Cursor gives you instant AI editing right in your code editor — you see changes as they happen. Codex works asynchronously, tackling tasks in the background while you do other work.
Cursor is better for real-time editing; Codex for delegating tasks.

A VS Code-based code editor with deep AI integration. Chat with AI about your codebase and it edits files directly. Understands your entire project context.
Ideal for: Developers who already have a project and want AI help editing, refactoring, and extending their code.
By OpenAI
OpenAI's cloud-based coding agent. Assign tasks and Codex writes, tests, and commits code in the background. Works through ChatGPT with a sandboxed environment.
