Kiro

Agentic development environment that turns a prompt into requirements, a design and tasks for parallel agents.

Overview

Kiro is an agentic development environment from AWS, available as a desktop editor, a terminal tool, a web agent and a phone app. It is built around spec-driven development: a prompt becomes requirements, a design and tasks, which are then handed to parallel agents that write the code.

Its autonomous agent can clone repositories into cloud sandboxes, coordinate sub-agents and open pull requests. Agents run on the user’s machine or in the cloud. Kiro also writes property-based tests, which check a rule across many inputs rather than a few examples.

Pricing is based on monthly credits, from a free tier up to $200 a month. Users can extend Kiro with MCP servers, skills and tool packs.
