Free, or $20/mo to start
OpenAI Codex is for developers who already pay for ChatGPT and want the coding agent in that allowance, web apps and automations with local and cloud tasks, and a few focused coding sessions a week on Plus. The cheapest paid plan the ranking counts is Plus at $20/mo.
A coding agent included with ChatGPT, not a separate app subscription.
Codex is the coding agent in the ChatGPT apps and CLI. You do not buy it on its own. Free and Go include a limited trial. Plus is the first plan with expanded Codex. Pro tiers are for longer daily sessions, and credits extend eligible use after the included allowance.
Individual plans marked for budget matching can change the quiz. Team plans are listed so you can see them, and they do not decide a beginner's rank. Verify means confirm the live page before you quote or pay.

Confirmed on the Codex pricing page as a limited trial. GPT-6 Luna on Free is listed as subject to rollout, so it is not treated as a guarantee.

OpenAI Codex is for developers who already pay for ChatGPT and want the coding agent in that allowance, web apps and automations with local and cloud tasks, and a few focused coding sessions a week on Plus. It is not great for a visual no-code builder for sites and SaaS, staying on the free plan for real project work, and native mobile shipping or game production.
