How to use User-Agent Parser
Paste a UA string or use your current browser UA. Parsing is heuristic and runs locally.
Understanding the results
Parsed fields are best-effort hints from the UA string, not a guaranteed device identity.
Limitations
- Modern browsers may reduce or freeze UA detail.
- Parser results are heuristic.
Privacy note
Parsing runs locally in your browser.
