Plash review
A free Mac utility for interactive, automated website-based desktop backgrounds.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Plash is a free macOS utility that displays remote or local websites above the desktop wallpaper. It is designed for Mac users who want informational, interactive, or animated backgrounds, including calendars, feeds, images, animated GIFs, and custom-built pages. Browsing Mode lets users interact with displayed websites, while saved websites make it possible to switch between multiple background choices.
The Free plan includes the macOS utility and unlimited web access. Its feature set covers automatic reloads at a custom interval, selected-display output, opacity and color adjustments, transparency controls, and automatic deactivation while on battery. Custom CSS and JavaScript add control for users who want to tailor how a page appears or behaves. This makes Plash more suitable for web-based dashboards and custom pages than for selecting from a conventional wallpaper collection.
Automation is a central part of the product’s fit within the Mac ecosystem. Plash supports Shortcuts and URL commands, includes a bundled Safari share extension, and integrates with Alfred and Raycast. Multi-display support lets users choose which display shows the website, but separate websites per display are not supported. Users looking for one interactive web background across a selected display, with reload scheduling and automation options, should find the scope well defined. Those who want distinct wallpaper content on every monitor or a broader general-purpose wallpaper library should choose a different type of desktop wallpaper software.
