I use one called X-Plore. It's actually very good. Even has a WiFi server, conpressed archive support, etc. but the downsides are that it's close sourced and some features are behind a paywall (though IMO they are worth it).
So I was thinking of moving to some free or open source software. Any recommendations?
It's free (not sure if FOSS), and there are non-essential-but-nice-to-have features that are paid, just to support the dev - but the free features are awesome, and more than enough for me.
It's not FOSS.
FOSS means Free Open Source Software (Free as in freedom, not as in free beer).
MiXPlorer is neither open source nor licensed under a FOSS license.
It's proprietary.
Same for me, switched from Total Commander, since Material Files is a bit more comfortable to use. For some reason I do not get the same upload speeds to my home server though, and I cannot figure out why.
That said Total Commander sometimes lost connection and I had to start over, so I am ok with slower upload if its more consistent.
I had been using Solid Explorer and decided to try some open-source options. Amaze seems to be the best of them, but I went back to Solid Explorer after trying it for a few weeks.
