Aceit Toolbar

Accessibility testing toolbar. Highlight the HTML structure of a page and quickly find potential accessibility issues.

Aceit Toolbar is a browser extension built to make accessibility work in web interfaces easier. The tool gives you a clear overview of the page's structure and helps you spot issues such as broken heading hierarchies, missing landmarks, or unusual paragraph markup. With one click you can highlight: - Landmarks (header, nav, main, aside, footer, regions) and content that sits outside any landmark - Heading structure, with warnings when a level is skipped - Lists (ul, ol, dl) and their items - Tables, captions, headers and header relationships, with warnings for tables missing header cells - Paragraphs, empty paragraphs and double line breaks - Images, including SVGs, and their text descriptions. Designed with security at the core: - Manifest V3, no build step, no bundlers - the files in the package are the files that run - No runtime dependencies - Only the activeTab and scripting permissions - no host access, no background data - No network requests, no telemetry, no storage - Works identically in Chrome, Edge, Vivaldi and Firefox 109+ Available in English, Swedish, Norwegian, German, French and Spanish. Aceit Toolbar is developed by Useit Consulting as a free, open tool for teams doing hands-on accessibility work.
