Is there an Open Source solution similar to Dropbox to install at home?

Question

Computer networks

I want to install some solution for file sharing, only with a convenient drag-and-drop interface. If there are clients for mobile devices, great.
The main focus is on the web interface, so that there is an admin panel for users, with statistics on volume, traffic, etc.
Thank you.
