This module will help you to keep sane while working on your different environments by adding a configurable color bar to each one of your environments. The Environment Indicator adds a coloured bar on the site informing you which environment you're currently in (Development, Staging, Production, etc.). This is incredibly useful if you have multiple environments for each of your sites, and like me, are prone to forgetting which version of the site you are currently looking at.
This module can help you avoid making configuration changes to your live server by mistake by adding a coloured strip to the side of your site, clearly marking each version of the site.
If you are running 7.x-2.3 or later, then you can show the GIT branch/tag that your site is running. If you are using Acquia cloud make sure you follow the extra instructions.
How to use it.
Read the documentation on how to configure the Environment Indicator.
You can also watch the video (or the video in Spanish) on how to use the environment indicator. These videos talk about the former project Environmental Indicator (a.k.a envindicator) which has become the 7.x-2.x branch, but the principles are the same.
The Environment Indicator's visibility depends upon the permissions of the viewer on each environment allowing a great deal of customization. The module also comes with an environment switcher to open the page you are currently viewing in another environment with just one click.
Environment Indicator Variables
Do you have different variable values for every different environment using
settings.php? You can use the Environment Indicator Variables sub-module for that. It will provide a UI to set the different values per environment that you can export in your features, without polluting your
