Which tool for which job

Kiro wins when you want spec-first agent coding with a free tier and clear credit pricing, or you are moving off Amazon Q Developer's IDE plugins.

Unity's AI tools wins when you already work in Unity 6 and want an in-editor assistant or an official plugin for an outside coding agent.
