That was 21 checks. The engine runs 99, plus the AI vision lane.
The free check reads your markup. The on-prem engine renders your real flows and runs the full always-on catalog, and the AI vision lane critiques the screen the way a person would, on your hardware, behind your firewall. That's the paid part, and it ships behind the published proof.
