This add a new crate, `codex-network-proxy`, a local network proxy service used by Codex to enforce fine-grained network policy (domain allow/deny) and to surface blocked network events for interactive approvals. - New crate: `codex-rs/network-proxy/` (`codex-network-proxy` binary + library) - Core capabilities: - HTTP proxy support (including CONNECT tunneling) - SOCKS5 proxy support (in the later PR) - policy evaluation (allowed/denied domain lists; denylist wins; wildcard support) - small admin API for polling/reload/mode changes - optional MITM support for HTTPS CONNECT to enforce “limited mode” method restrictions (later PR) Will follow up integration with codex in subsequent PRs. ## Testing - `cd codex-rs && cargo build -p codex-network-proxy` - `cd codex-rs && cargo run -p codex-network-proxy -- proxy`
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 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.
