How it works

  1. Install

    Run the installer or the portable exe. Sign in once to each agent CLI you use, in any terminal.

  2. Add projects

    Pick a folder and a default agent. A short first-run setup shows which CLIs it found.

  3. Start sessions

    Press Ctrl+N, or run paneon . in a folder. Each agent runs in its own pane.

  4. Stay on top

    Glance at status, plans and context. Come back when a pane asks for you.

The paneon command

The installer adds it to your PATH. Open a new terminal and drive Paneon from where you already work.

# add this folder and start its agent
paneon .

# start a specific agent on a project
paneon start billing-api --agent codex

# pick up the newest session
paneon resume --last
