WP Dev Flag


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.


  • This is what the default badge looks like.
  • This is the Trigger Options tab.
  • This is the Display Options tab.
  • This is the Link Options tab.


From your WordPress dashboard

  1. Visit ‘Plugins > Add New’
  2. Search for ‘WP Dev Flag’
  3. Activate ‘WP Dev Flag’ from your Plugins page.
  4. Visit ‘WP Dev Flag Options’ in the ‘Plugins’ submenu to access the settings.

From WordPress.org

  1. Download ‘WP Dev Flag’.
  2. Upload the ‘wp-dev-flag’ directory to your ‘/wp-content/plugins/’ directory, using your favorite method (ftp, sftp, scp, etc…)
  3. Activate ‘WP Dev Flag’ from your Plugins page.
  4. Visit ‘WP Dev Flag Options’ in the ‘Plugins’ submenu to access the settings.


Can I create my own CSS for the badge?

Currently, you can customise the colour, text and position of the badge. The ability to add a custom class is coming in the next release.

Feel free to just style .wp-dev-flag yourself though.

I will also explore additonal options such as custom fonts & href functionality.

Will the badge display on my live site if I duplicate the entire database as is?

No, it detects the current server environment and if it doesn’t match the environment that was set originally, the plugin will not display the badge. You can simply click update to set the new environment if required.

Can I add a link to the badge?

Yes, as of Version 1.3.0 you can add your own link and toggle it to open in a new tab.

I downloaded the plugin but did not install it when I saw the number of files. It might be great, I won’t say anything on it, I just wanted to share a few lines of code that did the job for me instead: if (defined('WP_DEBUG') and true === WP_DEBUG) { // add a green dot at the bottom left of the screen // when WP_DEBUG in wp-config is true function devTag () { echo '<div style="background:green;border-radius:10px;bottom:20px;height:10px;left:20px;position:fixed;width:10px;z-index: 9999;"></div>'; } add_action('wp_body_open', 'devTag'); }

Installed this on my website when I was developing it, and it’s been a very handy yet simple tool for me. It’s now part of my toolkit for when I am developing WordPress websites.
