What Is ScreenPlay and What Can You Use It For?

Updated

ScreenPlay is a free, open-source desktop app for Windows and macOS that displays live wallpapers and desktop widgets. You can use it to run video, HTML5, QML, or GIF wallpapers behind your icons, and to place small helper widgets—CPU usage, time, weather, or Reddit threads—directly on the desktop. It is built with modern C++20/Qt6/QML, and the official binaries with Steam Workshop support are distributed through Steam for Windows and macOS, with Linux/KDE listed as coming soon.

What ScreenPlay actually does

ScreenPlay has two main jobs, and both run on the desktop rather than inside a browser tab.

Live wallpapers

The wallpaper layer supports a broad range of formats: most video formats, HTML5, QML, and GIF. That means you are not limited to looping MP4 files—interactive or animated content written in QML can also run as a wallpaper.

Desktop widgets

Widgets are small helper apps pinned to the desktop. The site names CPU usage, time, weather, and the latest Reddit threads as examples. This is aimed at people who would otherwise keep several small apps or browser tabs open just to glance at information.

Key features and what they mean in practice

Feature What it gives you
Free & open source Source is public; the project describes transparency, security, and accessibility as its goals, and welcomes community contributions
Cross-platform Windows and macOS binaries; Linux/KDE is listed as soon to come
Apple Silicon support (V0.15) Universal Binary works on both Intel and Apple Silicon Macs at full speed
QML/JS scripting A declarative language for building custom wallpapers and widgets, with native ECMA 2017 support for interactive and animated content
Live reloading Code hot reload shows your changes in real time, so you do not restart content after every edit
SysInfo API Exposes CPU usage, memory usage, and IP address—useful for power users, developers, and sysadmins monitoring system stats
Weather Forecast API (V0.15) Built around open-meteo.com, providing a detailed 7-day forecast plus matching weather icons
Steam Workshop A large library of user-uploaded content you can browse and install

Who it suits

  • People who want a live desktop without paying for Wallpaper Engine-style software. ScreenPlay is explicitly free and open source.
  • Mac users on Apple Silicon. The V0.15 release adds Universal Binary support, so M-series Macs run it natively rather than through translation.
  • Tinkerers and developers. QML/JS scripting plus live reloading makes it practical to build your own wallpaper or widget and iterate quickly. The SysInfo API is a ready-made data source if you want a system-monitor widget.
  • Anyone who wants at-a-glance desktop info. Weather, time, and CPU widgets replace opening separate apps.

It is less of a fit if you want a purely click-and-install experience with no interest in customization—though the Steam Workshop library covers that case for wallpapers.

How to get started

  1. Install via Steam. The site points to Steam as the primary download for Windows and macOS, and this is the build with Workshop support. Other download options are listed on the site's Download page.
  2. Pick a wallpaper. Choose from the Workshop or load your own video, HTML5, QML, or GIF file.
  3. Add widgets. Place the built-in widget types (CPU, time, weather, Reddit) on the desktop.
  4. Optional: build your own. Write a QML/JS project, use live reloading to preview changes as you edit, and pull system data through the SysInfo API or forecast data through the Weather API.

Things to check before committing

  • Platform coverage is not complete. Windows and macOS have Workshop-enabled binaries; Linux/KDE is described as coming soon, so Linux users should not expect a finished build yet.
  • Steam is the main distribution channel. If you prefer not to use Steam, review the "Other Download Options" on the site before installing.
  • Widget data sources matter. The weather widget depends on open-meteo.com, so forecast accuracy and availability follow that service.
  • Custom content requires learning QML. The site calls QML easy to learn, but building interactive wallpapers is still a scripting task, not a settings toggle.

In short: ScreenPlay is a free, open-source alternative for live wallpapers and desktop widgets on Windows and macOS, with a strong customization path through QML and the Steam Workshop as its content ecosystem.
