Testkase Accessibility Toolkit

Auto-detect accessibility issues in web pages using WCAG standards

TestKase Accessibility Toolkit is a free, one-click accessibility scanner that lives right inside your Chrome DevTools. Find and fix WCAG violations on any web page in seconds — no setup, no CI pipeline, no waiting for the next audit cycle. WHY INSTALL IT • Catch accessibility issues before your users do — or before your compliance team does. • Actionable results, not a wall of rule codes: every issue comes with a clear description, the exact HTML element, a unique CSS selector, severity level, and a suggested fix. • Works on any site — staging, localhost, production, or a competitor's page you're benchmarking. • Designed for speed: run a full WCAG 2.2 AA scan in under a second on most pages. WHAT IT DOES • Runs accessibility audits against the full WCAG family (2.0, 2.1, 2.2 — Levels A, AA, and AAA) powered by the industry-standard axe-core engine. • Groups issues by severity: Critical, Serious, Moderate, Minor — so you know what to fix first. • Highlights failing elements directly on the page and lets you inspect them in DevTools with one click. • Includes a Workflow Analyzer that quietly watches the page as you click through a user journey (login, checkout, form submit) and flags any new accessibility issues introduced by dynamic content. • Lets you sign in with your TestKase account to save scan reports, share them with your team, and track accessibility debt over time. • Supports custom scan configurations: pick which WCAG version to test against, include/exclude best-practice rules, and toggle experimental checks. WHO IT'S FOR • QA engineers adding accessibility checks to existing manual test flows. • Front-end developers catching issues while coding, before PRs are opened. • Accessibility consultants and designers producing evidence-rich reports for clients. • Product teams preparing for audits (ADA, Section 508, EN 301 549, European Accessibility Act). PRIVACY All accessibility rules run locally on your machine — no page content is sent anywhere. The only network request is the optional, opt-in sign-in to your TestKase account for saving reports. You can uninstall or sign out at any time. Built by the TestKase team (testkase.com) — a modern quality-assurance platform used by QA teams worldwide.
