About This Tool

The Web Accessibility Tool analyzes a web page for accessibility conformance against WCAG 2.1 AA. It identifies automated violations, severity levels, and impact areas to help teams prioritize fixes. The analysis targets structural issues, color contrast, focus management, image alternatives, and semantic markup, returning a clear set of actionable tasks for developers.
Conceptually, the tool aggregates checks from a curated rule catalog aligned to WCAG criteria and computes a composite score. It produces a detailed issue list with rule IDs, locations, suggested remediation, and references. It supports configurable standards and can adapt to single-page applications or traditional multi-page sites.
Audience includes developers, QA engineers, accessibility consultants, content teams, and product managers who must demonstrate compliance, reduce risk, and communicate findings to stakeholders.
Unique value includes structured remediation guidance, exportable reports in JSON, CSV, or HTML, and integration-ready outputs that fit existing workflows. It emphasizes practical fixes, maintains a transparent scoring model, and enables rapid re-testing after fixes.

Frequently Asked Questions

Find Quick Answers

How is the accessibility score computed?

The score combines automated checks for contrast, keyboard navigation, ARIA usage, semantics, and image alt coverage. Each area contributes a weighted portion of the final score, with higher emphasis on critical WCAG criteria and practical remediations.

Can I test pages behind authentication?

If authentication is required, provide a test environment URL or a publicly accessible staging page. The tool cannot access protected resources, so the score reflects only reachable content and may miss issues in gated sections.

What export formats are supported?

Exports are available as JSON, CSV, or HTML reports. Each export includes the issue list, severity, locations, and recommended fixes to facilitate remediation tracking and stakeholder communication.

Does the tool handle dynamic or SPA content?

The tool can operate in a single-page app mode with extendable checks, but some dynamic accessibility issues require manual verification. It provides guidance and context for post-load content as part of the report.
