Kiro

kiro.dev/

Kiro is AWS's agentic coding tool that turns prompts into executable specifications before code is written, then validates the result with property-based (fuzz) testing rather than relying only on unit tests. The homepage headline, "Move beyond AI coding to agentic engineering," frames three capabilities: converting prompts to specs, catching bugs unit tests miss, and running parallel agents that carry learnings between sessions. It argues "All tests passed" doesn't guarantee code matches intent, using that gap to justify its spec-first approach. The site also states availability across IDE, CLI, web and mobile, a student program it says has reached 132 universities, and no daily or weekly rate limits — specific, checkable claims rather than generic reassurance.
