Kiro Pricing and Free Tier: Plans, Limits, and What You Get in 2026

Kiro offers a free tier with 50 agent interactions per month, a Pro plan at $19/month, and a Pro+ plan at $39/month. It's built on VS Code and targets developers who want agentic spec-driven workflows. The free plan is genuinely usable for solo projects; the paid tiers remove interaction caps and add priority access.

• Free: 50 agent interactions/month, no credit card required
• Pro: $19/month, 1,000 agent interactions/month
• Pro+: $39/month, unlimited interactions (fair-use policy applies)

Kiro pricing plans breakdown

Kiro launched in preview in mid-2025 as an AWS-backed AI IDE. Its pricing model follows the pattern set by Cursor and Windsurf: a meaningful free tier to get developers hooked, then paid tiers gated by interaction volume.

Plan	Price	Agent Interactions	Key Features
Free	$0/month	50/month	Specs, hooks, auto-completions, basic agent tasks
Pro	$19/month	1,000/month	All Free features + priority queue, more model access
Pro+	$39/month	Unlimited (fair use)	All Pro features + highest priority, extended context

These figures are drawn from Kiro's official pricing page. Plans are billed monthly; annual billing may be available at a discount as the product exits preview.

What counts as an "agent interaction"?

An agent interaction in Kiro is any request that triggers the agentic loop: generating a spec, running a hook, asking the agent to implement a feature, or executing a multi-step task. Simple inline completions (autocomplete suggestions as you type) do not count against your interaction quota.

This distinction matters. You can use Kiro for day-to-day coding with autocomplete on the free plan without burning through your 50 monthly interactions. The cap only kicks in when you engage the full agent for spec creation or autonomous task execution.

Kiro free tier: what you actually get

The free tier is not a trial. There's no expiry date and no credit card required to sign up. You get:

• 50 agent interactions per month (resets on the 1st of each month)
• Access to Kiro's core differentiators: specs, hooks, and steering files
• VS Code-compatible extension (works with existing keybindings and extensions)
• Access to Claude Sonnet and other supported models (subject to availability)
• AWS integration for teams already in the AWS ecosystem

For a solo developer running occasional agentic tasks, 50 interactions can stretch across a full month of feature work. For daily driver usage, Pro is the realistic minimum.

How Kiro's pricing compares to alternatives

Kiro enters a crowded market. Here's how its pricing stacks up against the main alternatives developers consider:

Tool	Free Tier	Entry Paid Plan	Pricing Model
Kiro	50 agent interactions/mo	$19/month	Interaction-based
Cursor	2-week trial	$20/month	Fast requests + premium model usage
Windsurf	Limited credits/mo	$15/month	Credit-based (flows + actions)
GitHub Copilot	2,000 completions/mo	$10/month	Per seat, completion-focused
OpenAI Codex CLI	Limited preview access	Token-based via API	API token consumption

Kiro's $19 Pro plan is competitive with Cursor at $20/month. The key differentiator isn't price: it's the spec-driven, hook-based agentic model that Kiro is built around, which has no direct equivalent in Cursor or Copilot. See our Claude Code vs Cursor pricing comparison for more context on how agentic tools price their tiers.

When do Kiro usage limits reset?

Kiro resets agent interaction counts on a monthly calendar cycle, on the 1st of each month. There is no rolling 30-day window. If you exhaust your 50 free interactions on July 15th, they reset on August 1st, not August 14th.

Pro and Pro+ users are less likely to hit hard resets because their caps are much higher (1,000/month and unlimited respectively), but the same calendar-based reset applies to the 1,000-interaction Pro cap.

Kiro's core features across all plans

Kiro's product differentiation comes from three concepts that exist on every plan:

Specs

Before the agent writes code, it generates a structured specification: requirements, design, and task breakdown. This reduces hallucinated implementations and makes large features more predictable. Specs persist in your repo as markdown files.

Hooks

Hooks are event-driven automations. You define triggers (e.g., "when a file changes", "before a git commit") and the agent runs a task automatically. Similar to GitHub Actions, but scoped to the IDE and agent-aware.

Steering files

Steering files let you encode project conventions: code style, architecture rules, preferred libraries. The agent reads them on every task, reducing the need to re-explain context in every prompt.

All three features are available on the free tier. The paid tiers primarily increase how often you can invoke the agent, not what it can do.

Is Kiro worth paying for?

The free tier is the right starting point for most developers. 50 agent interactions is enough to evaluate whether Kiro's spec-driven workflow fits how you build. If you find yourself hitting the cap mid-project, that's a signal the tool is working for you, which makes the $19 Pro plan a straightforward decision.

Pro+ at $39/month makes sense for teams or solo developers with heavy daily agent usage. The unlimited interaction model removes the mental overhead of counting tasks, which is a real productivity factor.

For comparison, if you're also evaluating Claude Code: Claude Code runs on Anthropic's API and has its own usage model tied to your Claude Pro or Max subscription. See Claude Cowork pricing and limits and whether Claude Code is free with Claude Pro for the full picture.

Key takeaways

• Kiro free tier: 50 agent interactions/month, no expiry, no card required
• Pro plan: $19/month for 1,000 interactions
• Pro+: $39/month, unlimited (fair-use)
• Autocomplete does not count against interaction limits
• Usage resets on the 1st of each calendar month
• Specs, hooks, and steering files are available on all plans including free
• Pricing is competitive with Cursor ($20/mo) and more generous than a pure API-token model
