7. Managed Self Hosted Platforms
Self-hosting gives you complete control - and complete responsibility. You'll need hardware that runs 24/7 (electricity costs add up), time for initial setup and ongoing maintenance, skills to troubleshoot when things break, and tolerance for being on-call when your family's movie night gets interrupted.
Now, most of the time everything runs smoothly and you don't need to do anything but there are moments that something might brake. In that case you can call your friends or contact your local Deternet Hub. Now, there are also providers that provide you one click open source app installation and where they handle maintenance, uptime, hardware costs for you.
Now, this is a perfect solution for the use of E2EE open source apps since your data can not be intercepted by the administrators of the servers. However, hosting non E2EE data does put you at a risk and would therefore also not be recommended. In that case you either accept the risk or you better host the mini server yourself at home.
