Pros & Cons from Real Users

Pros

  • Codex CLI is great because it brings OpenAI’s coding agent directly into the terminal. I like that it fits into a normal developer workflow instead of forcing everything through a separate web app or IDE extension. It can read, modify, and work with code locally, which makes it useful for debugging, refactoring, exploring a repo, and handling coding tasks without leaving the command line. That is especially nice for developers who already live in terminal-first workflows. I also like that it is part of the broader Codex ecosystem. If I want the same general agent experience in an IDE, desktop app, or ChatGPT’s cloud-based Codex, there are options for that too.

Cons

  • I would still supervise it closely. Any AI coding agent that can touch local files and interact with a dev environment needs review, tests, and clear boundaries. It can also run into the usual coding-agent issues: setup problems, API/config errors, terminal quirks, command failures, and tool-use mistakes. A recent empirical study of Claude Code, Codex, and Gemini CLI found that many reported bugs in these tools involve functionality, integrations, configuration, terminal behavior, and command execution.
