User Agent Parser
Decode user-agent strings into browser, operating system, rendering engine, and device type. Useful when reviewing logs or analytics entries.
How to Use
- Paste a user-agent from logs, analytics, or request headers.
- Click Parse.
- Review browser family, engine, OS, and device type.
For HTTP response troubleshooting while inspecting requests, use the HTTP Status Code Lookup.
When UA Parsing Is Useful
- Support tickets: Confirm whether an issue is browser-specific.
- Analytics audits: Spot unusual device mixes or bot-like traffic signatures.
- Compatibility testing: Prioritize browsers your users actually run.
Important Limitations
User-agent strings are not always trustworthy. Some clients spoof browser identity, and modern privacy protections may reduce detail. Use parser output as a diagnostic hint, not a security signal.
FAQ
Is user-agent parsing always exact?
No. Some strings are spoofed or intentionally generic, so results are best-effort.
Can this identify bots?
Only partially. It may surface obvious bot signatures, but reliable bot detection needs additional request metadata.
Does this send UA strings to a server?
No. Parsing happens in the browser and does not upload your input.
