JS plugin to detect user's browser, OS, language, geolocation...?
<p>I could have sworn that I saw this on Hacker News a few weeks ago: a simple JS plugin that gives you access to every common bit of information about your user - their OS, browser, language setting, etc.</p>

<p>I'm pretty sure it was a commercial product that was then immediately copied and open-sourced by someone on HackerNews.</p>

<p>But I now can't for the life of me remember what either the commercial product, or the open source plugin, were called. </p>

<p>Can anyone suggest either? </p>

<p>Thanks!</p>
