How the two compare on the things that decide whether your setup carries over: open standards, license, models and where they run.

Key differences

  • OpenCode is open source (MIT); Kiro is proprietary. If you need to self-host, audit or fork the harness, that settles it.
  • OpenCode also runs in Terminal, Desktop; Kiro also runs in CLI.
  • OpenCode supports AGENTS.md; we have not verified it for Kiro.
  • Both support MCP, Agent Skills, ACP, so MCP servers, skills and repo instructions you set up carry over if you switch.
