Aceit Toolbar от Useit Consulting

Aceit Toolbar is a lightweight accessibility inspection extension built for enterprise environments where every installed tool must pass a security review.

Click the icon and choose a mode to visually highlight:
- Landmarks (header, nav, main, aside, footer, regions) and content that sits outside any landmark
- Heading structure, with warnings for skipped levels
- 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 and SVGs, with alt text inspection and missing-alt warnings

Designed for security review:
- Manifest V3, no bundler, no build step - the files in the package are the files that run
- Zero 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 Aceit / Useit as a free, open tool for teams doing hands-on accessibility work.
