Dock Accessibility Checker - a browser-based accessibility audit tool

Dock Accessibility Checker is a browser extension available for Google Chrome (opens in a new tab), Mozilla Firefox (opens in a new tab), Microsoft Edge (opens in a new tab), and Brave (opens in a new tab). It helps developers quickly identify digital accessibility issues on websites and web applications. The extension integrates directly with browser DevTools, allowing developers, QA testers, accessibility specialists, and auditors to analyze website accessibility without leaving their browser. Dock Accessibility Checker supports compliance efforts with WCAG 2.1 and WCAG 2.2, helping teams detect issues faster and generate professional accessibility audit reports.

Key Features

Automated WCAG Accessibility Audits

Scan an entire website or selected sections with a single click. Dock Accessibility Checker analyzes page code and highlights potential accessibility issues affecting users who rely on assistive technologies.

Export Audit Reports to DOCX

After completing an audit, you can generate a DOCX report containing detected issues, affected elements, and recommendations for remediation. This feature is particularly useful for development teams, agencies, public organizations, and companies conducting formal accessibility audits.

Website Structure Analysis

Review your document structure and quickly evaluate how content is organized. Analyze heading hierarchy, page regions, landmarks, and DOM structure from a single interface.

Focus Order Visualization

See exactly how keyboard users navigate through your website. Dock Accessibility Checker visualizes focus order using directional arrows, making it easy to identify incorrect tab sequences, skipped controls, and navigation issues.

Image and Alternative Text Analysis

Review all images on a page and verify the quality and completeness of alternative text descriptions.

Color Contrast Testing

Evaluate text readability and verify compliance with WCAG contrast requirements. The extension allows you to test contrast levels and preview changes without modifying your source code.

Highlight Elements Directly on the Page

Every detected issue can be instantly located within the page. Selected elements are highlighted visually, making remediation faster and more efficient.

Audit Individual Sections or Entire Pages

Not every accessibility review requires scanning an entire website. Dock Accessibility Checker allows you to audit individual components, selected sections, complete pages, or entire web applications.

Multilingual Interface

The extension is available in more than 20 languages. Error descriptions, recommendations, and interface elements can be displayed in the language most suitable for your team.
