About the User-Agent Parser
Every HTTP request sent by a browser or bot includes a User-Agent header describing the client's software, rendering engine, and operating system. However, real-world User-Agent strings are notoriously cryptic and bloated with legacy tokens for backwards compatibility. This User-Agent Parser extracts clear, structured device and browser data from any UA string.
This tool is useful for web developers debugging cross-browser rendering issues, analytics engineers classifying web traffic, and cybersecurity specialists analyzing access logs. It detects the Browser (Chrome, Safari, Firefox, Edge, Opera), Browser Version, Operating System (Windows, macOS, iOS, Android, Linux), Device Type (Desktop, Mobile, Tablet, Bot), and Rendering Engine (Blink, WebKit, Gecko).
To use the tool, paste a User-Agent string into the box or click 'Use My Browser's User-Agent' to inspect your current device. Click 'Parse User-Agent' to view the breakdown.
For example, a UA string from an iPhone is identified as Apple Safari running on iOS Mobile with the WebKit engine.
A common misconception is that User-Agent strings are guaranteed to be authentic. User-Agents can be customized or spoofed by bots, HTTP clients, and privacy extensions, so critical security checks should not rely solely on UA strings.
Tip: Use the 'Use My Browser's User-Agent' button to quickly verify what information your browser broadcasts to websites you visit.
