Parse browser User-Agent strings to identify browser, OS, and device information.

User-Agent Input

Usage Guide

Features

Parse browser User-Agent strings to identify browser name, version, render engine, operating system, device type, and more. Support one-click retrieval of current browser UA and real CPU architecture via Client Hints API.

Steps

Click "My UA" to auto-fill the current browser User-Agent, or click "Sample" to load a preset UA, then click "Parse" to view browser, OS, and device information in the cards below.

Notes

User-Agent can be spoofed and should not be used as the sole basis for security verification; macOS UA strings always contain "Intel". Clicking "My UA" uses Client Hints API for real architecture (Chrome/Edge only); other browsers or manually entered UAs show architecture as unknown.
