In-Depth Comparison

OpenAI Codex CLI Overview

Codex CLI is OpenAI's open-source coding agent for the terminal. It edits files, runs commands in a sandbox with configurable approval modes, and can hand longer tasks off to Codex cloud to run in the background; the same agent also ships as an IDE extension and a desktop app. Usage is included with every ChatGPT plan, from Free and Go up to Plus and the $100 to $500 Pro tiers, with tighter limits on the cheaper plans, which makes it the default choice for developers already in the OpenAI ecosystem.

Cursor Overview

Cursor is a fork of VS Code redesigned from the ground up for AI-powered development. It features tab completions, natural language code editing, codebase-wide chat, and multi-file editing. Its deep editor integration makes it one of the most polished AI coding tools available.
