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
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?

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!

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.

thanks! if you try it, let me know if there are any features you’d like to see.
The amount of things mitchellh’s ghostty have enabled has been awesome
bitwise42•Jul 23, 2026
absolutely. ghostty is one of the projects i admire most, built by the engineer i look up to most.

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?
bitwise42•Jul 23, 2026
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.

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?
bitwise42•Jul 23, 2026
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.

thanks for flagging this. i'll look into it.
tamimio•Jul 23, 2026
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.

Please support /voice for claude!
bitwise42•Jul 23, 2026
thanks for the feedback. i'm working on making voice input more seamless.
rutharuth•Jul 23, 2026
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?
bitwise42•Jul 23, 2026
zmx is neat. i came across it in the ghostty discord. i chose tmux since most people already have their workflow built around it.
oarsinsync•Jul 23, 2026
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.
bitwise42•Jul 23, 2026
thanks, really appreciate that. let me know if anything is missing for your workflow once your try remux
