A lot of schools and businesses use the free Chrome Sign Builder created by Google, which, because it is a Chrome App, is slated to be deprecated by the middle of 2026 (except for long-term support). I used Google Gemini 3 Pro to vibe code an alternative in about an hour, which is suitable for organizations that use Google Slides as the “meat and potatoes” of their slide presentation, and used Chrome Sign Builder as a wrapper. Feel free to use this yourself and customize it as you see fit, and share it to anyone else that might find this useful.
Go to the project page to view the code and instructions on how to deploy it.
The code creates a digital signage display that layers a clock, weather information, and a QR code over a Google Slides presentation. It also includes a background music player.
