THE VERDICTderived from the rows below, so it cannot say anything the table does not

On the prices each vendor publishes about itself, OpenAI Codex CLI starts at Not read and Zed at Free, then $10 / mo. Both take your own API key, so on either one the subscription and the model bill are separate decisions. Both are open source, so neither can withdraw the thing you have already installed. Every figure on this page was read from the two vendors' own pages in last night's run rather than written down once, which is the only reason it is still the current answer. ToolDrift sells neither and takes no referral fee on either.

THE QUESTIONS3 answered from the rows above

Is OpenAI Codex CLI or Zed cheaper?

On the cheapest option each vendor publishes: OpenAI Codex CLI is Not read and Zed is Free, then $10 / mo. Treat both as an allowance rather than a bill, every tool in this category meters model usage on top of the plan, and which one costs more in practice depends on the models you drive and how hard. The tier prices are the part that can be checked from outside, so they are the part this page prints.

Can I use my own API key with OpenAI Codex CLI or Zed?

OpenAI Codex CLI: yes. Zed: yes. It is the row that decides whether the subscription price is most of what you pay or a fraction of it: a tool that takes your own key charges for the software, and one that does not is reselling inference with a margin you cannot see.

Are OpenAI Codex CLI and Zed still maintained?

Active and Active as of last night's read. OpenAI Codex CLI's repository was last pushed 0 days ago and it scores 100/100 on maintenance; Zed's repository was last pushed 0 days ago and it scores 94/100 on maintenance. This is the question a written comparison cannot answer, because it was true on the day it was published and nobody went back.
