For Gopher, I used to use a little terminal browser called Phetch:
https://github.com/xvxx/phetch
It's written in Golang and was last updated in 2022. There's a GIF on the Github page to give a feel of what Phetch & browsing Gopher in the terminal is like. I mostly use the Lagrange GUI client though, which is fantastic.
Gopher still exists. If you're starting out, you can get your own "gopherhole" and Unix shell account at https://sdf.org/ It's a long time since I updated mine, but I'm at gopher://sdf.org:70/1/users/syneryder/
I kinda of remember when Mosaic supported all the protocols. One would just replace http with whatever protocol wanted to connect to the host with.
gopher:// or ftp://
This makes me wonder if someone is putting the latest version of the Factbook on Gopher now. It might be a fun little project?
PS. Lagrange is a beautiful piece of software.
