Can I use OpenAI Codex and Cursor together?
Yes — there is no technical or licensing reason you cannot use OpenAI Codex and Cursor side by side. Many people do exactly this: OpenAI Codex for OpenAI's autonomous cloud-based coding agent, Cursor for AI-first code editing inside a forked VS Code. The only cost is paying for two subscriptions if you upgrade both.
What does OpenAI Codex do that Cursor cannot?
