I developed tarvis.io which is being used by friends and family to self host notion alternative and run hermes agents. This let's them run self hosted apps as actual apps without having to worry about the server or setups.

One friend was running a gitlab runner on a laptop but moved to tarvis given how easy it is. Tarvis has a catalog of 750 apps already so I am sure you can find a few things from there to run 24/7.

IMO being able to see all the apps in a catalog and being able to easily add that app and experiment helped me figure out which apps I should be running.
