Key differences

  • Roo Code is open source (Apache-2.0); Kiro is proprietary. If you need to self-host, audit or fork the harness, that settles it.
  • Kiro also runs in CLI.
  • Roo Code supports AGENTS.md; we have not verified it for Kiro.
  • Kiro supports ACP; we have not verified it for Roo Code.
  • Both support MCP, Agent Skills, so MCP servers, skills and repo instructions you set up carry over if you switch.
