About User Agent Parser
Parse common browser, operating-system and device hints from a user-agent string. This browser utility is designed for a focused practical task without requiring a separate installed application.
How to use User Agent Parser
- Read the input labels and enter the requested values or content.
- Select any units, modes or options that apply to your task.
- Run the tool and review the result, warnings and assumptions shown on the page.
- For important decisions, independently verify the output against an authoritative source or accepted method.
Method, formula or processing logic
Check units, assumptions and source data before relying on the result.
When this tool is useful
- Diagnosing a public DNS or network issue.
- Checking public host information.
- Verifying configuration after a technical change.
Understanding the result
Read the displayed result together with the input units, selected options and any warnings generated by the tool. A mathematically valid output can still be unsuitable if the source data, units or assumptions do not match the real problem. For academic, engineering, financial, medical, legal or publication-critical work, independently verify important results against an authoritative source or accepted professional method.
Privacy and processing
Most inputs are processed directly in the browser. A tool that explicitly checks a public website, DNS record, network endpoint or translation service may send the minimum required query to that public endpoint to obtain the requested result.
