Kiro vs OpenCode, side by side
Field	Kiro	OpenCode
Tier	A	A
Why this tier	Its spec-driven approach turns specs into tasks, which keeps bigger vibe-coded projects on the rails. That structure makes it an A-tier pick for larger builds.	It is the best open-source pick on our list if you want to choose your own model. It works with many model providers from the terminal.
Best for	Bigger vibe-coded projects that need structure Working from specs that turn into tasks	Choosing your own model provider People who want an open-source terminal agent
Skip if	You want a quick one-off fix rather than a spec-driven flow You want an open-source agent where you choose the model	You want a managed product with everything set up for you You don't work in the terminal
