Overview
Kiro is an agentic engineering platform built by AWS that moves developers beyond simple AI code completion into spec-driven development. It transforms natural-language prompts into structured requirements, architectural designs, and sequenced tasks, then implements them using parallel agents that can run locally or in the cloud.
Developers love Kiro because it enforces correctness before code is written. Using automated reasoning, it checks requirements for contradictions and gaps, and it validates behavior with property-based tests that catch edge cases unit tests miss. The result is maintainable code that matches the original intent, shipped faster and with fewer production surprises.
Kiro is built on open standards and enterprise-grade infrastructure. It supports the Agent Client Protocol (ACP), AGENTS.md, Skills.md, and MCP, and its IDE is compatible with Open VSX extensions and VS Code settings. Backed by AWS, it offers IAM/SSO authentication, governance controls, and predictable credit-based pricing.
Key Features
- Spec-Driven Development: Turns prompts into requirements, architectural designs, and sequenced tasks, then implements them with parallel agents.
- Correctness Validation: Uses automated reasoning to check requirements for contradictions and gaps, plus property-based tests (fuzz-style) to assert rules across all inputs.
- Parallel Agents: Runs multiple agents in parallel on your local machine or in the cloud to accelerate work across large codebases.
- Headless CLI for CI/CD: A headless CLI that reviews PRs and fixes bugs without opening an editor, integrating into existing pipelines.
- Model Flexibility: Choose Anthropic Claude, open-weight models, or Auto mode, which picks the best model per task based on quality, latency, and cost.
- Open Standards & Integrations: Compatible with ACP, AGENTS.md, Skills.md, MCP, Open VSX extensions, and 500+ popular CLIs; pulls context from tools like Figma and Terraform.
- Enterprise-Ready: IAM and SS
