Our study did not include v0 or Base44, so this page compares what each builder leaves in a site and what its sites tend to get wrong, not measured outcomes. Scan a site below to see which of the two built it.
| v0 | Base44 | |
|---|---|---|
| Type | AI builder (site written from a prompt) | AI builder (site written from a prompt) |
| Default hosting | v0-*.vercel.app | *.base44.app |
v0How to spot it: Search the page source for generator. If the content is v0.app or v0.dev, it is v0.
What usually goes wrong: Copied and never finished. v0 output is a starting point. Sites shipped straight from it often keep placeholder copy, "Your Company" links and buttons that go nowhere, which reads as unfinished to a visitor.
Base44How to spot it: Look at the address: *.base44.app is Base44 hosting.
What usually goes wrong: The app shell is empty for crawlers. Base44 renders everything in the browser. Search engines and link previews see a page with no text, so the description you wrote in the editor may be all that reaches them.
Usually, yes. Each leaves its own traces: v0 on v0-*.vercel.app and in its scripts, Base44 on *.base44.app and in its own markers. Paste the URL in the scanner above and it names the builder with the evidence it found.
Neither decides it alone. What matters is whether the finished page has a real heading, a meta description and content that search engines can read without running JavaScript. Scan your site to check those.
Not by being AI-built. The problems we see most are defaults nobody changed: titles, badges, blocked zoom, and database keys used without access rules. Each is a short fix once you know it is there.
