In their own words
Oobee
Oobee is a free automated accessibility testing tool powered by GovTech Singapore. It checks websites against WCAG 2.2 and can scan a page or an entire site from a URL. Reports identify issues by severity and affected elements, then suggest fixes that can include code-level improvements. Checks cover low-contrast text, unclear form labels, images without alternative text, unlabeled buttons or links, and missing language tags. Reports can be produced in HTML, PDF, or CSV. Teams can use the web interface, API, or desktop application for Windows and macOS, and scans can be integrated into CI/CD pipelines. GovTech describes Oobee as open source, and its listed Free scan plan costs nothing. The tool is intended for government officers, product owners, developers, designers, content managers, and accessibility consultants. Its homepage reports more than 790,000 pages scanned, more than 11.5 million accessibility issues discovered, and use by 99 government agencies. Its privacy statement says personal data is shared only with government agencies or authorized entities performing specific government services.
Pa11y
Pa11y is a free, open-source set of tools for checking website accessibility. Its command-line interface loads a page for a one-off test and highlights issues, while Pa11y CI checks a list of pages in continuous-integration workflows. Pa11y Dashboard tests pages daily and graphs improvements or regressions over time. Pa11y Webservice supplies JSON data for the Dashboard or a custom dashboard-style front end. The package runs from the command line or Node.js, uses HTML_CodeSniffer by default, and can also use the axe test runner. WCAG2AA is the default CLI standard, with WCAG2A and WCAG2AAA selectable. Reports can be human-readable CLI output, CSV, HTML, JSON, or TSV. Configuration uses command-line options or JSON and JavaScript files, and local HTML files can be tested with an absolute path. Pa11y provides API access, scheduled scans, site-level scanning, and CI/CD integration across Linux, macOS, Windows, web, API, and self-hosted setups. Pa11y 10 requires Node.js 22.13.0 or newer on an even-numbered release.
