Weaknesses

Claude Code

No free plan, and usage is shared.¹Why it matters: Claude Code needs a paid Claude plan (from $17/mo billed annually), and coding draws on the same 5-hour and weekly limits as your chats.
Builders say the limits run out fast.⁵³Why it matters: One builder on the $20 plan hit the 5-hour limit in under 2.5 hours; heavy users plan around the cap or move up to Max ($100/mo) or Ultra ($200/mo).
Can need more iterations and supervision.³⁶Why it matters: Builders say its code often takes extra rounds to get right and that it needs a focused driver, so budget review time.

Codex

Free and Go access is limited.²Why it matters: On ChatGPT Free and Go ($8/mo) Codex runs GPT-6 Luna in the desktop app, subject to rollout. The web, CLI, IDE extension and cloud code review start at Plus ($20/mo).
Slower and less interactive.⁶⁴Why it matters: Builders call it noticeably slower on the same task, and say it can make assumptions about a codebase without reading everything first.
Can over-engineer when left alone.³Why it matters: Builders say it works best with a clear plan; without one it can get stuck or add complexity.

Final verdict

Choose Claude Code if

You want an agent you steer as it works, you do a lot of multi-file refactors, reviews or planning, or you already pay for Claude.

Choose Codex if

You’re on a budget or want to start free, you keep hitting usage limits, or you already pay for ChatGPT and want to hand off focused tasks.

Overall takeaway: No overall winner from our sources. Codex is the cheaper start and builders find its limits more generous; Claude Code is the one builders prefer for interactive, complex work. Many run both, for example Claude Code to build and Codex to review. Neither is hands-on tested by us.³⁴⁵
