Verified Oct 12, 2026 · Kiro
Kiro is an agentic coding environment from Amazon Web Services built around spec-driven development: prompts become requirements, a design and task lists before agents write code. It ships as a desktop IDE, a CLI and a browser version, and developers use it to keep AI-generated code tied to documented intent.
Turns a prompt into requirements with acceptance criteria, a technical design and sequenced tasks that agents then implement.
Checks requirements for contradictions and gaps, then tests behavior against rules that must hold for all inputs, not a few examples.
Steering files load your conventions into every session, and hooks trigger agent actions automatically when events occur.
On paid plans, agents run in isolated cloud sandboxes, work across GitHub and GitLab repos and deliver pull requests.
Run the same agent in a terminal, hand work off to cloud sessions, or use it headless in CI/CD for reviews and fixes.
Auto mixes models to balance quality, speed and cost, or you pick Claude, GPT-5.6 or open-weight models with credit multipliers.
Kiro is AWS’s development environment for working with AI agents in a structured way. Instead of jumping straight from a prompt to code, spec mode produces requirements, a design and tasks that you approve, and agents implement them in parallel.
The IDE is built on Code OSS and runs on macOS, Windows and Linux, with native ARM64 builds since IDE 1.1 in September 2026. Kiro CLI, Kiro Web and Kiro Crew, an open-source persistent agent workspace, share the same credits.
Every tier is priced by monthly credits rather than request counts. Paid plans renew on the 1st of each calendar month, and prices exclude VAT and sales tax. Pricing in AWS GovCloud (US) Regions is about 20% higher.
