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

On the prices each vendor publishes about itself, Kiro starts at Free, then $20 / mo and Zed at Free, then $10 / mo. Zed takes your own API key; the other bundles model usage, so its headline price is closer to the whole bill. Zed is open source under GPL-3.0; the other is proprietary. 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 Kiro or Zed cheaper?

On the cheapest option each vendor publishes: Kiro is Free, then $20 / mo 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 Kiro or Zed?

Kiro: no, model usage is bundled. 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 Kiro and Zed still maintained?

Active and Active as of last night's read. Kiro publishes no repository this site tracks, so there is no push date to read; 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.
