What are the pros and cons?

These comparisons are extremely difficult to make (not many people really tried all, we all judge from docs, etc.) That being said, I think runtipi is simpler in the curve of customization, if you have the knowledge. If you don't, well then maybe, a full-blown OS is better. But my original post addressed the advantage I see on runtipi, with all the links to the docs. It's powerful and encourages customization. To me, it's a good mid-point between 'raw' docker (e.g. linuxserver.io which btw provides most of the images), and a highly automatized system. For example, one of the bigger features is that you can set repositories (e.g. on GitHub) as stores: I will repeat the link to these docs here: https://www.runtipi.io/... ..over these repos you simply write docker-compose YAML files. I don't know what's the solution to this on CasaOS, but YunoHost has a set of scripts or bash functions. That's something I believe takes more effort to mantain. All in all, imho, runtipi has a good balance between flexibility, complexity, and customization.
