How Tech Stack Detector detects v0
v0 is matched from these signals during a single, ordinary page request. Each one contributes to the confidence score shown on a scan.
- TemplateGenerator meta tag set to v0
- TemplateDefault "Created with v0" description
- TemplateDefault "v0 App" page title
Platform evidence comes from v0's own hosting or runtime and gives a Confirmed result. Template evidence is left in the code v0 generates and gives a Strong evidence result, because an owner can edit it out. See how accurate the AI builder check is

What is v0?
v0 is an AI app builder: Generative builder by Vercel that turns prompts into Next.js apps and user interfaces. Tech Stack Detector identifies v0 on any website by analysing the generator meta tag and the HTML source. Its official website is https://v0.app.
How can I tell if a website uses v0?

Can a website hide that it was built with v0?
v0 websites are recognised from tags in the code that v0 generates. After the code is exported and hosted elsewhere, only the tags left in the generated source remain, and an owner can delete those too. In that case Tech Stack Detector reports no evidence instead of guessing.
