WCAG Accessibility Checker — Loupe

Free WCAG accessibility checker. Finds contrast, alt-text, ARIA and label issues on any page — and explains how to fix each.

Loupe is a free accessibility checker for Chrome. Click the icon on any page and it runs an instant WCAG scan — powered by axe-core, the same engine behind most professional accessibility tools — then shows every issue directly on the page and tells you how to fix it. Most checkers hand you a list of failures. Loupe explains each one in plain English, points at the element it came from, and drafts the fix. WHAT IT FINDS • Colour contrast that fails WCAG AA — a full contrast checker built in • Missing or empty alt text on images • Form fields with no label • Broken, misused or orphaned ARIA • Heading and landmark structure problems • Keyboard and focus issues • Links and buttons with no accessible name Every issue is mapped to its exact WCAG 2.1 / 2.2 success criterion. HOW IT WORKS • Click the toolbar icon — the scan takes about a second • Issues appear grouped by severity, right on top of the real page • Click any issue to jump straight to the element that caused it • Read the plain-English explanation of what is wrong and why it matters • Optionally get an AI-drafted code fix, which you review before shipping • Turn any scan into a shareable web report or a branded PDF FOR FREELANCERS AND AGENCIES Scan a client's site, then hand them a report with your own logo on it instead of a screenshot of someone else's tool. The free tier is the entire checker — Pro is for when you need to deliver something. FREE, FOREVER Unlimited scans · WCAG 2.1 and 2.2 AA testing · in-page highlighting · plain-English explanations · the WCAG criterion behind every issue · no account, no signup PRO — $19/month or $190/year White-label PDF reports carrying your own logo · full-site crawl that rolls many pages into one report · saved client projects PRIVACY The scan runs entirely inside your browser. Loupe does not collect your browsing history and never uploads the pages you scan. The optional AI fix sends only the single failing element's HTML, and nothing is stored. WHY IT MATTERS NOW The European Accessibility Act is in force, and ADA web-accessibility lawsuits in the US keep climbing year on year. Catching WCAG issues while you are still building costs a fraction of fixing them after a complaint lands. AN HONEST NOTE Automated testing catches a large share of accessibility problems — not all of them. Loupe is a strong first pass and a genuine time-saver, but it is not a substitute for manual testing with a keyboard and a screen reader, and it is not a compliance certificate. Any tool promising one-click compliance is overpromising. Built on axe-core. Works on Chrome and Edge. Privacy policy: https://getloupe.dev/privacy
