Kiro
Kiro is an agentic software-engineering toolset, an IDE, a CLI and cloud sessions, that turns prompts into executable specs, validates code correctness, and works across large codebases with parallel agents, positioned as a step beyond basic AI code completion.
- Spec-first approach makes intent reviewable
- Correctness checks aim beyond unit tests
- Explicit, configurable trust model
- Parallel agents for larger changes
- Public page is thin on hard detail
- More setup than a simple autocomplete
- Credit burn needs real-use measurement
