Conductor is a multi-agent orchestration harness developed by Melty Labs. It is designed to manage, coordinate, and execute parallel coding agent workflows across local environments and cloud-based execution sandboxes. In day-to-day operations, Conductor serves as a control plane for AI-assisted development. Rather than executing a single agent prompt in a static shell, developers can dispatch tasks across multiple underlying runtimes—such as Claude Code, OpenCode, Codex, or Cursor-based workflows—using their own API keys and accounts. Workspaces can run locally on macOS or inside isolated Firecracker microVMs in Conductor Cloud, allowing agents to execute shell commands, run test suites, and prepare code diffs independently of the local machine. What sets Conductor apart from standalone terminal agents is its orchestration model and collaborative interface. It supports multi-agent workflows where different models can critique or build upon each other's outputs, alongside multiplayer workspace sharing (⌘⇧C) so multiple developers can supervise or prompt agents simultaneously within the same session. Conductor is commercial software offering a macOS desktop application, Conductor Cloud sandboxes, and an automation API, operating on a Bring Your Own Keys (BYOK) and bring-your-own-subscription model for model consumption.
