Phone control for AI coding sessions is not a tiny terminal

Most mobile AI coding workflows eventually hit the same wall.

tmux keeps the process alive. SSH lets the phone attach. Remote desktop can show the whole screen. None of that means the phone is a good control surface.

On a phone, the common loop is much smaller:

see which Codex, Claude Code, or shell session is alive
read the last meaningful output without parsing a full terminal wall
send a short nudge back into the same running process
approve or reject a blocked action
interrupt when the agent is clearly going wrong
hand the context back to the desktop without creating a second history

That is the gap I built Faryo for.

Faryo is an open-source phone/browser workbench for tmux-backed AI coding sessions. The local tmux session stays the source of truth. Codex CLI, Claude Code, or a plain shell keeps running on the host. The phone/browser layer is deliberately thin: compact output, short input, approve/interrupt, and handoff.

It is not a remote desktop. It is not a cloud IDE. It is not another AI chat thread.

The narrow promise is: keep the same live terminal session, but stop forcing the phone to behave like a full terminal.

I kept seeing the same mobile AI-coding problem: SSH + tmux keeps the process alive, but the phone is still a tiny terminal.

Faryo is my narrow answer to that.

It keeps Codex CLI, Claude Code, or a normal shell inside the host tmux session. The phone or desktop browser is only a control surface:

read compact output
send a short steer
approve or interrupt
attach a handoff note, screenshot, or file
return to the same live session later

It is not a remote desktop, not a cloud IDE, and not a second chat history.

The current most-tested path is Linux + tmux + Codex CLI / Claude Code + Android Chrome PWA. The repo is here:

I am mainly looking for people who already tried phone SSH, Termius, Tailscale, Claude Remote Control, or Codex Mobile and hit the "same session, but readable and controllable from the phone" problem.
