Web Accessibility Checker
Run automated WCAG 2.2 accessibility checks on a public URL or local HTML and get actionable findings with element context and remediation.
Audit Input
Choose Public URL or HTML, set the viewport, WCAG level, and optional rule categories, then run the audit. Filter findings by severity, WCAG level or criterion, category, rule, or component, expand a finding for its selector, snippet, and remediation, and export JSON, Markdown, or CSV.
Manual Review
Automated checks (axe-core) cannot detect every accessibility issue and only cover the rendered state at audit time. Manual review with a keyboard and screen reader is still required. The report is not a certification or compliance claim and has no score.
Processing
HTML mode runs entirely in your browser inside an isolated sandbox and is never uploaded. Public URL mode sends the URL to CodingTool.dev; the server fetches the public page through a private-network guard and keeps nothing after responding. Only mode, viewport, level, categories, and filters are saved in this browser.
