What Kiro Costs in 2026 — and How Startups Get Pro+ Free

Updated October 10, 2026. This started as coverage of Amazon’s re:Invent 2025 giveaway. Ten months later the startup offer is still open (in a leaner form), and Kiro’s pricing has settled into a five-tier menu worth understanding before you commit a team to it. The plan table, the credit-limit section and the startup terms below were checked against Kiro’s official pricing and startup pages on July 14, September 20 and October 10, 2026, with no price changes across the three.

How Much Does Kiro Cost in 2026?

Kiro’s per-user plans run from free to $200 a month, and the differences are almost entirely about how many credits you get:

“Premium models” on the paid tiers means access to Auto (Kiro’s model-routing agent) plus frontier models, which Kiro’s pricing page listed as “including Auto, Claude Sonnet 5 and Claude Opus 5” on October 10, 2026, and model choice affects burn rate: Kiro says a task that costs X credits via Auto costs 1.3X via Sonnet 4.6.

Every paid tier can buy add-on credits at $0.04 each when you sign in with a social login or an AWS Builder ID; enterprise sign-in uses overages instead, covered below. The same four paid plans are what a team buys: Kiro’s page marks each one “for teams up to 500” and says teams get consolidated billing, usage analytics, single sign-on through AWS IAM Identity Center, and pay-per-use overage, also $0.04 per credit. One exception to the whole table: “Kiro in GovCloud pricing is approximately 20% higher than commercial pricing and does not include the Free tier.”

One more freebie, bannered at the top of the pricing page: Amazon credits $20 toward your subscription the first time you upgrade to any paid plan using social login or an AWS Builder ID. That is worth one month of Pro, and it is prorated: in Kiro’s own example, upgrading to Pro on June 15 uses $10 of the credit in June and the other $10 against the July 1 charge.

What Is a Kiro Credit Worth?

These are the numbers Amazon doesn’t put on the pricing page. Divide each tier’s price by its bundled credits and every single paid plan lands in the same place:

$\frac{\$20}{1{,}000} = \frac{\$40}{2{,}000} = \frac{\$100}{5{,}000} = \frac{\$200}{10{,}000} = \$0.02 \text{ per credit}$

Bundled credits cost 2 cents on every standard paid tier; add-on and overage credits cost 4 cents, exactly double. The pricing ladder isn’t a volume discount, it’s a commitment scale: you pick a tier by predicting your usage, and the penalty for guessing low is paying 2× on the margin. Moving up a tier only wins once you overshoot by more than half the next tier’s extra credits: past 500 extra credits on Pro, 1,500 on Pro+, or 2,500 on Pro Max, the bigger plan costs less than the add-ons would. Below those lines, add-ons are the cheaper way to cover a busy month. It’s the same subscription squeeze covered in The Cheaper AI Gets, the Bigger Your Bill: per-unit AI prices fall while the packaging pushes your monthly spend up.

What Happens When You Reach Your Kiro Limit?

You stop until the month turns over, you pay 4 cents a credit to keep going, or you upgrade. Which of those is open to you depends on your plan and how you sign in.

When the limit resets. Kiro’s pricing page says “usage limits reset at the start of each billing month,” and “unused credits do not roll over to the next month.”

On a paid plan. Pro, Pro+, Pro Max and Power users who sign in with a social login or an AWS Builder ID can “purchase add-on credits to continue working.” Kiro says those credits “cost $0.04 each, are billed immediately when you buy a pack,” that “packs range from $5 (125 credits) to $100,” and that, unlike plan credits, “unused add-on credits roll over and expire 12 months from the date of purchase.” The smallest pack works out to the same 4 cents: $5 divided by 125 credits.

On the Free tier. The 50 monthly credits are the whole allowance, and Kiro adds that Free-tier model access “is subject to rate limits.” Buying add-on credits is listed only for the paid plans, so on Free the choices are to wait for the reset or upgrade; the first upgrade carries the $20 credit described above.

On an enterprise account (AWS IAM Identity Center sign-in). Overages are off by default. Kiro says admins “can enable overages so users keep working past their limits automatically,” billed “at $0.04 per credit at month-end,” and that “overages are disabled by default and must be enabled in the Kiro console settings.” If a work account stops at the limit, that switch is the first thing to ask your admin about.

How to see it coming. The subscription dashboard inside Kiro shows “the monthly credit limits for your plan, the number of credits used, and credits remaining,” and Kiro says usage there “is updated at least every 5 minutes.” Credits are metered finely, “to the second decimal point,” so small prompts do not each burn a whole credit.

How to Get Kiro for Free

Three legitimate routes, no coupon-site nonsense:

1. The Free tier: $0, 50 credits a month, and notably it includes an Anthropic model alongside open weight models like Qwen3 Coder Next and DeepSeek 3.2, provided you sign up with a social login or AWS Builder ID. The Claude you get on Free is Claude Sonnet 4.5: as of October 10, 2026, both the plan card and the FAQ on Kiro’s pricing page name it. Fifty credits won’t power a team, but it’s enough to evaluate whether Kiro’s spec-driven workflow fits how you build.
2. The $20 first-upgrade credit: sign up with social login or an AWS Builder ID and the credit is worth one month of Pro, spread across your first billing periods.
3. The startup program: the big one, still open, covered next.

Kiro for Startups: Up to a Free Year of Pro+ Is Still Open

The re:Invent 2025 offer’s own deadline passed, but a smaller version replaced it. As of October 10, 2026, Amazon is still taking applications for up to one year’s worth of Kiro Pro+ credits, reviewed on a rolling basis. The offer comes in three sizes:

Eligibility, per Kiro’s startup page:

• Early-stage to Series A startups. The page’s wording is “an early stage to Series A startup”; it does not repeat the venture-funding requirement TechCrunch reported at launch.
• A business email on your startup’s own domain, plus an AWS Account ID registered with a matching email.
• Not in AWS Activate. The page says it two ways: “Startups with active AWS Activate Credits are not eligible for this promotion,” and, in its FAQ, “Startups who have joined AWS Activate are not eligible for this offer.” The exclusion runs one way: startups accepted into the Kiro program “can still apply for AWS Activate afterwards,” and Activate credits can be spent on Kiro.
• A different sign-in from the $20 credit above. “To use your Kiro startup credits, you must log in to Kiro using AWS IAM Identity Center,” and they “are not available when logging in with AWS Builder ID or social logins.” The $20 first-upgrade credit is the reverse: it applies to social login or Builder ID, “not AWS Identity Center,” and “The free tier is not available in Kiro Enterprise.” The three free routes do not stack on one login.

Know what you’re applying to, though: this is a leaner offer than the one that made headlines in December. The launch version, as TechCrunch reported it, took startups with venture funding from pre-seed through Series B, covered up to 100 users, and set an application deadline of December 31, 2025. The version running in October 2026 caps out at Series A and 30 users, takes applications on a rolling basis, and says only “for a limited time,” with no end date named. Set against the launch terms TechCrunch reported, Amazon kept the window open while shrinking what’s behind it, and it could just as easily close it, which is a reason to apply now rather than wait. One more asterisk: the “globally” in the pitch excludes applicants in a long list of places. As of October 10, 2026, the program FAQ excludes people living in Argentina, Brazil, Greater China, France, Germany, Italy, Mexico, Poland, Spain and the United Arab Emirates, along with Russia, Belarus, Iran, Cuba, Syria, North Korea, Crimea and the two regions it calls the so-called Donetsk and Luhansk People’s Republics. The United States is not on that list, and TechCrunch’s launch report said “U.S.-based startups are eligible”; check the startup page if you are elsewhere.

What Is Kiro, and Why Is Amazon Paying You to Use It?

Kiro is Amazon’s AI coding tool. TechCrunch framed the giveaway as Amazon’s attempt to get “past Cursor, Claude Code, Codex, Gemini Code Assist, GitHub Copilot” and the rest of a crowded field. Kiro’s own pitch to startups is specs and security: “Build faster with specs,” “Easily transition from vibe to spec mode,” and “Built on AWS with security and privacy.” For a closer look at how that spec-driven approach works, see The Architecture of Action.

The economics of the giveaway look like a loss leader. A Scale-tier grant is worth at most $14,400 at list price per startup. TechCrunch’s read at launch was that Amazon “wants to try using the tried-and-true method of giving its tool away for free.” If the free credits turn a young team into an AWS shop whose infrastructure, deployment and development workflow all live in Amazon’s ecosystem, the giveaway has done its job. That last step is a reading of the incentives, not something Amazon has said.

Should You Take the Deal?

If you’re an eligible startup that has not joined AWS Activate, applying costs little. Know where it can start costing money: “Once you’ve used up all your credits, you’ll automatically switch to standard Kiro Pro+ billing,” and if you pick a plan above Pro+ or exceed your tier’s user count, “you may be charged additional fees.” The credits also “expire one year after date of issuance,” the clock starts when they are issued (they “will be activated upon provisioning”), and “You may only receive credits once.” Beyond that:

• Already on AWS? Kiro’s team sign-in runs through AWS IAM Identity Center, and startup credits are added to your AWS account, so there is no new vendor to onboard. Whether it beats the tool you use now is something only a trial will tell you.
• IP-sensitive? Kiro’s pitch to teams includes “enterprise security and privacy controls”; have your legal team read the terms before anyone pastes in code.
• Happy with Cursor? Run Kiro on the free tier next to it for a month. The 50 credits are enough to find out whether spec mode changes your mind, and competition means you win either way.
