Is Kiro Free? (2026) Kiro Free Tier, Limits and Who Can Use It
Is Kiro free? What the free tier includes, whether you can use it for personal or commercial work, student access, and when Pro is worth paying for.

Kiro’s FAQ, license and free-tier model note checked Oct 26, 2026 on kiro.dev/faq, kiro.dev/license and kiro.dev/pricing; plan prices checked Oct 22, 2026; student offer checked Oct 22, 2026 on kiro.dev/students; credit costs checked Oct 20, 2026. Every source is listed at the bottom. No affiliate links on this page (how we work).
Short answer: yes, Kiro is free, with 50 credits a month and no published personal-only rule. Kiro calls it the “perpetual Kiro Free tier, which includes 50 credits”. It includes Claude Sonnet 4.5 and open-weight models, “with limits” (Kiro FAQ, checked Oct 26, 2026). It is not unlimited. When the 50 credits are gone, Free users wait for next month. Add-on credits are for paid plans only.
Personal or commercial use: none of Kiro’s pricing, FAQ or license pages limit the free tier to personal or non-commercial use. Kiro is licensed under the AWS Customer Agreement on every plan, so that’s the document to read if your work is commercial. Two things do change between Free and paid, though: Kiro may use Free-tier content for service improvement (you can opt out), and the output indemnity is for paid subscribers only. More on both below.
Students: eligible students at select universities get 1,000 credits a month free for a year. That’s Pro’s credit count, at $0.
We haven’t tested Kiro. Everything below comes from Kiro’s own pages.
Kiro plans and credits
USD per user per month, from kiro.dev/pricing, checked Oct 22, 2026 and seen unchanged on Oct 26, 2026. Prices exclude tax.
| Plan | Price | Credits |
|---|---|---|
| Free | $0 | 50 |
| Students | $0 for 1 year | 1,000 |
| Pro | $20 | 1,000 |
| Pro+ | $40 | 2,000 |
| Pro Max | $100 | 5,000 |
| Power | $200 | 10,000 |
Paid plans can buy add-on credits at $0.04 each, in packs “from $5 (125 credits) to $100”. First-time upgraders who sign in with a social login or AWS Builder ID get “$20 credited toward your subscription”. No yearly price is published. The student row comes from kiro.dev/students (Oct 22, 2026). The full paid-plan breakdown is in Kiro pricing.
What the free tier includes
From Kiro’s pricing page and FAQ, checked Oct 26, 2026:
- 50 credits. Usage limits “reset at the start of each billing month”, and “Unused credits do not roll over to the next month.”
- Models: “Users on the Free Tier who signed up with social logins or AWS Builder ID have access to Claude Sonnet 4.5 and open weight models such as Qwen3 Coder Next, DeepSeek 3.2, and MiniMax M2.1. Access is subject to rate limits.” Premium models like Claude Sonnet 5 and Claude Opus 5 are paid-plan only.
- IDE and CLI. Kiro’s FAQ says you can download the installer, “or sign in to use it with a paid account on the web or mobile”. So Kiro Web and mobile are for paid accounts, and Free means the desktop app and CLI.
- No AWS account needed. “You do not need an AWS account to use Kiro.” You can sign in with GitHub, Google, AWS Builder ID or AWS IAM Identity Center.
- Usage tracking. Your dashboard shows credits used and left, “updated at least every 5 minutes”.
What Free doesn’t get: add-on credits, Kiro Enterprise, and AWS GovCloud. The FAQ says “The free tier is not available in Kiro Enterprise or AWS GovCloud (US) Regions.”
How far 50 credits go
Kiro doesn’t price per prompt. “Simple prompts can consume less than 1 credit. More complex prompts, such as executing a spec task, typically cost more than 1 credit.” Credits are “metered to the second decimal point” (Kiro pricing, checked Oct 20, 2026).
The model you pick changes the cost a lot. Kiro’s models docs (checked Oct 20, 2026) list these multipliers on Free, relative to Auto at 1.0x:
| Model | Multiplier |
|---|---|
| Auto | 1.0x |
| Claude Sonnet 4.5 | 1.3x |
| GLM-5 | 0.5x |
| DeepSeek 3.2 | 0.25x |
| MiniMax M2.1 | 0.15x |
| Qwen3 Coder Next | 0.05x |
Kiro’s own example: a task that costs 10 credits on Auto costs “0.5 credits on Qwen3 Coder Next”. Model selection is “only available for chat experience”, though, so spec tasks don’t get the cheap pick.
Kiro doesn’t publish a fixed credits-per-spec number, so nobody can honestly promise “50 credits = X features”. The practical read: 50 credits on Sonnet 4.5 is a trial. 50 credits spent on chat with Qwen3 Coder Next goes much further, at 0.05x.
Can you use Kiro free for personal or commercial work?
Here’s what Kiro’s pages say, and what they don’t.
No personal-only rule is published. We found no line on kiro.dev/pricing, kiro.dev/faq or kiro.dev/license that restricts Free to personal or non-commercial use (checked Oct 26, 2026).
The license is AWS’s. “The Kiro IDE and Kiro CLI are each licensed to you as “AWS Content” under the AWS Customer Agreement or other written agreement with us governing your use of AWS services, and the AWS Intellectual Property License” (kiro.dev/license, checked Oct 26, 2026). That’s the same document on every plan. If you’re using Kiro for client work, read it. This page isn’t legal advice.
Two real differences for commercial work:
- Your content and training. “We may use certain content from Kiro Free Tier and Kiro subscribers that access Kiro through a social login provider or AWS Builder ID for service improvement. You can opt out of content collection at any time” (Kiro FAQ, checked Oct 26, 2026). Paid users who sign in through AWS IAM Identity Center or an external identity provider are excluded. Working on a client’s private code on Free? Turn on the opt-out first.
- Indemnity. “We provide an output indemnity for paid Kiro subscribers”, subject to Kiro’s excluded models and Section 50.10 of the AWS Service Terms. Free isn’t covered.
So for side projects, Free is fine. For paid client work, Free still works on paper, but the missing indemnity is a reason to pay. Note that paid users on social login or Builder ID are in the same content-use bucket as Free; only paid sign-ins through IAM Identity Center or an external identity provider are excluded.
Is Kiro free for students?
Yes, at select universities. “Eligible university students get 1,000 credits per month free for one year.” “No credit card required” (kiro.dev/students, checked Oct 22, 2026).
The rules, from the same page:
- Only “select universities”, with an account tied to “your university-affiliated email address (e.g., .edu, .ca)”. The school list is on the page.
- You must be at least 18. Verification runs through SheerID, sometimes with a student ID or enrollment letter.
- “Credits do not roll over month to month, and add-on credits are not available.”
- After a year you’re “automatically downgraded to the Kiro free tier.”
Is Kiro free and unlimited?
No. Free is capped at 50 credits a month, models are “subject to rate limits”, and Free users can’t buy add-on credits. Kiro doesn’t publish the exact rate limits on the pages we read. Even paid plans have caps: credits reset monthly and don’t roll over, and only add-on packs carry over (they “expire 12 months from the date of purchase”).
“With limits” and “subject to rate limits” with no numbers is a frustrating way to describe a free tier. Kiro publishes a per-model multiplier table to two decimal places, then goes vague on the one limit free users hit first. Publish the rate limits.
When Pro is worth it
Pro is $20 a month for 1,000 credits, 20 times Free. It adds premium models, add-on credits, Kiro Web and mobile, and the output indemnity. If you sign up through social login or Builder ID, your first upgrade comes with a $20 credit, prorated by days left in the month. Kiro bills paid plans on the 1st of each month.
Pay when either of these happens twice: you run out of 50 credits before mid-month, or you need a premium model for real work. If you’re a student at a listed university, apply for the student offer first. It’s Pro’s credits for free.

Here’s what I’d do
Start on Free with the cheap models in chat. Qwen3 Coder Next at 0.05x stretches 50 credits furthest.
Save credits for one spec. Spec tasks “typically cost more than 1 credit”, so try spec mode on one real feature, not five toys.
Turn on the content opt-out if the code isn’t yours to share.
Students: check the list, then verify. 1,000 credits a month is Pro’s allowance at $0.
Upgrade to Pro for client work. Indemnity and premium models are the real reasons, not just more credits.
