What does the user agent parser tell me?

Paste a user agent string and it identifies the browser, the operating system and the device type. For example, a Chrome string from a Windows PC is read as Chrome, Windows, Desktop.

Where do I find my own user agent string?

Most browsers expose it through their developer tools console as navigator.userAgent, and many sites echo it back to you. Copy that value and paste it into the box to see the breakdown.

Why does the device show as Desktop for my phone?

The result depends entirely on the text in the string. If a mobile string is missing the usual phone or tablet markers, it can read as Desktop. Paste the exact string your device sends for an accurate result.

Is my user agent string sent anywhere?

No. Parsing happens entirely in your browser. The string you paste never leaves your device and nothing is logged or uploaded.

What the User Agent Parser does

The User Agent Parser reads a raw user agent string and tells you the three things that actually matter: which browser it represents, which operating system it came from, and whether the device is a desktop, phone or tablet. Drop in one of those long, cryptic strings and you instantly see a clean summary instead of squinting at version tokens and parentheses.

It helps web developers, QA testers and support staff who need to understand what a visitor was using. When a bug report includes a user agent string, you can paste it here and know in seconds whether the issue came from Chrome on Windows, Safari on an iPhone, or something else entirely.

How to use it

Paste a full user agent string into the input box. For example Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0 Safari/537.36.
Press the Parse button.
Read the detected browser, operating system and device type in the output box.
Hit Copy to grab the result for your notes, ticket or bug report.

A quick tip: the detection is only as good as the string you paste, so copy the exact value from the device or log you are investigating rather than typing it from memory.

Why parse user agents here

It is fast, with the answer appearing the moment you click and no server round trip. It is private, since everything runs locally in your browser and the string you paste stays on your device. And it is free, with no account, no install and no sign-up. Open the page, paste a string, get your answer.
