A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your 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.
Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.

Describe an app screen in natural language and Stitch produces multiple complete UI designs, including mobile and web layouts.
Upload a sketch, screenshot or existing screen and Stitch produces a matching design interpretation.
Iterate with follow-up prompts to change layout, color themes and components without starting over.
Move generated designs toward implementation with export options suited to design and development handoff.
Builds full-stack web applications from natural language, moving further into functional app development than standard UI design tools.
