Fingerprints, not confessions

Every detection Isvibe.io reports comes from public technical signals in a page's shipped output: generator meta tags, script and asset paths, hosting headers, component class patterns, and backend-as-a-service endpoints. We do not have access to any builder's internal records.

Not an official statement

Naming a tool — v0 by Vercel, Bolt.new, Lovable.dev, Replit Agent, or any other — identifies a pattern we matched. It is not a statement from, endorsement by, or confirmation from that company. Isvibe.io is not affiliated with Vercel, StackBlitz, Lovable, or Replit, and tool names are used for identification purposes only.

Results are probabilistic

A high Vibe Score means many fingerprints fired, not that a page was definitively generated by AI. A low score means we found nothing, not that a human wrote every line. False positives happen when a team hand-builds on the same stack an AI builder favors; false negatives happen when generated code is refactored, self-hosted, or served through a proxy.

Use it accordingly

Read the evidence list, not just the number. Treat a score as one input into your own judgement, and never as the basis for an accusation about a person, agency, or company.
