D2i AccessScan
A powerful, privacy-first WCAG 2.1/2.2 accessibility auditor for Chrome. Instantly detect violations on any page or crawl an entire website — no external API calls, no data transmission, no account required.
Two Powerful Scan Modes
Single Page Scan
Instantly audit the currently open page using axe-core, the industry-standard accessibility engine. Results appear in seconds with a full severity breakdown — Critical, Serious, Moderate, and Minor — plus code-level remediation guidance.
Full Website Scan
A built-in BFS (breadth-first search) crawler discovers and scans pages across your entire website automatically — with a configurable page limit from 5 pages all the way to unlimited. Each page is opened, audited, and closed — giving you a complete site-wide accessibility picture with zero manual effort.
