It can be rather painful to host e.g. nextCloud: you have to download and install the software. On Dropbox, you just register and Bob’s your uncle. What libre.sh wants to do is to give one-click hosting for free software. The user just clicks a button to launch a container with that package.
Even setting up a cloud service provider is very easy with libre.sh. During the talk a demo was given but documentation is available as well. It relies heavily on Docker to manage the containers.
What is definitely missing is single sign on, so you don’t have to create a new admin account for every service.
This was followed by a talk on puffin.rocks, which looks very similar.
