About Kiro

Kiro is an agentic development environment built and operated by a team within Amazon Web Services. It is available as an IDE based on Code OSS, a command-line interface, a web app that runs agent sessions in cloud sandboxes, and a preview iOS app. Its central idea is spec-driven development: a prompt is turned into requirements, a technical design and a sequenced task list, which agents then implement, in parallel where possible.

Best for

  • Turning feature ideas into structured specs and tasks before agents write code in large codebases
  • Feature planning to implementation: Turn a feature request into requirements, design and tasks, then have agents build it in parallel.
  • Automated pull request review: Run the headless CLI in CI/CD to review pull requests and fix bugs.
  • Background maintenance: Use hooks to keep documentation and tests updated as code changes.
  • Long-running cloud tasks: Start Kiro Web sessions that continue after the laptop is closed, then check progress from a phone.
  • Enterprise governed AI coding: Roll out with SSO, usage dashboards and cost controls for an organization.

Not ideal for

  • Non-programmers, teams that need Android mobile access, users who want flat unlimited usage

Popular with

Pros and cons

Pros

  • Spec-driven workflow produces requirements, design and task lists before code is written.
  • Based on Code OSS, so VS Code settings, themes and Open VSX extensions carry over.
  • Same credit pool works across IDE, CLI and Web with no separate cloud compute charge.
  • Multiple model families, including open-weight options, with an Auto mode.
  • Free tier with 50 credits and downloadable apps on macOS, Windows and Linux.

Cons

  • Credits can run out quickly on complex spec tasks; costs vary by model and monthly credits do not roll over.
  • Free tier excludes premium models and is limited to open-weight models and Claude Sonnet 4.5 under rate limits.
  • Mobile app is iOS-only, in preview, and needs iOS 26 or later.
  • Cloud sessions are only available in US East (N. Virginia), and Enterprise pricing is not published.

Frequently asked questions

How does Kiro pricing work?

Kiro is credit-based. Free gives 50 credits; Pro is $20/month (1,000 credits), Pro+ $40 (2,000), Pro Max $100 (5,000) and Power $200 (10,000). Extra credits cost $0.04 each. Unused monthly credits do not roll over.

Which models does Kiro support?

The default is Auto, which mixes frontier and specialized models. Users can also select Anthropic Claude, OpenAI GPT and open-weight models such as DeepSeek, MiniMax, GLM and Qwen. Availability varies by country or region.

Is my code used to train models?

Per the FAQ, content from paid Pro-tier users signing in through IAM Identity Center or an external identity provider is not used. Free users and paid users who sign in with a social login or AWS Builder ID may have content used for service improvement and can opt out at any time.

Do I need an AWS account to use Kiro?

No. The homepage states no AWS account is required; sign-in is available with social login or AWS Builder ID, and organizations can use IAM Identity Center.

Where can I use my Kiro subscription?

In the Kiro IDE, CLI, Web, Crew, ACP-compatible IDEs and CI/CD automation such as code review. Routing requests through third-party harnesses such as OpenClaw is not permitted.

Is there a mobile app?

Kiro for iOS is in preview, distributed to a limited number of people through TestFlight. It requires iOS 26 or later and a paid Pro-tier account. Android is not available yet.
