An open-source multi-agent harness in Go
Raw Developer Origin & Technical Request
Hacker News
Apr 9, 2026
Hey HN. I built an AI agent harness over the past few months and I'm open sourcing it today.Some context on why. I've been building with Claude Code daily using this harness. It orchestrates multiple AI agents as a team, with a dashboard, chat, kanban board, the works. I used it to build a full SaaS product (MyUpMonitor, myupmonitor.com in about 24 hours of focused coding.Then yesterday Anthropic announced Mythos and decided to keep it behind closed doors. Meanwhile I'm paying for Claude and I can't access their best model. I don't think that is nice at all...So I'm open sourcing the harness with support for both Claude Code and OpenAI Codex. The whole point is that you shouldn't be dependent on one company's API to run your AI workflow.What this harness does:
- Spawns and manages multiple AI agents in parallel
- Each agent gets a persona, role, and communication channels
- CEO agent that can hire/fire workers on its own
- Web dashboard with chat, kanban board, and live terminal output
- Supports Claude Code, OpenAI Codex, Cursor Agent, opencode, and local models
- MCP server per worker for tool access
- Written in Go. Two binaries. SQLite. No heavy deps.Would love feedback from anyone working on multi-agent setups or just what you think in general. Thank you!
