Hey everyone,
People are making perfect websites using AI builders like v0, Lovable, Bolt and other AI website builders these days.
Whenever I spotted a slick landing page, I kept wondering if it was built by an AI website builder or hand-crafted/vibe-coded, with no easy way to tell. So I built a quick tool to handle it.
Paste a URL, and it instantly scans to identify if an AI website builder was used.

As AI-generated sites become harder to distinguish visually, the challenge will be identifying reliable signals beyond surface-level patterns.
