"I guess I'm asking for a "Convince me to try it" style review of juice" Notice this is about juicessh becoming unusable and no longer having any support. That should satisfy you.

I used JuiceSSH many years ago, had the Pro version when it was briefly free once. I've used Termux for years now and it seems better to me. You can set up ssh keys and aliases like usual, multihop works. I think I used to use Hacker's Keyboard but now I use AnySoftKeyboard since it had better alt layout support (e.g. Dvorak, Workman). I've got a row at the top with ctrl, tab, arrows, esc... It even works to do C-a, C-c, C-v in other apps. I'd recommend the combo. All available from F-Droid.

Yes I use termux too. What I love is that everything works that works on a normal computer too. And the same way. Even ssh keys on yubikeys work great with open keychain and okcagent.

I bought Juice pro many years ago and use it daily on my phone and Tablet. I like how it gives my one click access to my handful of servers, and I liked the syncing between devices. I started using Termux last week and it seems like a decent alternative. The copy and paste is nicer on JuiceSSH, and I think it is more immune from getting disconnected if you switch to another app during a session.

Have you looked into enabling ssh keep alive/server alive?

From what I've read, TCPKeepAlive can be a good or a bad thing. On the one hand, sending a packet every now and then can dissuade a middle box from dropping the connection. On the other hand, if the connection is temporarily not working and would have started working again a few minutes later the attempt to send an unnecessary packet could cause the connection to break permanently when it wouldn't otherwise have broken. I suppose that next time I have a recurring problem I should try both.

Sharing in case this can help you in the future, this is what works for me with Termux in .ssh/config

  ServerAliveInterval 120
  ServerAliveCountMax 30
  TCPKeepAlive yes

I have used neither juice nor termux.

For my few emergencies ConnectBot worked quite well as an ssh client for me, including port forwarding (so i could use VNC sessions to unlock a boot issue in a VM using some VNC app)

I wonder why nobody mentions serverbox

For me it's mostly that it just works and was very easy to set up when I first used it.

It has an SSH focused GUI which can be more convenient

What does that mean.

Buttons

Can I use that keyboard only with termux?

No, it's a generic android keyboard and works with all apps. But you need a keyboard like it (arrow keys, ctrl, etc.) for termux to not be a total PITA to use.

(Android has full physical keyboard support, so with it you can use Ctrl+A/Ctrl+X/Ctrl+V in all input fields. Usually a lot faster than fumbling with the touch equivalents that keep randomly bugging out…)

To add to this you can define custom keyboards quite easily for just about any unicode character you can imagine and more. It is an extremely underrated keyboard. It doesn't come with autocorrect built in though, but i barely notice. The privacy it offers is a nice touch, and its functionality unmatched.
