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. With one click you get a clear overview of a page's structure and quickly spot issues that affect screen-reader users, keyboard users and people relying on text spacing. The toolbar bundles inspection modes for the structural HTML aspects that matter most for accessibility — such as landmarks, headings, lists, tables, forms, images, links and buttons, accessible names and keyboard tab order — plus utilities for applying the WCAG 1.4.12 text-spacing minima and disabling CSS to verify content holds up without styling. Every mode marks the relevant elements directly on the page with clear colours and labels, and warns about common issues such as skipped heading levels, missing alt text, links without an accessible name, or tables without header cells. A floating in-page navigation bar steps through every finding in order with screen-reader announcements for each one. 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, Opera 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.
