Our verdict on ANDI
ANDI is a free, open-source web accessibility testing tool maintained by the Social Security Administration’s Accessible Solutions Branch. It runs as a browser bookmarklet on the page being reviewed, making it suited to developers and accessibility testers conducting manual web-content reviews, including Section 508-related testing. Its scope covers HTML, interactive elements, images, links, tables, page structure, color contrast, hidden content, and iframes.
The product’s main strength is the depth of its page-level inspection. ANDI can flag potential accessibility issues and expose accessible names and descriptions, screen-reader output, focusable elements, tab order, accesskeys, image alternative text, links, buttons, data-table cell associations, headings, lists, landmarks, ARIA roles, and language. It also combines automated and manual color-contrast testing with inspection of hidden content and iframes. That breadth gives reviewers several ways to examine how page semantics and interactive behavior may be presented to assistive technology.
ANDI is most appropriate when a reviewer needs a detailed view of one page and is comfortable working through a manual inspection workflow. Its bookmarklet format keeps the tool close to the page under review, but it is not a browser extension or a conventional site-wide scanning platform. Teams looking for recurring scans, API access, or CI/CD integration should choose a tool built around those workflows instead. For focused page analysis, especially around names, descriptions, focus order, structure, and screen-reader output, ANDI offers a broad set of free inspection aids.
