Paste a User-Agent string from a request log, browser dev tools, or an app's network traffic, and see it broken down into browser, rendering engine, operating system, device, and CPU architecture — no more squinting at a wall of version numbers.
Frequently asked questions
Why do some fields show 'unknown'?
Not every User-Agent string includes every field — for example, most desktop browsers don't report a device vendor or model, since that's mainly relevant for phones and tablets.
Can User-Agent strings be trusted?
Not fully — a User-Agent is just a string the client chooses to send, and it can be spoofed or blocked entirely (many privacy-focused browsers normalize or randomize it). Treat parsed results as a hint, not a guarantee.
