I'm not sure this is the right community.
I've been hoping for a TUI frontend for Lemmy for a while, but unfortunately none came out and I've decided to build a proof of concept on my own.
It's written in python with pythorhead, blessed and chafa.py and it's quite janky.
While complex tuis are definitely not my cup of tea (I prefer cli tools to be simple, otherwise I would probably use a proper gui), I'm really happy that I'm not the only one wishing for a way to access lemmy from the terminal.
