Conclusions

On the homepage, Open365 states: "You can download it and deploy to your own servers or use it online for free." This statement, however, is not yet true. Although Open365 bears the word "Open" in its name and uses open source foundations such as LibreOffice, Seafile, and Jitsi, the service's source code is still missing. Without that, it's pretty tricky to host an instance of the service on your own hardware. So, you'll be making your data available with Open365 and are therefore reliant on the provider's goodwill. However, an admin in the forum writes that the provider is working intensively on the release of the source code [9].

Open365 isn't bad in practice. Regardless of the beta status, all the service's components are up and running. Anyone who likes working with LibreOffice and often uses a computer where the Office package is missing will appreciate a readily available Office suite and 20GB of free cloud storage on top in the form of Open365. However, the missing privacy settings are uncomfortably conspicuous: As a user, you should be able to decide whether you want to publish your presence and the plain names of all users of the service.
