If you’re like me, you often have multiple versions of the same WordPress site open in different browser windows, e.g., production in one window and development in another window.
And if you’re like me, you have also unwittingly edited content in the production environment thinking you were doing so in the development environment or vice versa.
If so, then this plugin is for you!
It adds an indication of the current environment to the Admin Bar that is easier to see than examining the URL in your browser’s address bar.
<h3>Out-of-the-box behavior</h3>
Out-of-the-box, 2 different environments are recognized:
<ul>
<li>Production
<ul>
<li>The node added to the Admin Bar has a red background (i.e., Stop/be careful with any changes you make).</li>
<li>If neither a staging, QA, nor development environment is detected, then <code>Prod</code> is displayed in the Admin Bar.</li>
</ul>
</li>
<li>Development
<ul>
<li>The node added to the Admin Bar has a green background (i.e., Go ahead, it is safe to make changes).</li>
<li>If WP is running on localhost (either a loopback IP address or LAN IP address), then <code>Local</code> displays in the Admin Bar.</li>
<li>If WP_DEBUG is defined & true, then <code>Dev</code> displays in the Admin Bar.</li>
</ul>
</li>
</ul>
<h3>Customizing the out-of-the-box behavior</h3>
Two additional environments are supported, but cannot be automatically detected:
<ul>
<li>Staging
<ul>
<li>The node added to the Admin Bar has a yellow-ish background (i.e., Slow down, changes might make it into the production site).</li>
<li>For information on how to enable this environment, see the <a href="https://github.com/pbiron/shc-show-env/" rel="nofollow ugc">documentation</a>.</li>
</ul>
</li>
<li>QA
<ul>
<li>The node added to the Admin Bar has a blue background (i.e., “It’s cool”, changes you make won’t affect the production site).</li>
<li>For information on how to enable this environment, see the <a href="https://github.com/pbiron/shc-show-env/" rel="nofollow ugc">documentation</a>.</li>
</ul>
</li>
</ul>

Show Environment in Admin Bar

Super handy if you are click-happy with your mouse like me. Red "Prod" badge in admin bar is effective way to prevent you from accidentally messing up the production

Essential plugin when working in multiple environments

I'm like the author. I sometimes change admin color, but can never remember what color I set for Prod vs Dev.

Useful for developers like us

Add an indication to the Admin Bar of the environment WordPress is running in (e.g., Prod, Staging, QA, Dev, etc).
