Kiro offers five distinct service tiers designed to meet different development needs: Kiro Free, Kiro Pro, Kiro Pro+, Kiro Pro Max, and Kiro Power. Each tier provides progressively more capabilities.
New Kiro users automatically start at the perpetual Kiro Free tier.
Credits are consumed fractionally based on each request. Simple edits and shorter prompts will use fewer credits than complex, lengthy tasks. This means that fractional credits allow you to get more value from your credit allocation.
| Tier | Credits | Add-on credits |
|---|---|---|
| Free | 50 | Not available |
| Pro | 1,000 | Available to purchase |
| Pro+ | 2,000 | Available to purchase |
| Pro Max | 5,000 | Available to purchase |
| Power | 10,000 | Available to purchase |

Note the following billing practices when you subscribe, downgrade, unsubscribe, and use add-on credits.
If you are on the Kiro Free tier, have never upgraded before, and upgrade to a paid tier mid-month, you are charged a prorated fee but immediately get access to your new plan's full credit limits. For example, if you subscribe to Pro on April 15th, you'll be charged half the subscription fee and receive all of the credits for that tier.
If you upgrade again within the same first month (for example, from Pro to Pro+ on April 20th), you'll get backdated prorated fees and access to the full credit limits of the higher tier, as if you directly upgraded to Pro+ on April 15th. After that initial month, you'll be charged the full amount.
If you are on any paid tier and upgrade to a higher tier, you are charged a retroactive fee for the entire month based on the price difference. For example, upgrading from Pro to Pro+ charges you the subscription fee difference, and Kiro recalculates the entire month's usage under the new tier's credits.
If you purchased add-on credits before upgrading, they remain in your balance. After the upgrade, Kiro uses your new plan's higher credit allocation first, so your add-on credits are preserved for future use rather than being consumed immediately.
If you downgrade from a higher tier to a lower tier mid-month, you are charged the full fee for the current month. For example, if you downgrade from Pro+ to Pro on June 2nd, you'll be charged the full Pro+ subscription fee for June. From July onward, you will be charged the Pro fee.
For all tiers, your usage cap renews at the beginning of the next billing cycle.
