My User-Agent

Find your User-Agent and parse any browser string online

Your browser sends the User-Agent with every request, and sites read the browser, OS and device from it. Below is your string with a breakdown. Paste another one to check it.

Breakdown

Client Hints from your browser

Chromium browsers hand these to a site on request. They reveal Windows 11, the phone model and the full browser version.

What a User-Agent is made of

Almost every browser starts the string with Mozilla/5.0, a leftover from the nineties. The brackets hold the OS and platform, then come the engine and the browser version.

Since 2022 Chrome, Edge and other Chromium browsers trim the User-Agent: Windows 11 looks like Windows NT 10.0, and the Android version and phone model are hidden. Sites get the exact data through Client Hints.

Who needs it

Scraper developers who need a real browser string.
People setting up an antidetect browser who match the User-Agent to the OS.
Admins going through server logs and looking for bots.
Support teams who need the client's browser and OS.

Questions and answers

01Can I change my User-Agent?

Yes. In Chrome, open DevTools, Network conditions, User agent. For a permanent swap, use an extension or an antidetect browser. Keep the platform, Client Hints and fingerprint in line with the new string, or the anonymity check will show a mismatch.

02Why does Windows 11 show as Windows 10?

Chromium browsers froze the string at Windows NT 10.0. Only Client Hints tell Windows 11 apart: its platform version is 13 or higher. This page uses it when your browser provides it.

03Which User-Agent should a scraper use?

A current Chrome or Firefox string for the same OS as your server. Change it together with Accept-Language and sec-ch-ua so the requests look consistent.

04What are Client Hints?

The sec-ch-ua headers in which Chrome reports the brand, version and platform apart from the User-Agent. A site can request details such as the exact OS version. When the hints contradict the User-Agent string, the swap shows.

05How do I tell a real search engine bot?

A Googlebot or YandexBot string is easy to fake, so check the IP. The PTR of a real Googlebot ends in googlebot.com or google.com, and the A record of that name returns the same address.
