About agent-orchestrator
Agent Orchestrator is an open source desktop workspace for running and supervising teams of coding agents, written in Go and released under the Apache 2.0 license. It lives in the agent orchestration ecosystem, alongside the coding harnesses it drives, and it is distributed as a local application rather than as a hosted service. The project describes itself as a place to plan, run, and supervise coding agents from one place, giving every coding task its own agent, workspace, and feedback loop.
