This plugin makes it easy to distinguish between your local development site, and your live site. 
I created this because I often use a local duplicate of my live site, for development, with the same DB, and the same URL.
I needed a quick & easy way of distinguishing between my live and development sites at a glance. This plugin acheives that in the simplest way possible.
There are settings for colour, positioning and the text displayed on the badge. It is also possible to add a link onto the badge.
