Honest comparisons

How Certvo compares to other accessibility tools

The accessibility-tooling market is split between two camps: overlay vendors who add a script to your site, and audit platforms that report issues. Certvo is in a third camp — AI audit plus code patches you can review and ship. Each comparison below is written without marketing spin: what the other tool does well, where it struggles, and when you should still pick it over us.
