Kiro

A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.

Specs that verify intent

You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.

Persistent agents and Crew

Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.

Workflows and adversarial review

Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.

Runs where you work

Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.
