What Plash is

Plash is a free macOS app that puts a website on your desktop as wallpaper, including animated GIFs. You can save multiple websites and switch between them, though only one appears at a time. Browsing Mode lets you interact with the displayed page and use back, forward, reload, and zoom controls. You can change its appearance with custom CSS or JavaScript, inverted colors, reduced opacity, or a transparent background. Plash supports Shortcuts and URL scheme commands for reloading or switching websites, and lists a command-line tool, Alfred workflow, Raycast commands, and a Share extension for adding a Safari website. You can select which display shows the wallpaper, and the app can deactivate automatically when your Mac runs on battery. Plash is listed as free and requires macOS 26.4 or later. It cannot display multiple websites at once or appear on the Lock Screen. Local file URLs are not supported when adding websites through the URL scheme.
