Kiro

Kiro is an agentic AI-powered IDE (built on Code OSS) with an optional CLI for software development teams that want to turn natural language requirements into production-oriented specs, designs, and working code.

Key capabilities include:

• Spec-driven development that converts prompts into structured requirements and acceptance criteria in EARS notation, then maps them into an implementation plan with discrete, dependency-aware tasks.
• Autonomous agents that execute coding work in isolated sandbox environments, including bug analysis, error diagnostics, and fix suggestions, with support for up to 10 concurrent tasks.
• Technical design generation such as architecture and implementation plans, including artifacts like data flow diagrams, TypeScript interfaces, database schemas, and API endpoints.
• Automation and integrations, including agent hooks (for tasks like tests, documentation, and security checks), native MCP support to connect external tools and systems, and compatibility with Open VSX plugins plus VS Code settings import.

Pricing: Freemium with a free plan at $0 (50 credits). Paid plans start at $20/month with 1000 credits (Kiro Pro), $40/month with 2000 credits (Kiro Pro+), and $200/month with 10,000 credits (Power).

Notable for its spec-first workflow that captures decisions and constraints before code generation, aiming to reduce ambiguity common in prompt-only coding while keeping work inside a familiar VS Code compatible environment.
