Use Codex in Kettu

OpenAI’s coding agent: it reads code, edits files and runs commands. Your installed, signed-in Codex runs in Kettu as it is: several sessions side by side, approval requests you spot at a glance, your account and settings unchanged.

Three steps

Install, sign in, start a session

  1. 01

    Install

    Install Codex first; if you have not, Kettu shows the official ways to install it in Settings and runs one only when you click it. Kettu runs your codex through codex app-server and installs nothing itself.

  2. 02

    Sign in

    Run codex login in a terminal and sign in with your ChatGPT account or an API key. The sign-in stays in its own config folder.

  3. 03

    Start a session

    Pick a project and Codex, and write what to do; several sessions can run side by side, each in its own worktree.
