Kiro is an agentic IDE that helps you go from prototype to production with spec-driven development. From simple to complex tasks, Kiro works alongside you to turn prompts into detailed specs, then into working code, docs, and tests—so what you build is exactly what you want and ready to share with your team. Kiro's agents help you solve challenging problems and automate tasks like generating documentation and unit tests. With Kiro, you can build beyond prototypes while being in the driver's seat every step of the way.

📝 Release notes (0.12.333)
Parallel Task Execution, Quick Plan, and Requirements Analysis
This release makes Kiro Specs faster to start, faster to finish, and harder to get wrong. Run independent tasks concurrently for faster execution, skip approval gates with Quick Plan when you already know the scope, and catch logical inconsistencies in your requirements before they become implementation problems.
Parallel Task Execution
Run all Tasks now runs independent tasks concurrently instead of one at a time. No configuration needed - click Run all Tasks and Kiro handles the rest. It analyzes your task list for dependencies and groups independent tasks into parallel waves, each running in its own isolated context. For specs with 4+ independent tasks, this can cut execution time by up to 4x. Learn more ->
Quick Plan
A new Spec session mode for when you already know what you want to build. Kiro generates requirements, design, and tasks in a single pass without approval gates between phases. It asks clarifying questions up front (scope, constraints, edge cases) then produces all three artifacts. You land directly on the task list, ready to build. Same traceability and correctness that Specs provide, with a tighter feedback loop. Learn more ->
Analyze Requirements
A deep analysis pass that catches logical inconsistencies, ambiguities, conflicting constraints, and gaps in your requirements before you move to design. Kiro uses automated reasoning to find issues that are hard to catch in a read-through - ambiguous language, conflicting constraints, and logical gaps. Results appear in chat as clarifying questions you can resolve in seconds. Learn more ->
