## Why `remote_control` can appear in `config.toml`, CLI feature overrides, and the app-server config APIs. Before this PR, app-server startup treated `config.features.enabled(Feature::RemoteControl)` as the signal to start remote control ([base code](https://github.com/openai/codex/blob/5e3ee5eddfa5333f2e0b011880abf0cbf92bd295/codex-rs/app-server/src/lib.rs#L678-L680)). That meant a user with: ```toml [features] remote_control = true ``` would accidentally opt every app-server process into remote control. Remote-control startup should instead be a per-process launch decision made by CLI flags. ## What Changed - Marks `Feature::RemoteControl` as `Stage::Removed`, keeping `remote_control` as a known compatibility key while making it config-inert. - Adds a hidden `--remote-control` process flag to `codex app-server` and standalone `codex-app-server`. - Plumbs that flag through `AppServerRuntimeOptions.remote_control_enabled` and makes app-server startup use only that runtime option to decide whether to start remote control. - Removes the app-server config mutation hook that reloaded config and toggled remote control at runtime. - Updates managed daemon spawning to use `codex app-server --remote-control --listen unix://` instead of `--enable remote_control`. Config APIs can still list, read, write, and set `remote_control`; those operations just no longer affect remote-control process enrollment.
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.
