Siteimprove is a full-suite enterprise platform that bundles accessibility with SEO, content quality, and analytics. If you just need accessibility scanning, you're paying for a lot of features you'll never use. Litmus gives you the same axe-core WCAG 2.1 AA scanning at a fraction of the cost, with no contracts, no sales calls, and results in minutes instead of weeks.
