Common questions
Which is better, Lovable or B12?
We don’t rank builders. We show what the sites people publish with them have in common: where they’re published, what they’re built with and what people make, from 890 real examples. Which suits a project depends on the project.
How can I tell if a website was made with Lovable or B12?
Enter its address in the AI Website Detector: it names the builder whose traces it finds, with the line it found them in. Code edited by hand or moved off the builder can leave none, so “none found” never proves a site wasn’t made with Lovable or B12.
Where do these numbers come from?
From our scans, as of 29 Oct 2026: each site’s newest full result whose traces name the builder with high confidence, leaving out sites with phishing evidence, adult, gambling, finance and personal sites, money offers and untouched starter pages. They describe the sites we’ve found, not every site each builder has made.
