AI product Open source
OpenAI Codex is an AI coding agent offered as a local command-line tool, IDE integration, desktop app, and cloud-based agent. The Codex CLI runs locally on a computer and can be installed on macOS, Linux, or Windows; the repository also directs users to integrations for VS Code, Cursor, and Windsurf, and to the Codex app and Codex Web.
The videos describe Codex as an agent for building applications, websites, automations, and long-running software projects. Its workflows can use supplied context such as Slack conversations, repository history, images, memory, plugins, and skills; drive browsers and desktop applications through computer use; and coordinate work with goals, subagents, threads, hooks, audits, and automations. The videos also describe Codex App Server as an open-source protocol for embedding Codex in other products.
The repository provides installation through shell or PowerShell installers, npm, Homebrew, or downloadable releases. Users can sign in with a ChatGPT plan or configure an API key. The repository is licensed under Apache-2.0.
