Kiro Pricing and Rate Limits: Free Tier, Pro Plan & Usage Caps (2026)

Kiro's free tier gives you 50 agentic interactions per month at no cost. The Pro plan runs $19/month and lifts that to 1,000 interactions. Rate limits are per-month rolling windows, not daily resets. If you're comparing Kiro against other AI IDEs before committing, this breakdown covers every plan, what counts against your quota, and what happens when you hit the cap.

• Free: 50 interactions/month, no credit card required
• Pro: $19/month for 1,000 interactions
• Enterprise: custom pricing, SSO, audit logs

What plans does Kiro offer?

As of mid-2026, Kiro ships three tiers: Free, Pro, and Enterprise. The Free plan is genuinely usable for small projects, the Pro plan suits daily professional use, and Enterprise adds compliance and team-management features on top of Pro limits. All plans run inside VS Code as an extension, powered by Amazon Bedrock models.

Plan	Price	Monthly interactions	Model access
Free	$0	50	Claude Sonnet (via Bedrock)
Pro	$19/month	1,000	Claude Sonnet + Haiku fallback
Enterprise	Custom	Custom	All Bedrock models, private VPC option

Kiro is built by AWS and launched in 2025. Because it runs on Amazon Bedrock, model routing and rate limiting are handled at the infrastructure layer, which is why limits are expressed in "interactions" rather than tokens or messages.

What counts as an interaction in Kiro?

One interaction is one agentic task: a spec generation run, a full steering-file execution, or a chat prompt that triggers file edits. Inline autocomplete completions do not count against your interaction quota. You can use autocomplete freely on any plan, including Free.

• Counts as an interaction: spec generation, agent runs, hook executions that trigger edits, steering-file tasks
• Does not count: inline code completions, reading files, hover docs, plain chat that doesn't modify files

This means 50 free interactions goes further than it sounds for read-heavy workflows. If you're doing architecture review, code explanation, or exploration, you can stay on Free for a long time. Heavy spec-driven development (Kiro's flagship feature) will burn through 50 interactions quickly on a real project.

How do Kiro's rate limits work?

Kiro enforces a monthly rolling cap, not a daily or hourly one. Your interaction counter resets on the same calendar date each month (your billing anniversary for Pro, the 1st of the month for Free). There is no soft throttle before the hard cap: once you hit 50 or 1,000, agent tasks are blocked until the counter resets.

Secondary rate limits can also trigger at the Bedrock layer. If many users hammer the same model endpoint simultaneously, AWS may apply per-minute throttling that results in a short delay or retry. This is separate from your interaction quota and typically resolves in under 60 seconds. If Kiro appears slow or unresponsive, check AWS Service Health before assuming you've hit your plan cap.

What happens when you hit the Kiro rate limit?

You'll see an in-IDE notification that your interaction quota is exhausted. Autocomplete continues working. You can still browse and read your codebase. To resume agent tasks you either upgrade to Pro, wait for the monthly reset, or purchase additional interaction packs if Kiro offers them at the time.

How useful is Kiro's free tier?

For a solo developer doing occasional spec-driven tasks, 50 interactions/month is enough for light use. It's comparable to Windsurf's free tier, which similarly caps agentic credits but allows unlimited autocomplete. The free tier is best for evaluating Kiro's spec and steering workflow before committing to $19/month.

• Unlimited autocomplete on Free
• Full access to spec generation (counts against quota)
• No time-limited trial window - the free tier is ongoing
• No credit card required to sign up

Is Kiro Pro worth $19 per month?

At $19/month for 1,000 interactions, Kiro Pro is priced between Cursor Pro ($20/month) and GitHub Copilot Individual ($10/month). The value depends entirely on how much you use spec-driven, agentic workflows. If you're doing mostly autocomplete with occasional chat, you might not need Pro. If you're using steering files and running specs daily, 1,000 interactions goes fast on a medium-sized project.

Tool	Pro price	Interaction/message limit	Reset cadence
Kiro Pro	$19/month	1,000 interactions	Monthly
Cursor Pro	$20/month	500 fast requests + slow fallback	Monthly
Windsurf Pro	$15/month	Unlimited flows (fair use)	Monthly
GitHub Copilot	$10/month	No hard agent cap (quota varies)	Monthly

What is Kiro's context window limit?

Kiro uses Claude Sonnet via Amazon Bedrock, which has a 200,000-token context window as of 2026. In practice, Kiro's agent trims context automatically to fit within the model window, prioritizing your open files and steering-file rules. For very large monorepos, context management becomes the binding constraint before you hit your interaction quota.

How does Kiro pricing compare to Cursor?

Kiro and Cursor are $19 vs $20/month - essentially the same. The difference is what you're buying: Cursor's 500 fast requests are model-agnostic (GPT-4o, Claude, etc.), while Kiro's 1,000 interactions are specific to its spec-driven paradigm. If you want flexibility in model choice, Cursor wins. If you want structured, document-driven development workflows, Kiro's higher interaction count at nearly the same price is the better deal. See the full Kiro vs Cursor comparison for a deeper breakdown.

What does Kiro Enterprise include?

Kiro Enterprise is custom-priced through AWS. It adds SSO via IAM Identity Center, audit logging, team-level usage dashboards, private VPC deployment for code that can't leave your network, and dedicated Bedrock capacity (bypassing shared throttles). Teams with compliance requirements (SOC 2, HIPAA, FedRAMP) should evaluate Enterprise. Contact AWS sales for a quote.

How can you stay under Kiro's rate limits?

A few practical habits that reduce unnecessary interaction consumption:

• Draft specs offline first. Write your spec document in a plain text file before triggering Kiro's spec generation. This reduces back-and-forth refinement runs.
• Use steering files for repeatable rules. Put your project conventions in a steering file once. This avoids re-explaining context in every agent run.
• Batch file changes. Group related edits into one agent prompt instead of sequential single-file prompts.
• Reserve autocomplete for exploration. Since autocomplete is unlimited, use it freely for exploring unfamiliar code. Save agent runs for actual edits.

If you're also using Claude Code alongside Kiro, note that Claude Code has its own separate usage window (5-hour rolling limit on Pro and Max plans) that does not share a counter with Kiro.

Key takeaways

1. Kiro Free gives 50 interactions/month with unlimited autocomplete - no credit card needed.
2. Kiro Pro is $19/month for 1,000 interactions, resetting on your monthly billing date.
3. Interactions count agentic tasks only; inline completions are free on all plans.
4. Enterprise pricing is custom via AWS and adds private VPC, SSO, and dedicated capacity.
5. Secondary throttling can occur at the Bedrock layer during peak load, independent of your quota.
6. Context window is 200K tokens (Claude Sonnet via Bedrock), managed automatically by Kiro.
