Raw JSON
{
"ua": "",
"browser": {},
"cpu": {},
"device": {},
"engine": {},
"os": {}
}Your data never leaves the browser.
How it works
- Paste a UA string or use yours.
- See browser, OS, and device fields.
- Copy JSON if you need the full parse.
FAQ
- Is parsing perfect?
- UA strings are heuristics — results are best-effort.
- Sent to a server?
- No. Parsing is local via ua-parser-js.
