Kiro
by AWS
Best for developers who want a rigorous, three-phase engineering process. Kiro introduces 'spec-driven development'—forcing users to plan and define intent before agents execute—with credit-based pricing, agent hooks for automation, and access to Sonnet 4/4.5, Haiku 4.5, and Opus 4.5/4.6 models.
