Open365, an Open Source Alternative to Office 365

Just as LibreOffice is the free, open source alternative to Microsoft Office, Open365 is the free open source counterpart to the cloud-based Office 365.

I have used it for a few hours today and have been really impressed. The good news? It's still in beta. There can only be improvements on the way to release and I wish them all the luck in the world. It shows a lot of promise for a brighter, open source, future.

You can use it for free from https://cloud.open365.io or you can install it on your own server.
