codex is an open-source dev tools project by openai (openai/codex on GitHub). It has 128,197 GitHub stars and 20,112 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 8 October 2026.
Decide what you want from codex and check the README and requirements to confirm it fits your setup and Rust environment.
Clone the repository from GitHub (github.com/openai/codex) or use the documented install channel if you do not need the source.
Follow the README quickstart to install dependencies and set any required configuration or credentials.
Work through the README's first example end to end, then adapt it to your own project or data.
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
Also available inside VS Code, Cursor and Windsurf through the IDE integration.
Run `codex app` for the desktop app experience, separate from the cloud Codex Web.
Sign in with your ChatGPT Plus, Pro, Business, Edu or Enterprise plan, or use an API key.
Install via the standalone installer script, npm (`@openai/codex`), or Homebrew.
GitHub Releases ship per-platform binaries for macOS and Linux on arm64 and x86_64.
Start by getting the source and entering the project directory.
git clone https://github.com/openai/codex.git
cd codexUse OpenAI's installer script on Mac or Linux, or `npm install -g @openai/codex`.
curl -fsSL https://chatgpt.com/codex/install.sh | shStart it and sign in with your ChatGPT plan when prompted.
codexIt is maintained by openai and contributors on GitHub, where the repository github.com/openai/codex is the canonical home for code, issues and releases.
Yes — it is open source under the Apache-2.0 license. Read the license in the repository for what is permitted, including any conditions on redistribution or commercial use.
You need either a ChatGPT plan sign-in or an OpenAI API key — usage is not free beyond your plan or API billing.
Compared with Claude Code: Both are terminal coding agents; Codex ties into ChatGPT plans and OpenAI models, while Claude Code uses Anthropic's Claude models.
Clone github.com/openai/codex, follow the README quickstart to install it, and run the documented first example before adapting it to your own work.
