What is Kiro?
AWS's agentic coding platform across IDE, CLI and web.
Who is Kiro best for?
Kiro is best for developers who want an AI agent to plan a feature as a written spec before it writes the code.
Spec-first feature work
Kiro turns a prompt into requirements, a design and an ordered task list before its agents write code, so bigger features stay close to what you asked for.
Catching bugs unit tests miss
It checks requirements for contradictions and gaps, then writes property-based tests that must hold across all inputs, not just a few examples.
Choosing models by cost
Auto is the baseline rate, and you can switch to Claude, GPT-5.6 or open-weight models that cost from 0.05 to 6 times the credits of Auto.
AWS and enterprise teams
Built and run by AWS, it offers IAM and SSO sign-in, usage dashboards and cost controls, plus a headless CLI that reviews pull requests in CI/CD.
