Oh wow I didn't know that. Neofetch has been such a mainstay that it never occurred to me to check on its development status. Fastfetch isn't in the Debian repos even for Bookworm, but they've got debs and such for it right there on their page so that's cool, though I'm not particularly fond of installing debs from third parties if I can help it.
@gerowen If Neofetch works for you, there is little reason to switch. Especially if the alternatives are a bit troublesome to install. I am on an Arch based system and had to use the AUR, which directly compiles from source. I can understand if you don't want install from non trusted places. Don't know why fastfetch is still not in official repos, in Arch or Debian, as Neofetch is not worked on anymore.
