AWS's spec-driven agentic IDE that transforms natural language into structured requirements, designs, and tasks—enabling autonomous AI agents to work for hours or days with persistent context.
Watch Kiro's spec-driven approach: first generating structured requirements and design, then implementing with full traceability.

| Core Competency | Agentic Workflows, Spec-Driven Development, Enterprise Development, AWS Integration, Long-Running Tasks |
|---|---|
| AI Architecture | Claude Sonnet 4.5 as primary model, with Auto mode that combines frontier models with prompt caching to optimize quality, latency, and cost. |
| Context Window | Large context support through Claude Sonnet 4.5. Persistent context across sessions enables multi-day autonomous work without losing project understanding. |
| Deployment | Standalone IDE (Code OSS-based) for macOS, Windows, Linux. CLI available for macOS and Linux. No AWS account required—sign in with GitHub, Google, AWS Builder ID, or IAM Identity Center. |
| Offline Support | Cloud-based, requires internet connection. Core agentic features depend on cloud AI inference. |
| IDE Integration | Kiro is a standalone IDE based on Code OSS. Supports VS Code settings import, Open VSX extensions, and existing themes. CLI available for terminal workflows. |
| Company Maturity | 1 years |
| Pricing Model | Standard - Individual developers |

Kiro represents AWS's strategic entry into agentic coding, differentiated by its unique spec-driven development approach. Rather than jumping straight to code, Kiro first generates structured specifications (requirements, design, tasks) that guide implementation—creating an auditable trail from intent to code. The autonomous agent's ability to maintain persistent context across hours or days of work addresses a key limitation of other tools. Powered by Claude Sonnet 4.5 with AWS enterprise backing, it's positioned for teams needing traceable, specification-compliant AI-generated code. Note: Score reflects public preview status—may increase as the tool reaches GA.
Kiro offers solid AI development capabilities with specific technical strengths. Best suited for developers requiring advanced AI assistance in their primary development workflow.
