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.

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?

Comment by bitwise42 1 day ago

thanks. there isn't a multi-pane view currently. i chose to show one pane at a time because of the available viewport on phones. you can switch between panes using the pane picker in the bottom sheet, but i'll consider adding that if there's enough demand.

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

Comment by bitwise42 1 day ago

zmx is neat. i came across it in the ghostty discord. i chose tmux since most people already have their workflow built around it.

Can I get arrow keys for the keyboard?

Comment by bitwise42 2 hours ago

you can long press the spacebar (or inside the terminal if you don't wanna open the keyboard) and drag in a direction you want for arrow keys

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.

Comment by tambourine_man 1 day ago

What PWA are you currently using?

Comment by hmokiguess 1 day ago

My own fork of this https://github.com/tiann/hapi with Tailscale and less features I don't need

Comment by bitwise42 1 day ago

thanks! if you try it, let me know if there are any features you’d like to see.

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?

Comment by bitwise42 1 day ago

NIOSSH itself doesn't include Mosh support, so adding it would require a mosh client. i didn't include it in the initial beta, because mosh isn't direct fit for tmux control mode, which requires an ordered raw byte stream. i'm planning to add mosh for standalone terminal sessions tho.

>this app isn’t available in your country

Comment by bitwise42 1 day ago

thanks for flagging this. i'll look into it.

Comment by tamimio 1 day ago

No, your app (remux) is installed and works well. I was replying to GP Mosh/Blink app which is on iOS too, but it isn’t available to download.

Comment by oarsinsync 1 day ago

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.

Comment by bitwise42 1 day ago

thanks, really appreciate that. let me know if anything is missing for your workflow once your try remux

Comment by jambalaya8 1 day ago

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.

Comment by cpressland 1 day ago

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.

Comment by drudoo 1 day ago

I switched to Termix some months ago and I’m very happy with that.

Comment by bitwise42 1 day ago

i think Blink Shell seems a good fit for your usecase.

This looks great!

Comment by gigatexal 1 day ago

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

Comment by bitwise42 1 day ago

absolutely. ghostty is one of the projects i admire most, built by the engineer i look up to most.

Comment by sdzgs 1 day ago

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

Comment by sebmellen 1 day ago

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?

Comment by bitwise42 1 day ago

thanks for giving it a try. it isn't limited to local networks. Remux connects directly over ssh to any machine reachable from the iPhone, including thru a private network such as tailscale.

Thank you for making it! Let me sponsor you on GitHub!

We are hiring smart + driven engineers (email in bio).

Please support /voice for claude!

Comment by bitwise42 1 day ago

thanks for the feedback. i'm working on making voice input more seamless.

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

Comment by rutharuth 1 day ago

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

Comment by bitwise42 1 day ago

thanks, i really appreciate that.

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.
