What is Kiro?
Kiro is an agentic AI IDE built and operated by AWS that aims to move developers beyond AI-assisted coding toward agentic engineering.
It is designed for developers and teams who want a more structured, reliable approach to building software with AI, and its defining idea is spec-driven development: Kiro turns prompts into detailed, executable specifications covering structured requirements, architectural designs, and sequenced tasks, then implements those tasks with parallel agents and validates the results with property-based tests that catch edge cases unit tests miss.
Built on Amazon Bedrock, Kiro uses foundation models from Amazon and third parties and includes the features expected of a modern AI code editor, such as Model Context Protocol support for connecting specialized tools, steering rules to guide AI behavior across a project, agent hooks to automate actions, and agentic chat for ad-hoc tasks.
It also offers a web experience in addition to the IDE. Developers use Kiro to plan and build features with traceable specs, work across large codebases with parallel agents, generate tests and documentation, and ship code that better matches intent.
Pros include a rigorous spec-driven workflow, AWS-grade security and reliability, parallel agents, and strong tooling integration. Cons include that the spec-first approach adds upfront structure that may feel heavy for quick scripts, and that credit-based usage can require monitoring on larger projects.
Kiro uses a credit-based freemium model with a free tier and paid plans. Pricing changes often, so check the official site for current plans.
