Introduction to the sandstorm :
Sandstorm is a self-hostable web productivity suite. It's implemented as a security-hardened web app package manager.
Sandstorm lets you run your own server and install apps like EtherCalc, GitLab, Etherpad, Wekan, Framadata (doodle-like app) and more as easily as you'd install apps on your phone. Sandstorm handles login & access control, and can run any web app that runs on Linux, though some apps may need changes to work within the Sandstorm sandbox.
Sandstorm is very new and a lot of features have yet to be developed; however, many people are already using it for real work every day.
