Sandstorm is an open source operating system for personal and private clouds at .
WebApps like Wekan, Rocket.Chat etc have been ported to Sandstorm, to use integrated Single Sign-On login and other security features, so there can be differences in original and Sandstorm port features.
You can install it to your own x86_64 Ubuntu server and with webbrowser click and install Open Source webapps from Sandstorm webappstore.
It's also possible to use hosted version at project website, with some free space, and optional paid features.

NOTE: This Open Source project is not related in any way to Darude Sandstorm music.
