Stop renting intelligence. Start owning it.

OpenMono is the official mobile companion for OpenMonoAgent.ai—the world’s first terminal-native, 100% open-source coding agent designed for developers who value privacy, power, and zero-cost scaling. Built on C#/.NET, OpenMono turns your mobile device into a powerful remote command center for your local AI infrastructure.

While other agents charge per-token and lock your code in the cloud, OpenMono is "Dual-Box" native. Run your heavy inference on your home GPU rig (RTX 3090/4090/5090) and control it securely from your phone using our outbound-only relay.

- Unlimited Tokens, Forever: No subscriptions. No rate limits. No surprise bills. Since the model runs on your hardware, every prompt is free.

- Dual-Box Mode: The power of a 27B model on your desk, accessible from your pocket. Works behind any NAT/CGNAT with secure, outbound-only connectivity.

- Docker-Sandboxed Security: Your project is safely mounted in a container. The agent can refactor, test, and deploy—but it can’t escape the box without your permission.

- Deep .NET Intelligence: Powered by Roslyn, OpenMono understands type hierarchies, call graphs, and cross-assembly references like a senior architect.

- 20+ Tools & MCP Support: Full File I/O, Shell access, LSP for C# and TypeScript, and extensibility via the Model Context Protocol (MCP).

- Persistent Sessions: Never lose your flow. JSONL transcripts and snapshot-based file undo ensure your dev history is always intact.

OpenMono isn't just a chatbot; it's infrastructure. Whether you're using Playbooks for automated workflows or performing a deep Roslyn-based refactor, you're using a tool built by developers, for developers.

We believe AI tooling should be a utility, not a subscription. Join the StartupHakk community and help us democratize the AI dev stack.
