Codex is OpenAI’s coding agent for writing, fixing, reviewing, and shipping code. It connects to a ChatGPT account and supports multiple entry points, from local development to cloud-based repository work.
This section organizes Codex by two questions: which development entry point to choose and how to manage Codex in an organization. ChatGPT plans and core ChatGPT features live in ChatGPT Features & Product Lineup. OpenAI’s Codex manual checked on June 27, 2026 describes Codex App, Codex CLI, Codex IDE extension, and Codex web as the main entry points.[1]
Main Entry Points
| Entry point | Primary use |
|---|---|
| Codex App | Manage threads, worktrees, automations, and local or cloud coding work from the desktop app |
| Codex CLI | Read a local working tree, edit files, run commands, and verify changes from the terminal[2] |
| Codex IDE extension | Work near the code in an IDE and delegate tasks to Codex Cloud when needed |
| Codex web | Connect to GitHub repositories and work in a cloud environment for implementation, review, and pull requests[3] |
