Kiwix is nice, I maintained the the wiki server at the South Pole last year. Very useful when internet is down. However the tools are a bit janky and difficult to customise, though they’re being updated at the moment. Odd things like you can’t sort content (if you have say 30 titles) and the built in sort order is based on a random ID string, not content title (why??). I had to write a custom single file webpage with a lot of inline JS to improve things (like sorting elements after load). I also had it pull data from the station intranet so that we could have lots of relevant info in one place, but the only way to do that was to statically generate the page and then restart the wiki server every five minutes… but in the end it's incredibly useful to have that service available and it runs on crappy hardware easily.
