NeoFetch hasn’t had a commit since 2022, and a release hasn’t been made since 2020. I guess the writing was on the wall.
There’s several nice alternatives, but I usually just use fastfetch.
I imagine it was archived by the maintainer who has archived all of his Github Repositories except for one named after his user account which states "Have taken up farming". So presumably he's decided to leave behind the tech projects he's worked on and focus on farming.
