We audit accessibility across every page.
Magnolia Monitor runs a full accessibility audit on every page of your site every week — catching contrast failures, missing alt text, and more.
One page is a start.
Magnolia Monitor checks accessibility across your whole site, every week — not just the colors, but alt text, focus order, and everything Lighthouse flags.
