Wacelio: web accessibility auditing against WCAG 2.2
Wacelio: web accessibility auditing against WCAG 2.2
Spanish-language service to audit the accessibility of websites and online shops against WCAG 2.2, prioritise issues and fix them at the source, with no overlays.
LaravelAccessibilityIn-house product
Web accessibility fixed at the source
Since 28 June 2025, Spain’s Law 11/2023 has required much of the consumer-facing online retail sector to be accessible, and many solutions simply add a widget on top of the site. Wacelio, conceived and built by AGQ, finds the barriers, explains how to fix them and helps document the work, without touching the client’s website.
Approach
A real browser visits each site on desktop and mobile with axe-core and custom keyboard, focus and 320 px layout tests, while a checklist guides the manual review.
Outcome
Reports that separate confirmed failures from what a person must review, with fix instructions for each issue.
Technology
A stack built to analyse real websites
Laravel handles accounts, scans, reports and alerts, MySQL stores each site’s history and Playwright drives the real browser that runs axe-core and the custom tests.

Frequently asked questions about Wacelio
The essentials about the product and how it was built.
Wacelio is a Spanish-language service that audits the accessibility of websites and online shops against WCAG 2.2: it detects issues, explains how to fix them and guides the manual review.
No. Automated tests only detect some of the problems. Wacelio helps find, fix and document them, but human review and the legal decision rest with each business and its adviser.
No. It only visits the site to analyse it and adds no code. It is not an overlay either: the website’s team makes the fixes by following each issue’s guide.
Yes, on verified sites and with a test account. It never makes payments or confirms orders, and the payment gateway is reviewed manually.
Laravel and MySQL on the server, Playwright to drive a real browser, and axe-core alongside custom tests for the analysis.
