Detailed overview

Kiro is an AWS-built agentic development environment that turns prompts into structured requirements, designs, sequenced tasks, code, documentation, and tests. It checks requirements for contradictions with automated reasoning, validates behavior with property-based tests, and implements tasks with parallel agents locally or in the cloud. It works through a desktop IDE, CLI, web, mobile, and Kiro Crew, with specs, steering, hooks, MCP, AGENTS.md/Skills.md, and Agent Client Protocol (ACP) support for adapting agents to team workflows.

Pricing details

Kiro uses a credit-based pricing model with no daily or weekly rate limits and pre-paid overages; a $20 credit is offered for first-time paid plan signups via social login or Builder ID. Free installable experiences are available; web, mobile, team, and enterprise access may vary by plan. See kiro.dev for current availability.
