Product Positioning & Context

AI Executive Synthesis
Orchestrates multiple AI agents as a team (with dashboard, chat, kanban, live terminal), supporting various models (Claude Code, OpenAI Codex, Cursor Agent, opencode, local models). Aims to reduce dependency on single company APIs for AI workflows.
This open-source multi-agent harness directly addresses the critical B2B pain point of vendor lock-in and limited control within AI development ecosystems. By providing a framework to orchestrate diverse AI agents from multiple providers (including local models), it empowers developers to build resilient, model-agnostic workflows. The 'CEO agent' concept for autonomous worker management and the comprehensive web dashboard (chat, kanban, live terminal) enhance operational efficiency and oversight for complex AI projects. This tool capitalizes on the growing demand for flexible, extensible AI infrastructure, mitigating risks associated with proprietary model access and fostering a more open, competitive AI development landscape. Its Go-based, lightweight architecture further appeals to performance-conscious teams.
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, https://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!
