Choose OpenAI Codex if
you want an open-source CLI (Apache 2.0) plus IDE extensions (VS Code, Cursor, Windsurf, JetBrains, Xcode), cloud tasks and the ChatGPT desktop app, all on your ChatGPT account. A $0 Free plan includes Codex in the desktop app, subject to rollout. The Codex extension also runs inside Cursor.
Choose Cursor if
you want the agent built into a dedicated editor, with a CLI (headless and GitHub Actions support) and, from Premium, cloud agents from the same vendor, and a choice of models from Anthropic, OpenAI, Gemini, Cursor and Grok. Cursor isn't open source, its Plus plan is Grok-models-only, and third-party models cost extra at API list price from Premium up.
