## Why Desktop and mobile Codex clients need a machine-readable way to bootstrap and manage `codex app-server` on remote machines reached over SSH. The same flow is also useful for bringing up app-server with `remote_control` enabled on a fresh developer machine and keeping that managed install current without requiring a human session. ## What changed - add the new experimental `codex-app-server-daemon` crate and wire it into `codex app-server daemon` lifecycle commands: `start`, `restart`, `stop`, `version`, and `bootstrap` - add explicit `enable-remote-control` and `disable-remote-control` commands that persist the launch setting and restart a running managed daemon so the change takes effect immediately - emit JSON success responses for daemon commands so remote callers can consume them directly - support a Unix-only pidfile-backed detached backend for lifecycle management - assume the standalone `install.sh` layout for daemon-managed binaries and always launch `CODEX_HOME/packages/standalone/current/codex` - add bootstrap support for the standalone managed install plus a detached hourly updater loop - harden lifecycle management around concurrent operations, pidfile ownership, stale state cleanup, updater ownership, managed-binary preflight, Unix-only rejection, forced shutdown after the graceful window, and updater process-group tracking/cleanup - document the experimental Unix-only support boundary plus the standalone bootstrap/update flow in `codex-rs/app-server-daemon/README.md` ## Verification - `cargo test -p codex-app-server-daemon -p codex-cli` - live pid validation on `cb4`: `bootstrap --remote-control`, `restart`, `version`, `stop` ## Follow-up - Add updater self-refresh so the long-lived `pid-update-loop` can replace its own executable image after installing a newer managed Codex binary.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
