User-Agent Parser
Parse a user-agent string into browser, OS, and device hints.
About this tool
Raw user-agent strings are noisy. This free UA parser breaks them into browser, OS, and device hints so log lines make sense. Paste a UA from analytics or support tickets, parse locally, and spot bot or legacy-browser issues faster.
How to use
- Paste the user-agent string from logs or headers.
- Parse to view browser, OS, and device fields.
- Use the structured result while debugging.
- Remember UAs can be spoofed—treat them as hints.
Frequently asked questions
No. Clients spoof UAs and formats change. Use as a best-effort signal alongside feature detection.
