I use Dokuwiki: https://www.dokuwiki.org/

I access it when I'm out and about, but do so through a VPN that I also run from my home. The wiki is not accessible except through the VPN.

Organizationally, I have a different section for general aspects of my life (household, programming, and hardware projects as well as hobbies such as camping, etc.). The front page is a general catch-all where I temporarily drop things that don't already have a home. I then organize them more formally later.

I make pretty heavy use of inter-page links to help organization of related things that aren't in the same "world". A lot like note-taking apps.
