A decision for a beginner, not a spec sheet. Scores are our weights. Prices are the public plans, and anything marked verify on the tool page should be re-checked before you pay.
Pick Amp if you want a repo you want an agent to work on in parallel, including while your laptop is closed.
Pick Kiro if you want a web app or automation you will keep in a repo and review as a diff.
A coding agent you can run free on your own machine, or in Amp's cloud.

Individual
Free
VerifiedAll product features. No monthly fee. Pay-as-you-go orbs, or your own runners at no Amp charge. Linked ChatGPT, Claude, and other subscriptions, and bring-your-own-key, with no Amp token fees or limits. No included orb minutes and no included Amp credits.
The Hobby card is on ampcode.com/pricing. Standard orb rates, if you do use cloud machines, are on the orb sizes page and start at $0.08 an hour for a1.tiny.
Individual
$20/mo
Verified45,000 minutes of orb time and $20 of Amp credits, then more credits at provider list price. Unlimited public and private repositories, and your own portal domains. Soft hosting limits on the card are 1 GB of repository storage and 10 GB of monthly transfer.
This is the Individual price shown on the default pricing tab. Included usage does not roll over. The $20 of credits is the amount the pricing card prints for this tier.
Individual
$10/mo
VerifiedThe same Megawatt allowance, at $10 a month for students and teachers. The pricing card shows $10 of included Amp credits when the education discount is applied.
The pricing FAQ says students and teachers can get Megawatt for $10 per month. Left out of budget matching so a general under-$10 question cannot be won by a discount most readers cannot buy.
Individual
$200/mo
Verified480,000 minutes of orb time, which is the Gigawatt tab's minute figure, and $200 of Amp credits. The underlying allowance is 1,000 hours of a1.xxlarge. a1.3xlarge orbs are limited to Gigawatt and Enterprise. Soft hosting limits are 10 GB of repository storage and 100 GB of monthly transfer.
The $200 price is the Gigawatt tier on ampcode.com/pricing. The default tab is Megawatt, so the $200 card is the other Individual tab. A note on the orb details says 10× limits for Gigawatt.

Individual
Free
Verified50 credits a month. Claude Sonnet 4.5 and open-weight models such as Qwen3 Coder Next, DeepSeek 3.2, and MiniMax M2.1, with rate limits. No add-on credits. Kiro Web is not included.
The 50-credit free allowance is on the pricing page and the billing docs. The free tier is not offered on Kiro Enterprise or in AWS GovCloud.
Individual
$20/user/mo
Verified1,000 credits a month. Premium models, including Auto, Claude Sonnet 5, and Claude Opus 5, where those models are available. Add-on credits at $0.04. Kiro Web uses the same credits.
Price is on kiro.dev/pricing. The credit count is on the billing docs. Prices exclude tax. A first upgrade with social login or Builder ID gets a $20 credit toward the subscription, prorated for the partial month.
Individual
$40/user/mo
Verified2,000 credits a month, with the same paid-plan model access and add-on credits as Pro.
Price on the pricing page. Credit count on the billing docs.
Individual
$100/user/mo
Verified5,000 credits a month. The same feature set as Power, including specs, custom subagents, powers, and hooks.
The $100 price and the 5,000-credit count are on the pricing page's tier list, the billing docs, and Kiro's Pro Max announcement.
Individual
$200/user/mo
Verified10,000 credits a month, the largest self-serve pool, plus add-on credits at $0.04.
Price on the pricing page. Credit count on the billing docs. AWS GovCloud is approximately 20% higher and has no free tier. That regional markup is not a separate dollar row here.
Included Megawatt and Gigawatt usage resets at the end of the monthly billing period and does not roll over. Purchased credits expire 12 months after you buy them. A paused orb costs nothing. Amp pauses an idle orb 5 minutes after the agent stops, or 20 minutes after your last interaction, whichever is later.
On Hobby, use your own runner if the bill you are avoiding is orb time. Model limits on a linked ChatGPT or Claude subscription are that vendor's cap, not an Amp cap.
Plan credits renew at the start of the next billing cycle. Paid subscriptions are processed on the 1st of each calendar month. Unused plan credits do not roll over. Add-on credits, which are paid plans only, last 12 months.
On Free, wait for the monthly reset. Add-on credits cannot be bought on this tier, and Kiro Web is not included.
Amp Megawatt and Kiro Pro are both listed at $20/mo.
Amp is for a repo you want an agent to work on in parallel, including while your laptop is closed, people who already pay for ChatGPT or Claude and want to use that subscription inside an agent, and developers who can review agent output and do not need a hosted app builder.
Kiro is for a web app or automation you will keep in a repo and review as a diff, developers who want requirements and tasks written down before the agent edits, and a published monthly credit number, instead of an unpublished quota.
Amp scores 1 out of 5 for someone who does not want to read code. Kiro scores 2 out of 5. Kiro has the higher no-code score. You are starting threads against a project and reading what the agent did. This is not a no-code builder. Specs are written in plain language, and you still end up reading a diff. If code on screen is a dealbreaker, use a browser builder.
Amp: Free to Amp if you bring your own model subscription or key and run on your own machine. Cloud orbs are pay-as-you-go. Hobby includes no orb minutes and no Amp credits. Kiro: 50 credits a month on the perpetual free tier, with Claude Sonnet 4.5 and open-weight models, subject to rate limits. Add-on credits are not available. Kiro Web is not on this plan.
