Is Codex (OpenAI) Worth the Price?
Value Score: 8/10
Overall Score: 8.3/10 · Developers already paying for ChatGPT Plus who want a coding agent at no extra cost. Especially good for parallel task execution -- assign multiple bug fixes or feature branches and let Codex work them simultaneously.
Codex is OpenAI's answer to Claude Code and Devin, and it has one killer advantage: it's bundled with ChatGPT Plus. If you're already paying $20/mo for ChatGPT, you get a cloud coding agent for free. The parallel task execution is genuinely unique -- no other coding agent lets you fire off 5 tasks and check back later. But the rough edges are real: you can't steer it mid-task, complex refactors fall flat, and the usage limits feel tight. For straightforward coding tasks and code review, it's excellent. For anything nuanced, Claude Code's interactive approach is still better.
