Maestri is a native macOS app with an infinite canvas for coding agents. Each terminal is a visual node you position freely alongside notes and sketches. Connect agents by dragging a line and they collaborate across harnesses through PTY orchestration. Claude Code talks to Codex. Gemini delegates to OpenCode. Ombro, an on-device AI companion via Apple Intelligence, monitors everything and summarizes what happened while you were away. SwiftUI, custom engine, zero cloud, no telemetry.
