Plash enables you to have a highly dynamic desktop wallpaper. You could display your favorite news site, Facebook feed, or a random beautiful scenery photo. The use-cases are limitless. You could even set an animated GIF as wallpaper. You can even add multiple websites and easily switch between them.
Requires macOS 14 or later.

Non-App Store version
A special version for users that cannot access the App Store. It won't receive automatic updates. I will update it here once a year.

You can interact with the website by enabling “Browsing Mode”. When in this mode, you can right-click to be able to go back/forward, reload, and zoom in the page contents (the zoom level is saved). You can also pinch to magnify. This is different from zooming the page contents in that it will zoom in to a specific part of the page instead of just enlarging everything.
Plash injects a CSS class named plash-is-browsing-mode
on the <html>
element while browsing mode is active. You could use this class to customize the website for browsing mode.
If clicking a link opens it in a new window, you can hold the Option key while clicking the link to open it in the main Plash window.
To zoom in the website, activate “Browsing Mode”, right-click the website, and then select “Zoom In”.
Use [[screenWidth]]
and [[screenHeight]]
in any URL and Plash will substitute the right values for you. For example, https://source.unsplash.com/random/[[screenWidth]]x[[screenHeight]]?puppy
.
You can scroll a website to a specific position each time it is loaded by putting the following in the website's “JavaScript” field. Adjust the “500” to how far down it should scroll.
window.scrollTo(0, 500);
You can also scroll to a specific element matching a CSS selector:
document.querySelector('.title')?.scrollIntoView();
You can use the “CSS” field in the website settings to adjust the padding of the website:
:root {
margin-left: 50% !important;
}
Plash injects a CSS class named is-plash-app
on the <html>
element. You could use this class to customize your website for Plash. For example, if your website has instructions on how to use it in Plash, you could hide those when it's running in Plash.
You can control Plash using anything that supports opening a URL with a custom scheme.
For example, to reload the current website, run this terminal command:
$ open -g plash:reload
Plash comes bundled with a share extension. You can, for example, use it to quickly add a website you have open in Safari to Plash.
add
Add a website to Plash.
You can optionally specify a title. If no title is given, a title will be automatically fetched from the website.
$ open -g 'plash:add?url=https://sindresorhus.com/plash&title=Plash%20website'
Don't forget to correctly encode query parameters.
Note: Local file URLs are not supported.
reload
Reload the current website.
$ open -g plash:reload
next
Switch to the next website in the list.
$ open -g plash:next
previous
Switch to the previous website in the list.
$ open -g plash:previous
random
Switch to a random website in the list.
It will never show the same website twice in a row, unless you only have a single website.
$ open -g plash:random
toggle-browsing-mode
Toggle browsing mode.
$ open -g plash:toggle-browsing-mode

macOS hides menu bar apps when there is no space left in the menu bar. This is a common problem on MacBooks with a notch. Try quitting some menu bar apps to free up space. If this does not solve it, try quitting Bartender if you have it installed.
Plash can be automated with the built-in Shortcuts app, for example, using the “Switch to Next Website” action. Shortcuts on macOS does not yet support automations, but for now, you can use the Shortery app.
Support for multiple displays is currently limited to the ability to choose which display to show the website on. Support for setting a separate website for each display is planned.
However, I there is a workaround.
Plash uses very little memory. Usually around 40 MB. However, the websites you display can take up a lot of memory, and sometimes even have a memory leaks.
The menu bar adapts its color from the actual system wallpaper. Plash is not actually a wallpaper, but rather runs right above the wallpaper. So Plash cannot influence the menu bar color.
Not built-in, but you can block ads system-wide with a DNS ad-blocker.
Make a shortcut in the Shortcuts app that uses the “Set Current Website” action and then set a keyboard shortcut for the shortcut.
I don't have any immediate plans to localize the app.
