Snowdog
Merchants who want the company that has published an actual screen-reader session on a Magento theme, who care that the tester was a real blind user rather than a scanner, and who will accept an agency with no published position on overlay widgets78 of 100Snowdog ranks first on a tie, and the tie-break is printed rather than hidden. It scores 78 and so does scandiweb; the rule declared in the methodology is that an equal total breaks on the criterion this page weighs heaviest, which is audit method at 24 points, and Snowdog takes 19 there against 16. It wins that criterion and the Magento criterion, and those two account for the whole of its advantage.
What earns the method marks is the rarest thing in this research: a published session, not a published promise. Its 2019 study of its own open-source Magento 2 Alpaca theme, on Magento 2.3, records a real test with a named blind tester using NVDA on Windows and TalkBack on Android, and it reports what broke in its own product. Snowdog writes that after the full page loaded the cursor jumps to the top of the page which is connected with Magento 2 content dynamically loaded with Ajax, that on the category and product page graphic presentation of product option, size and colors, called swatches in Magento 2, are hard to find because the container is not fully accessible, and that this caused a problem with Add to cart form validation. It also names unlabelled icon buttons on the product page, tooltips on checkout that are not fully accessible, a registration date picker that does not gain the focus so there is no option to choose the birth date, Recaptcha validation that does not always appear, and a mini cart that a screen-reader user cannot distinguish from the shopping cart page. It closes with a line most agencies would cut: although we weren't at 100% accessibility, our efforts so far had made some impact. Its service page states the method plainly, offering user testing with our professional testers, manual testing with assistive technologies, and automated tests.
It takes 20 of 20 on Magento specificity, the only full marks on that criterion anywhere on this page, and the second half of that comes from the theme layer. On its accessibility consulting page Snowdog states that our team was the key contributor to the major improvements in Hyva frontend theme, aimed at improving WCAG compliance, and it names Anna Karon as Accessibility Specialist and Senior Frontend Developer. Its named client is Biuro Paczka, on Adobe Commerce with Hyva and 10,000 SKUs, where it writes that an accessibility expert played a major role in improving the accessibility of the theme to make the store and its features compliant with WCAG, and that the primary focus was to ensure the entire purchase flow, from product browsing to checkout, was adjusted to be compatible with screen readers and other assistive technologies. It also claims that effort became incorporated into the Hyva theme 1.3.0.
Three things hold it to 78 and a buyer should weigh each. It states no conformance level for Biuro Paczka, only compliant with WCAG, which costs it 4 of the 16 available on client evidence and is the single reason scandiweb beats it there 13 to 9; the only published metric on that case is a 98% Google PageSpeed score, which is performance rather than accessibility. It publishes no mapping of findings to individual success criteria, holding it to 15 of 18 on the standard. And it publishes nothing whatsoever about overlay widgets, which costs it 4 points on the last criterion and is the reason scandiweb takes that one outright. On the credit side its own accessibility statement is real, targets WCAG 2.2 Level AA, sits in every page footer, and declares its own limitation: keyboard support, some media sections such as iframes and videos are inaccessible for keyboard-only users. On the Hyva authorship question this page takes no side. Snowdog claims the 1.3.0 contribution, Wagento credits the Hyva team for the same release, Aureate Labs credits Hyva, and Hyva's own guide is written by Snowdog's founder. Three parties describe one release and one claims authorship, so the page records who says what. Nothing in the score turns on it, because Snowdog's marks come from its own Alpaca diagnosis and its own service page.
