Show HN: Remux – an open-source tmux workspace designed for iPhone (github.com)

Hi HN, i'm building Remux, a touch-first tmux workspace for iPhone, powered by Ghostty’s terminal core. It makes sessions, windows, and panes easier to navigate on a small screen, and includes:

- Long-press previews for file paths and localhost links in terminal output

- Saved commands

- File and photo attachments

- Image annotation and touch-friendly terminal controls

Remux is free, open source, and MIT-licensed.

TestFlight: https://testflight.apple.com/join/fHqG1ruE

Demo: https://getremux.app

I think this is a very cool effort. Sorry you got downvoted to oblivion (probably because of the "vibe-coded" feel of the website and website copy, etc.)

I'll try it out!

Question for you — what is your security model? It seems like this only supports local network access, is that correct?

I have been wanting for something like this, today I use a PWA running off Tailscale on my device for simplicity, but a native app would be nice.

The amount of things mitchellh’s ghostty have enabled has been awesome

The app looks great, congratulations on the beta. Will continue testing it, but it connects well and works quite fast. I mainly use Termius, but the tmux support here is interesting.

Any way to see multiple panes at the same time?

I don't know much about the SSH this app uses (Citadel) which uses NIOSSH under the hood. I prefer using Mosh (https://github.com/mobile-shell/mosh) for mobile apps where connectivity is often spotty. Does NIOSSH use a model that accounts for that?

Please support /voice for claude!

congrats on the launch, I can see how much thought and work went into building this.

I have always secretly wanted someone to hack up something like tilda for android, with a shortcut to drop down. The APIs do not exist to support it tho... well, not that I could find. Guessing someone really clever could figure it out.

Neat! I'm curious, did you consider building on top of https://github.com/neurosnap/zmx which also does attach/detach and uses libghostty?

The app looks cool, and the website design (tmux style pane at the bottom) is very clever. Nicely done. Will be giving this a try!

Been using Blink.sh with mosh, and the persistence of session is a joy, but the interface is still.. awkward at times.

super cool, any interest in supporting fwknop/port knocking? happy to put up a PR

Can anybody suggest a good terminal for iOS? I’ve used iSH a fair amount in the past but that hasn’t had an update in three years. I’m mainly just looking for tools like curl, dig, ping etc.

this is awesome. i was just claudding an exact copy of this. thanks for saving my tokens :)

This looks great!

Can I get arrow keys for the keyboard?

This is great – I built almost the same thing. It's eerie how similar it made that footer on the public websites! Your app definitely looks a bit nicer than mine though! https://belfry.robgough.net

I actually started with a Mac app primarily, as I wanted to have an easier way to switch sessions with the mouse and see Claude Code's status at a glance (I had herdr envy, but wanted to keep tmux). I then figured why not do the iOS/iPad version while I was at it.

Highly encourage you to build out a Desktop version, I'm now using mine as my only terminal and wouldn't go back. Working across machines feels seamless.
