Invoset · WCAG 2.1 AA Scanner

Run a WCAG 2.1 AA accessibility scan on any open tab. Powered by axe-core; results stay on your device unless you save them.

Invoset Scanner runs a WCAG 2.1 AA accessibility audit on the page you are currently viewing and shows the result in a clean popup, in about five to ten seconds. It is built on axe-core, the open-source accessibility rule engine that Microsoft, Google, and Deque ship in their own products. The scan runs entirely on your device. Nothing about the page you scan is sent to a server, and no account is required. WHAT YOU GET - An overall score from 0 to 100 - Issue counts grouped by impact: critical, serious, moderate, minor - The top violations with the rule id, the WCAG success criterion, and a short description of what failed - A clear "nothing to flag" state when a page passes the automated checks HOW IT WORKS 1. Open any http or https page. 2. Click the Invoset icon in your toolbar. 3. Press "Scan this page". 4. Read the scored result in the popup. The scan only runs when you click. The extension never reads pages in the background and never tracks your browsing. WHAT IT IS NOT Automated testing catches a large share of accessibility problems, but not all of them. Issues like keyboard focus order, meaningful alt text, and reading flow still need human judgement. Treat the score as a fast signal, not a certificate, and pair it with manual review for anything legal or contractual. ABOUT INVOSET Invoset is a continuous WCAG monitoring service for small businesses in the United States. The website version re-scans your whole site every week or month, tracks changes over time, and produces an audit-trail report. This extension is the free, single-page version of that engine.
