I did not look for alternatives, but in some of the good old linux resources sometimes super new and fancy file managers come up and I took notes on these, because I always planned to develop my own file manager with terminal UI... Especially vim shortcuts are often a thing - I personally like single file binaries that are portable, have sane defaults and easy to setup without root permissions (like lf).
