Datasette is a neat tool intended to publish static data in a sqlite database on the web with a helpful gui and a bunch of extensions available. I havent come across a good enough reason to do it myself, but may do what you want.
You can spin it up locally and it wont be on the web at all, just accessed via your browser if thats what you want.
Server is running the password manager for myself and family, and that needs to stay on while gone (there are ways of handling local copies and they sync later, but when ive accidentally had to troubleshoot that it sucks).
Then ive got nextcloud, which while i don’t normally need things on there i do enough that it is nice to have.
