## Definition

Kiro is AWS's agentic AI IDE, built on Code OSS and pitched as a fix for "the chaos of vibe coding." Its headline bet: specs first, code second. Every task starts as a generated requirements + design + test plan that the agent then executes and validates. 

AWS [announced Kiro on July 14, 2025](https://kiro.dev/blog/introducing-kiro/) in free preview — the launch hit #1 on Hacker News with 1,063 points — and took it [generally available on November 17, 2025](https://kiro.dev/blog/general-availability/) with a paid CLI, property-based testing, checkpointing, and team management via AWS IAM Identity Center. Pricing tiers: Free, Pro $20, Pro+ $40, Power $200 per month.

## Example

In a typical Kiro session, a developer types a one-line intent ("add OAuth2 to this Flask app"). Kiro generates a spec — a requirements list, a design doc, and a task breakdown with tests — then executes each task as an agent, checkpointing after every step so the developer can rewind any change without losing adjacent progress.

## Analogy

If Cursor is a fast co-pilot, Kiro is a project manager that drafts the blueprint before anyone picks up a hammer.

## Why it's emerging now

Kiro went GA on November 17, 2025, shipped a CLI and property-based testing, and anchored the "spec-driven development" category alongside Spec-Kit and Tessl — but AWS is still fighting its own pricing reputation and the homograph SERP (ski resort, anime name) for the bare query.
