Mobile User-Agent Parser

Summary

The Mobile User-Agent Parser dissects any HTTP user-agent string to reveal the device type, operating system, browser name and version, and rendering engine. It works entirely in your browser — no data is sent to any server. Paste a UA string or click "Detect My UA" to analyze the current browser automatically.

How it works

1. Auto-detect your current browser UA or paste any UA string into the input field.
2. Click "Parse" (or press Enter) to trigger the client-side parser.
3. The tool runs a series of regex patterns to identify device type, OS, browser, and engine.
4. Results appear instantly in a structured card layout with confidence indicators.
5. Copy individual fields or the full parsed JSON for use in your code.

Use cases

• Debug mobile-specific issues by checking exactly what your device reports.
• Test UA string parsing logic for web apps and APIs.
• Verify bot vs. human traffic classification during development.
• Identify legacy browsers or OS versions in support tickets.
• Cross-check UA strings from server logs.
• Build UA allowlists or blocklists with accurate detection data.
