## Why The app-server no longer needs to expose a TCP websocket listener. Keeping that transport also kept around a separate listener/auth surface that is unnecessary now that local clients can use stdio or the Unix-domain control socket, while remote connectivity is handled by `remote_control`. ## What Changed - Removed `ws://IP:PORT` parsing and the `AppServerTransport::WebSocket` startup path. - Deleted the app-server websocket listener auth module and removed related CLI flags/dependencies. - Kept websocket framing only where it is still needed: over the Unix-domain control socket and in the outbound `remote_control` connection. - Updated app-server CLI/help text and `app-server/README.md` to document only `stdio://`, `unix://`, `unix://PATH`, and `off` for local transports. - Converted affected app-server integration coverage from TCP websocket listeners to UDS-backed websocket connections, and added a parse test that rejects `ws://` listen URLs. - Removed the now-unused workspace `constant_time_eq` dependency and refreshed `Cargo.lock` after `cargo shear` caught the drift. - Moved test app-server UDS socket paths to short Unix temp paths so macOS Bazel test sandboxes do not exceed Unix socket path limits. ## Verification - Added/updated tests around UDS websocket transport behavior and `ws://` listen URL rejection. - `cargo shear` - `cargo metadata --no-deps --format-version 1` - `cargo test -p codex-app-server unix_socket_transport` - `cargo test -p codex-app-server unix_socket_disconnect` - `just fix -p codex-app-server` - `git diff --check` Local full Rust test execution was blocked before compilation by an external fetch failure for the pinned `nornagon/crossterm` git dependency. `just bazel-lock-update` and `just bazel-lock-check` were retried after the manifest cleanup but remain blocked by external BuildBuddy/V8 fetch timeouts.
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.
