Before Dawn

Before Dawn is a free, open-source screensaver application that lets users design custom screensavers using standard web technologies like HTML, CSS, and JavaScript. Built on the Electron framework, this cross-platform tool offers a smooth and flexible desktop experience. Creating a screensaver is as simple as building a web page, making it accessible for those with basic coding knowledge.

The app runs quietly in the background and activates screensavers based on user-set idle times, helping keep your desktop visually appealing during inactivity. Installation is straightforward, with versions available for Windows and Mac OS X, and an experimental release for Ubuntu/Debian.

After installation, a user-friendly preferences window lets you preview, choose, and customize screensavers with ease. While it's especially useful for experienced web developers, the intuitive interface also allows beginners to try their hand at creating unique and personalized screen visuals—making Before Dawn a great addition to any desktop.
