Common UserAgent Query

Tool Introduction

“Common UserAgent Query” is a convenient online tool designed to provide developers, testers, and users who need to simulate different client environments with a comprehensive reference list of PC and mobile device User-Agent strings. This tool collects User-Agents from various mainstream browsers (such as Safari, IE, Firefox, Opera, Chrome) on different operating systems (such as MAC, Windows), as well as User-Agent strings from various mobile devices (such as iPhone, iPad, Android, BlackBerry, Windows Phone). Users can easily browse these User-Agents and quickly copy them to the clipboard with a single click, greatly improving development and testing efficiency.

How to Use

1. Visit the “Common UserAgent Query” tool page.
2. On the page, you will see two main categories: “PC” and “Mobile Devices”.
3. According to your needs, find the specific browser, operating system, or mobile device for which you want to obtain the User-Agent string under the corresponding category. For example, if you need the User-Agent for “safari 5.1 – MAC”, please find this entry under “PC”.
4. Click (or focus on) the text input box to the right of the entry. This action will automatically copy the complete User-Agent string to your clipboard.
5. Now, you can paste the copied User-Agent string into your HTTP request header, browser simulator, or anywhere else you need a User-Agent.
