Keep every host connected, run saved snippets, open forwarded web UIs in an in-app browser, and work in tmux or herdr with tabs and panes that feel native. Checking on your coding agent, or any terminal app, from your phone? Paste it a screenshot, draft a prompt, hit Esc.
Free for one host · $1.99 once for unlimited hosts, no subscription · iOS 26+
A homelab, a cloud VM, a build box. dotMux keeps several hosts connected at the same time: leaving a terminal doesn't disconnect it, so moving between servers is a tap, not a reconnect.
Save the commands you keep retyping, and reach the web UIs that only listen on the server's localhost — no VPN, no port exposed.
dotMux speaks tmux control mode (tmux -CC) and herdr's own protocol, so your remote session isn't drawn as one big terminal: windows become tabs, panes become native views, and every operation runs through the multiplexer itself.
An agent waiting on you needs more than letters: a screenshot of the bug, a long prompt, an Esc to interrupt it. dotMux puts all of it on a phone.
One universal app. On iPhone, each pane gets the full screen. On iPad, panes sit side by side — your agent, its diff and your logs at once — and you resize them by dragging the dividers.
dotMux runs no servers and has no account. It connects straight from your device to your machines, and the developer never receives your keys, passwords or traffic.
Also in dotMux: themes, fonts and Ghostty or iTerm2 theme import · Shortcuts automation · re-attach after iOS suspends the app
No subscription, no account, no trial clock.
One saved host, fully featured: tmux and herdr, every key type, Face ID, iPad multi-window.
Save as many servers as you like. A one-time purchase, with Restore Purchases.
No, but it's where dotMux shines. With tmux or herdr, your windows and panes become native tabs and views and survive iOS suspending the app. Without either, a host opens as a plain SSH terminal. tmux control mode →
Your shells, builds and agents keep running on the server, inside tmux or herdr. When you come back, dotMux re-attaches to the session and rebuilds your tabs and panes where they were. Coming back after iOS suspends the app →
ed25519 and ECDSA (P-256) keys, imported by paste or from Files, or a key generated inside the Secure Enclave that never leaves the chip. Passwords work too. RSA keys aren't supported. Keys and passwords →
Yes, and with any other terminal app. Agents run in tmux or herdr on your server like any other CLI, and dotMux is the terminal you reach them through. Paste an image and dotMux uploads it to the host and types its path — Claude Code attaches it as [Image #1]. Pasting images into Claude Code →
No. dotMux has no servers and no account. It connects straight from your device to your machines, and collects no data. Security and privacy →
Jump hosts (ProxyJump), an SFTP file browser, SOCKS, reverse and agent forwarding, and iCloud key sync are deferred. RSA keys are left out on purpose. Local port forwarding ships. What isn't supported yet →
dotMux doesn't support mosh, on purpose. mosh runs a terminal emulator on the server and sends a picture of the screen, which drops inline images and newer terminal features. tmux and herdr cover dropped connections instead: your work keeps running, and reconnecting re-attaches you to it. Why not mosh →
