I didn't really get what "a command-line Web, Gemini, and Gopher browser that allows you to work offline" meant, like how is it offline? So I think this is the bit of info I was missing:

Every content you visit is cached and can be visited later while offline. If you try to visit a content not available in your cache, it will be marked to be downloaded later. Offpunk allows you to synchronise you computer once every hour, day or week and work offline without being interrupted.

(from: https://offpunk.net/whatisoffpunk.html)

So its kindof designed to be offline with occasional sync. Interesting.
