Environment Indicator adds a prominent visual indicator to the WordPress admin bar showing the current site environment. This high-visibility indicator helps prevent accidental changes on production sites by making the environment instantly recognizable to logged-in users.
Perfect for developers, agencies, and teams managing multiple environments (development, staging, production) across different sites.
<h4>Key Features</h4>
Smart Environment Detection 
* Automatically detects environment using WordPress core constants (<code>WP_ENVIRONMENT_TYPE</code>) 
* Supports popular hosting providers: WP Engine, Pantheon, Kinsta, Flywheel 
* Legacy Bedrock constant support (<code>WP_ENV</code>) 
* Subdomain-based heuristics (dev.example.com, staging.example.com) 
* Manual override option for custom setups
Customization Options 
* Custom Colors – Match your branding or personal preferences for each environment 
* Custom Labels – Rename DEV/STAGING/LIVE to LOCAL, UAT, PRODUCTION, or anything you prefer 
* Role-Based Visibility – Control which user roles can see the indicator (great for client sites)
Visual Enhancements 
* Admin bar label (always visible) 
* Full admin bar background coloring (high-visibility option) 
* Browser tab prefix – instantly identify environments across multiple tabs 
* Top border in wp-admin screens 
* Admin footer watermark 
* Dashboard widget showing environment status and system information
Export/Import 
* Export settings as JSON to deploy across multiple sites 
* Import settings from JSON file 
* Perfect for agencies managing client sites with consistent configurations
Multisite Compatible 
* Full support for WordPress multisite installations 
* Network-wide settings when network-activated 
* Per-site settings when activated on individual sites
<h4>How It Works</h4>
Detection runs in this order:
<ol>
<li>WordPress core constant: <code>WP_ENVIRONMENT_TYPE</code></li>
<li>Legacy constant: <code>WP_ENV</code></li>
<li>Hosting provider constants (WP Engine, Pantheon, Kinsta, Flywheel)</li>
<li>Subdomain patterns (dev, staging, test, qa)</li>
<li>Default to LIVE if no detection</li>
</ol>
You can always override automatic detection and manually select the environment.
<h4>Perfect For</h4>
<ul>
<li>Developers – Never accidentally deploy to the wrong environment</li>
<li>Agencies – Manage multiple client sites with consistent environment indicators</li>
<li>Teams – Everyone instantly knows which environment they’re working in</li>
<li>Managed Hosting – Works out-of-the-box with WP Engine, Pantheon, Kinsta, and Flywheel</li>
</ul>
<h4>Zero Impact on Visitors</h4>
The indicator only displays for logged-in users. Public visitors see no performance impact or visual changes.
<h3>Development</h3>
Development of this plugin happens on GitHub: https://github.com/BSolveIT/environment-indicator
