I’ve made startpages for myself. (Current one I’m using can be seen here.)
If it counts I have a offline personal wiki set up for my OCs. I never really use it anymore & should probably work on it again. 
I also made a character randomizer for when I don’t know what to draw, which failed spectacularly as I forgot about it. 
Might have to somehow add it to a startpage or something so I actually use it.
Wiki ramblings:
I might end up removing it or storing it externally since it’s using mediawiki & I’m not using it often enough to warrant keeping it. Might use dokuwiki instead since it’s smaller & the articles are easier to backup if I recall correctly. Wish I could figure out how templates work, I’d probably make a custom one for myself that fits my interests since a ton of them aren’t really my thing.
