Control AI agents from your phone

AI agents do their best work when someone is watching: kicking them off, approving the risky steps, and nudging them back on track. QuickTUI puts that control in your pocket: start an agent on your own machine, then supervise and steer it from your phone over a real terminal.

Supervising and steering an agent from the QuickTUI terminal toolbar.

Agents like Claude Code and Codex run in a terminal and work over minutes, so the useful question is not "can I chat with it" but "can I keep it running and keep it honest from anywhere." QuickTUI is a native iPhone and iPad app (plus a browser client) that attaches to real tmux on a machine you host, so the agent stays alive on the machine while you drive it from the phone.

Kick off and supervise

Set up your machine

Install QuickTUI on the machine where your agents should run. It sets up the service. On macOS/Linux install tmux 3.2+ yourself first (the installer does not install tmux). On Windows it installs the qscn session backend automatically.

macOS / Linux

curl -fsSL https://quicktui.ai/q.sh | sh

Windows (PowerShell)

irm https://quicktui.ai/q.ps1 | iex

Windows note: the session backend is qscn, not tmux. Create sessions with New Session in the app; the tmux new-session examples below apply to macOS/Linux.

Pair the app with the platform commands below, or add a server by URL and token.

# macOS / Linux
quicktui-server --pair-qrcode

# Windows (PowerShell)
& "$env:LOCALAPPDATA\QuickTUI\quicktui-server.exe" --pair-qrcode

The connection is direct by default, so your code and keys never touch our servers.

Works with any agent

Because QuickTUI drives real tmux, it is not tied to one tool. Run Claude Code, Codex, or any CLI agent, each in its own session, and switch between them from the phone.

tmux new-session -s agent
claude   # or: codex, or any CLI agent
Several agents at once. Start each agent in its own tmux session and supervise the whole set from one app: one on a feature branch, another running tests, a third tailing logs. A single machine is free with full features; QuickTUI Pro is a one-time purchase for unlimited machine profiles.

FAQ

Which agents can I control?

Any CLI agent that runs in a terminal: Claude Code, Codex, or your own tools. QuickTUI drives real tmux, so it is not limited to a specific product.

Can I approve steps and steer the agent, not just read output?

Yes. You get the live terminal, so you can answer prompts, approve tool calls, and redirect the agent in real time from your phone.

Does the agent keep running while I am away?

Yes. It runs in tmux on your machine and continues after you detach. The session keeper reattaches to the live session across network changes, app restarts, and dropped connections.
