When Does Kiro Usage Reset? Credits, Billing Cycle, and Limits Explained

Kiro usage resets on a monthly cycle: paid plans (Pro, Pro+, Power) refill credits on your subscription's monthly billing anniversary, while the free tier resets at the start of each calendar month. This matters for developers because Kiro, AWS's agentic IDE, runs on a credit system rather than the rolling multi-hour windows used by tools like Claude Code.

• Kiro is built around "vibe" and "spec" interactions, each consuming credits at different rates (Kiro pricing).
• Free tier credits reset monthly and do not roll over to the next month.
• Paid plan credits reset on your renewal date, not the calendar month, unless your billing started on the 1st.

What is Kiro and how does its usage system work?

Kiro is an AI-powered IDE from AWS built for spec-driven development, where you write requirements and design docs that the agent turns into working code. Instead of time-based rate limits, Kiro meters usage through credits that get consumed per "vibe" (quick, conversational) request and per "spec" (multi-step, planned) task, with specs typically costing more credits than a single vibe prompt (Kiro documentation).

When does Kiro's free tier usage reset?

Kiro's free tier credits reset at the start of each calendar month, independent of when you signed up. Unused credits do not carry over, so there's no benefit to hoarding them near the end of the month. This calendar-month reset is standard among freemium dev tools (similar to how Cursor's free tier behaves) and is confirmed on Kiro's official pricing page (kiro.dev/pricing).

When do paid Kiro plans reset?

Paid Kiro plans reset on your monthly billing date, i.e., the same day each month that you first subscribed or last upgraded, not the 1st of the calendar month. If you subscribed on the 17th, your credits refill on the 17th of every following month. This is the common pattern for subscription-based SaaS billing and mirrors how Anthropic resets Claude Pro usage limits on an anniversary basis rather than a fixed calendar date.

Plan	Price	Reset cadence	Rollover
Free	$0	Calendar month	No
Pro	Monthly subscription	Billing anniversary	No
Pro+	Monthly subscription	Billing anniversary	No
Power	Monthly subscription	Billing anniversary	No

Exact credit allotments per tier change as AWS iterates on pricing, so confirm current numbers on the official pricing page before budgeting a team's monthly usage.

What happens if you run out of credits before the reset?

If you exhaust your monthly credits early, Kiro either blocks further agentic requests until reset or offers on-demand overage pricing on paid tiers, depending on your plan configuration (Kiro docs). Free tier users simply have to wait for the next calendar month, while Pro/Pro+/Power subscribers can typically purchase additional credits or upgrade tiers mid-cycle to keep working.

Because specs consume more credits than vibes, teams that lean heavily on multi-step spec workflows burn through monthly allotments faster. Switching lower-stakes tasks to vibe mode, or batching spec work earlier in the billing cycle, is a practical way to avoid a mid-month lockout.

How is Kiro's reset different from Claude Code or Cursor?

Kiro resets credits monthly with no short-term window, while Claude Code uses a 5-hour rolling usage window plus a separate weekly cap, and Cursor blends monthly "fast request" allotments with per-request cost multipliers by model. If you're used to Claude Code's tighter rolling resets, Kiro's monthly cycle feels more forgiving day-to-day but less forgiving if you front-load a big spec-driven refactor early in the cycle and have nothing left for the back half of the month.

How do you check your exact Kiro reset date?

Check your exact reset date inside Kiro's account or billing settings, where AWS displays current credit balance and the next refill date tied to your subscription. The in-app usage panel is the authoritative source since AWS has adjusted plan details since Kiro's 2025 launch, and the pricing page reflects the latest tiers (kiro.dev/pricing).

Key takeaways

• Free tier: resets on the calendar month, no rollover.
• Paid tiers (Pro, Pro+, Power): reset on your monthly billing anniversary, not the 1st.
• Spec tasks cost more credits than vibe requests, so heavy spec usage drains the monthly pool faster.
• Running out early means waiting for reset (free) or buying overage/upgrading (paid).
• Always confirm your specific reset date and remaining credits in Kiro's account settings, since AWS has revised pricing tiers since launch.
