WP-UserAgent is a simple plugin that allows you to display details about a computer’s <a href="http://en.wikipedia.org/wiki/Operating_system" rel="nofollow ugc">operating system</a> or <a href="http://en.wikipedia.org/wiki/Web_browser" rel="nofollow ugc">web browser</a> that your visitors comment from.
It uses the comment->agent property to access the <a href="http://en.wikipedia.org/wiki/User_agent" rel="nofollow ugc">User-Agent string</a>. Through a series of regular expressions, this plugin is able to detect the operating system and browser which can be integrated in comments or placed in custom places through your template(s).
I’m adding new web browsers and operating systems frequently, as well as updating and optimizing the source code. Your feedback is very important, new features have been added by request, so if there’s something you would like to see in WP-UserAgent, <a href="https://www.kyleabaker.com/goodies/coding/wp-useragent/" rel="nofollow ugc">leave a comment</a>, and I’ll see what I can do.

<h3>Features</h3>
<ul>
<li>Detects most web browsers and popular operative systems (if you find one missing, please <a href="https://www.kyleabaker.com/goodies/coding/wp-useragent/" rel="nofollow ugc">let me know</a>!)</li>

<li>Easy standard installation, just upload to wp-plugins and activate it.</li>
<li>Customizable options.</li>
<li>No basic knowledge of PHP or editing WordPress templates required.</li>
