Orchino: Local Multi-Agent Orchestration System for Windows with Parallel Browser and UI Automation
Orchino is a local multi-agent orchestration system for Windows that enables parallel execution of browser and Windows tasks without interfering with your current work. The system runs via Windows UI Automation and pure CDP (Chrome DevTools Protocol), never touching mouse, keyboard, or screen focus, allowing you to continue working while it runs.
Key Details
The developer demonstrated the system with this command: "Search Sony earbuds on Flipkart and Amazon, email the results, save to Notepad." The system completed this task in 29.5 seconds using 4 agents with true parallel execution (not sequential).
Execution flow:
- Phase 1 (concurrent): Browser Agent → Flipkart and Browser Agent → Amazon running simultaneously via separate CDP sessions
- Phase 2 (concurrent, after Phase 1): Browser Agent → Gmail and Windows Agent → Notepad running simultaneously
- Results from Phase 1 auto-fed into Phase 2
Architecture
The system features:
- Parallel orchestration with dependency graphs (fan-out, fan-in, sequential, independent — based on goal decomposition)
- OODA loop per agent (~1.2–1.9s per iteration including LLM call)
- 5 domain-scoped agents: Browser, Windows, File, Terminal, System Settings
- Blackboard + SQLite + ChromaDB memory
- Agents run locally, LLM via Cerebras
The project was solo-built by a final year CS student over 6 months.
