Anything that is not using ncurses or terminfo libraries, you can try

$ ldd /path/to/executable | grep 'ncurses\|terminfo'

(with usual cautions related to ldd.)

Basically, anything that uses some other toolkit than ncurses, like Python's
prompt-toolkit, notcurses, Haskell's vty/brick, many programs written in
Rust/Go.
