kiro pricing: every plan, what a credit actually buys, and the catches
updated · prices checked on vendor pages
quick answer: Kiro has a free tier with 50 credits a month, then four paid plans: Pro, Pro+, Pro Max and Power, at $20, $40, $100 and $200 per user a month. every paid plan works out at exactly 2 cents a credit. run out and you can buy add-on credits at $0.04 each, which is double the plan rate. first time you upgrade, Kiro knocks $20 off (pro-rated, more on that below).
we rank Kiro #9 in coding agents (7.0/10). it's the spec-first one: write the plan down, then let it build. good for people who like a list. less good for people who like to wing it at closing time.

the bit worth knowing: bigger plans aren't cheaper per credit
with most tools you pay more to save more. not here. do the sums on Kiro's own numbers and every paid tier lands on the same 2 cents a credit: $20 for 1,000, $40 for 2,000, $100 for 5,000, $200 for 10,000. no bulk discount for going large.
what the bigger plans do save you from is add-on credits, which cost $0.04 each. so if you're on Pro and regularly buying another 1,000 credits on top, that's $40 of add-ons on a $20 plan. Pro+ would have given you the same 2,000 credits for $40 total, without the faff. rule of thumb: if you're topping up most months, move up a plan instead.
what a credit buys
Kiro is honest that it depends:
- a credit is a unit of work in response to a prompt. simple prompts can use less than 1 credit; bigger jobs, such as running a spec task, usually cost more than 1.
- usage is metered to two decimal places, so the smallest job costs 0.01 credits.
- the model matters. by default your prompts go to Kiro's auto agent, which mixes frontier models with smaller specialist ones. pick a specific model and the price changes: Kiro's own example is that a task costing X credits in auto costs 1.3x in Claude Sonnet 4.6.
- vibe mode, spec mode, spec refinement, task execution and agent hooks all spend credits. Kiro powers don't cost anything extra.
paid plans can also pick specific models, including OpenAI's GPT-5.6 (Sol, Terra and Luna), Anthropic's Claude models (Opus 5, Opus 4.8, Sonnet 5, Sonnet 4.6, Sonnet 4.5 and Haiku 4.5) and open weight models such as DeepSeek 3.2, MiniMax M2.5, GLM-5 and Qwen3 coder next. the current credit multipliers live on Kiro's models page, and we haven't measured them ourselves, so we're not going to guess how many "tasks" 1,000 credits is. anyone who tells you a firm number is making it up.
is Kiro free?
yes, properly. the free tier is perpetual, not a trial, and gives you 50 credits. it runs on Claude Sonnet 4.5 and open weight models such as Qwen3 coder next, DeepSeek 3.2 and MiniMax M2.1, with rate limits, and only if you sign up with a social login or AWS builder ID.
50 credits is enough to kick the tyres on a small project and see whether the spec-first way of working suits you. it isn't enough to live in. there's no free tier on Kiro Enterprise or in AWS GovCloud.
the $20 sign-up credit, explained
the first time you upgrade to any paid plan (using social login or AWS builder ID, not AWS identity center), Kiro credits $20 towards your subscription. because billing runs on the 1st of the month, it's pro-rated. Kiro's own example: upgrade to Pro on 15 june and you get $10 credited for the rest of june, then on 1 july your card is charged $20 minus the remaining credit, which is $10. you need a valid credit card to upgrade.
add-on credits
- on Pro, Pro+, Pro Max and Power (social login or builder ID), you can buy add-on credits at $0.04 each.
- packs run from $5 (125 credits) up to $100, and you're billed straight away.
- unused add-on credits roll over and expire 12 months after you bought them.
- your monthly plan credits don't roll over. they reset at the start of each billing month. use them or lose them.
- on Kiro Enterprise, admins can switch on overages at $0.04 a credit, billed at month end. they're off by default.
the catches
1. one subscription per person. you can't share a plan. every developer on a team needs their own.
2. stick to Kiro's own tools. your subscription works in the Kiro IDE, Kiro CLI, Kiro web, Kiro crew, ACP-compatible IDEs and automation such as reviews in CI/CD. using it through third-party harnesses that route requests outside Kiro, OpenClaw being the example Kiro names, isn't allowed.
3. models vary by country. Kiro says not all premium models are available in every country or region.
4. GovCloud costs more. in AWS GovCloud (US) regions pricing is about 20% higher and there's no free tier.
5. Kiro web is paid only. it uses the same credits as the IDE and CLI, with no extra charge for cloud compute, but it's on Pro and up.
which plan should you pick?
- trying spec-first coding: the free tier. 50 credits will tell you if you like it.
- a few evenings a week on side projects: Pro at $20/mo.
- topping up Pro most months: Pro+ at $40/mo. that's 2,000 credits, where Pro plus 1,000 add-on credits would cost you $60.
- using it most of the working day: step up to Pro Max at $100/mo, and keep an eye on the dashboard.
- a heavy agent user who'd otherwise buy lots of add-ons: Power at $200/mo.
Kiro vs the other $20 coding agents
| free way in | entry plan | how usage works | numptr rank | |
|---|---|---|---|---|
| Kiro | 50 credits a month | Pro $20/mo (1,000 credits) | monthly credits, $0.04 add-ons | #9 (7.0) |
| Claude Code | none, needs a paid Claude plan | Claude Pro $20/mo ($17/mo billed annually) | usage limits on your Claude plan | #1 (9.0) |
| Cursor | limited agent and chat requests | Plus $8/mo (Grok models only), Premium $30/mo | weekly-refreshing pool shared with Grok | #2 (8.5) |
| GitHub Copilot | 2,000 inline suggestions a month plus limited chat and agent use | Pro $10/mo ($15 of GitHub AI Credits) | monthly GitHub AI Credits, 1 credit = $0.01 | #4 (8.0) |
Kiro's selling point is the spec workflow, not the price. if you want the strongest agent for repo-wide graft, Claude Code is our #1 (see Claude Code pricing). if you want an ai editor, Cursor is our #2. if you want the cheapest serious option, GitHub Copilot Pro is $10. and if you already pay for ChatGPT, OpenAI Codex is in the box (see Codex pricing). every plan from every coding agent is on the ai coding agent price sheet.
