How it works & limitations

• One request per URL (plus robots.txt). The page HTML, scripts, headers, cookies and meta tags are matched against technology fingerprints.
• No JavaScript execution, so tools that only appear after scripts run in a browser may be missed. In exchange it is fast and cheap.
• Detection is based on public fingerprints and can occasionally include false positives; each result has a confidence score.
