SSH NoPorts desktop is our original UI for NoPorts, which predates NoPorts' support for using NoPorts over any TCP tunnel. NoPorts originally only supported SSH in its earlier releases.
We don't recommend using this application anymore. It is no longer maintained. The choice to use this application is at your own risk.
If you want a good UI experience, we recommend NoPorts desktop (a.k.a. the npt_flutter directory).
If you want a better SSH experience, we recommend this guide.
