Anyone who owns a website can be a contributor and help me grow the database of user agents. To do this, add the following snippet to your site (I recommend adding it before "</body>"):

<img src="//partners.user-agents.net/stats/1x1.gif" alt="1x1" />

Or use the following snippet if you want to embed the image asynchronously:

<script>(new Image).src='//partners.user-agents.net/stats/1x1.gif'</script>

This fragment will embed a 1×1 transparent image on your web page. This microscopic image will not have any effect on the design or performance of your page. If you have any questions, please contact me.
