And Qwant is really great! Have been using og for a couple of years, and have no need to fall back to Google, DDG etc.

It has RSS built-in, but since it is a static site generator, it does not support ActivityPub out of the box. But I do think I have seen implementations with some custom JavaScript.

I use Navidrome, it’s a single binary and gives you your own Spotify, kinda. It can be use with many other apps, in addition to the web interface, as it supports the subsonic protocol.
