There's https://3code.capocasa.dev/ which is written in Nim and focuses on token efficiency.
my main issues with maki are that the line editor (what you use to enter your prompts) is very barebones, copy-paste is broken (no middle-click paste, or copy to PRIMARY; implicit copying to CLIPBOARD that can only be used with a mouse), and scrollback is not native. So it's not a real cli, but some sort of weblike tui.
I tried 3code; it does not mess with selection, but code printed in the conversation has | markers in every line, and is thus uncopyable in practice. Don't know how to use that.
