope is intentionally narrow. accessio-scan currently scans a single page, so teams needing crawling or sitemap-based coverage should look for a broader platform. It also focuses on automated checks rather than manual accessibility review, and it does not provide scheduled monitoring. That makes it a practical choice for open-source, self-hosted scanning in development or CI, particularly when WCAG 2.1 or WCAG 2.2 coverage and SARIF output matter. Organizations seeking ongoing site-wide monitoring, manual assessment, or wider platform coverage should choose an alternative with those capabilities.
