Raspberry Digital Signage
Raspberry Digital Signage displays web pages (network-fetched or SD-card-hosted) in a restricted full-screen view. Designed as a cheap and extremely powerful web-based digital signage solution with the Raspberry Pi.

Version 12.1 is a Raspberry Pi 4 compatible build, rebuilt with a Raspbian Buster operating system as its foundation. Some bugs have been fixed as well.

 

Raspberry Slideshow
Raspberry Slideshow is focused on quick-to-set-up image and video slideshows for the Raspberry Pi. It plays all media contained in a USB key, fetched from a network share, from a Web/FTP server, from a folder of your Dropbox account and loaded via scp as well. Designed for media slideshow digital signage.
