UserAgent Analyzer
Accurately identifies browser, OS, device, and environment features; supports custom UA analysis.
About This Tool
This is a professional UserAgent parsing tool built on the robust ua-parser-js library. It not only quickly identifies your current browser version, rendering engine (e.g., WebKit, Gecko), operating system (e.g., Windows, macOS, Android), and hardware device type but also deeply detects screen resolution, color depth, pixel ratio, timezone, language preferences, and privacy settings like Cookies/DoNotTrack. You can also input any UserAgent string for offline analysis, making it an invaluable assistant for development debugging and environment detection. All analysis is performed locally in your browser to ensure data security.
