I really like outliner apps because they incentives to structure notes in an hierarchal fashion. It really helps with problem solving and learning new skills.
I am looking for self-hosted option of outliner apps. I checked and Dynalist and Workflowy dont support self hosted version.
All these apps are effectively copying org-mode features.
Have you tried just using org-mode?
Or did you specifically want a self hosted but online solution on a vps somewhere?
There's vimflowy [1] which which you can try out for yourself using the developers hosting [2] and then if you wish to host if yourself you can using docker [3] . There's also an option to point the developer hosted version at firebase [4] .
