Dev Favicon Switcher helps you easily distinguish between your production and development environments. It automatically displays a different favicon based on the current URL, avoiding mistakes where you might accidentally edit the live site thinking it’s the development environment.
Key Features:
<ul>
<li>Automatic Environment Detection: Automatically applies the development favicon on common local domains (<code>.local</code>, <code>.test</code>, <code>.dev</code>).</li>
<li>Custom Development URLs: Specify exact URLs where the development favicon should appear (supports multiple URLs).</li>
<li>Easy Icon Management: Upload your own dev favicon using the WordPress media uploader, complete with built-in image cropping.</li>
<li>Restore Default Icon: Don’t have an icon handy? Easily apply our unified default development favicon with a single click.</li>
<li>Automatic Size Generation: Automatically generates all standard WordPress site icon sizes (32×32, 180×180, 192×192, 270×270) to ensure compatibility across all devices and browsers.</li>
<li>No Frontend Bloat: Everything works efficiently via standard WordPress filters without adding unnecessary frontend scripts.</li>
</ul>
Perfect for developers working with local environments, staging servers, and migration tools like All-in-One WP Migration.
