Deploying is solved; deploy quality is not. We score five AI app builders on the SEO, accessibility, and performance of the app they actually ship. v0 leads at 9/10.
We audited the deployed output of seven AI app builders with Lighthouse, axe-core and a structured SEO checklist - auditing the production build, not the in-editor preview. Performance was the strongest dimension across the board; accessibility was the weakest, with colour-contrast and form-label failures common. Lovable and v0 led overall, but no builder shipped a clean accessibility pass out of the box. This page reports per-dimension scores and the specific failures that recur, so you know what to fix after export.
