I have been using Brave Search for over a year and have been very pleased with the results. I have also seen a lot of good things about Kagi, but it does require a subscription.

I have had positive experiences with both Radicale and Baikal. I am not sure about the Home Assistant integration, but they both use CalDAV, so I would be surprised if there wasn’t a way of connecting them. iOS has native support for CalDAV, but Android needs the davx5 app (free on F-Droid).

Oregon. I have only ever heard them called weed eaters.

I just run some simple services such as Audiobookshelf or Wallabag behind a reverse proxy. After reading the other comments, it does not look like there would be any benefit for my use case.

Yes, I have always used a reverse proxy which seems to eliminate the need for multiple IP addresses. It seems like having multiple IP addresses just creates additional cost and complexity, but I have seen many VPS providers offer multiple IP addresses, so I was curious if there was a use case that I was not aware of.

LibreOffice and OnlyOffice are both compatible with MS Office formats. LibreOffice is more popular, but OnlyOffice has better compatibility with MS Office files and the interface is very similar as well.

DokuWiki. Everything is a text file that can just be copied to a web server. It doesn’t even require a database. And since all the wiki pages are plaintext markdown files, they can still be easily accessed and read even when the server is down.
