Kiro is an agentic AI with an IDE and CLI that helps you go from prototype to production with spec-driven development. It works alongside you to turn prompts into detailed specs, then into working code, docs, and tests, automating tasks like generating documentation and unit tests.

What is spec-driven development? How is it different from vibe coding?

Spec-driven development defines requirements, system design, and tasks before writing code, explicitly documenting reasoning and implementation decisions. This allows Kiro to implement more complex tasks in fewer shots, addressing limitations of 'vibe coding' like misinterpreting context or lacking decision tracking.

How can I get started with Kiro?

Download the installer for your operating system (macOS or Linux), and log in with GitHub, Google, AWS Builder ID, or AWS IAM Identity Center. An AWS account is not required to use Kiro.

What programming languages does Kiro support?

Kiro supports a variety of programming languages including Python, Java, JavaScript, TypeScript, C#, Go, Rust, PHP, Ruby, Kotlin, C, C++, shell scripting, SQL, Scala, JSON, YAML, and HCL.

Can I import settings from my existing IDE?

Yes, Kiro is based on Code OSS, allowing you to import your VS Code settings, themes, and Open VSX compatible plugins during the onboarding process.
