There are so many options. If you’re looking for a free and open source wiki-style setup, a couple I haven’t seen mentioned in the thread yet are Zim Desktop Wiki and Feather wiki (hmm looks like their web certificate is expired at the moment)

I should have thought of that. Thanks! Ironically, I have a very old lead-acid UPS in the basement that I’ve been kind of afraid to plug in again after all this time.

Why removing the battery? I was thinking that could be one good thing about using a laptop is that in a way it has its own UPS.
