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:** * **Automatic Environment Detection**: Automatically applies the development favicon on common local domains (`.local`, `.test`, `.dev`). * **Custom Development URLs**: Specify exact URLs where the development favicon should appear (supports multiple URLs). * **Easy Icon Management**: Upload your own dev favicon using the WordPress media uploader, complete with built-in image cropping. * **Restore Default Icon**: Don’t have an icon handy? Easily apply our unified default development favicon with a single click. * **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. * **No Frontend Bloat**: Everything works efficiently via standard WordPress filters without adding unnecessary frontend scripts. Perfect for developers working with local environments, staging servers, and migration tools like All-in-One WP Migration. Development Source: This plugin is developed using npm and webpack. You can find the human-readable source code and build tools in our public repository: https:// github.com/karasunouta/dev-favicon-switcher ## Screenshots * [[ * The plugin settings screen where you choose your development icon. * [[ * The default dev favicon already active in browser tabs immediately after activation— no setup required. * [[ * Clicking “Select Dev Favicon” opens the Media Library popup to choose a custom image. * [[ * Cropping the selected image to a square before setting it as the dev favicon. * [[ * The cropped image reflected in the settings screen and automatically applied in the browser tab bar. ## Installation 1. Upload the `dev-favicon-switcher` folder to the `/wp-content/plugins/` directory. 2. Activate the plugin through the ‘Plugins’ menu in WordPress. 3. Configure the plugin by going to **Settings > Dev Favicon**. ## FAQ ### Does this modify my actual production site? No. The plugin only overrides the favicon URL dynamically when it detects that you are accessing the site via one of your configured development URLs (or auto-detected extensions). Your live site will continue to load its normal configured site icon. ### How does the auto-detect feature work? If enabled, the plugin checks your current domain. If it ends with `.local`, `.test`, or `.dev`, it automatically considers the environment a development one and switches the favicon. ### What if I don’t have a specific development favicon to upload? You can simply click the “Restore Default” button in the settings, and the plugin will apply a built-in default development favicon for you. ### Does it support image cropping? Yes! When you upload or select a new development favicon from the media library, the plugin provides a cropping tool just like the native WordPress Site Icon feature. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Dev Favicon Switcher” is open source software.
