Marmy: A Self-Hosted Mobile App for Managing Multiple AI Coding Agent Sessions

Marmy is a self-hosted application built to manage multiple AI coding agent sessions remotely from a mobile device. The developer created it because existing tools, including Claude Code's Remote Control, were limited to viewing running sessions as conversation windows without the ability to start new sessions, browse files, or receive push notifications.

Architecture and Components

The system consists of two main parts:

• Rust agent: Runs on your machines (laptop, workstation, server, Raspberry Pi).
• iOS app: Runs on your phone to control everything.

Anything running in tmux shows up in the app and can be controlled. While built specifically for Claude Code, it works with any terminal-based AI agent.

Key Features from Source

• Org chart concept: You interact with a manager agent that starts worker sessions, monitors progress, sends instructions, and reports back to you.
• File browser: View code with syntax highlighting directly on your phone.
• Push notifications: Get alerts when sessions finish or need decisions.
• Voice mode: Call into any session hands-free. A Gemini-powered assistant reads status updates, you speak instructions, and it confirms before sending commands.
• Multi-machine support: View and control sessions across multiple machines from one app with a single session list.
• Privacy/security: Open source (MIT licensed), self-hosted, with no data leaving your network.

This tool is for developers who run multiple AI coding agent sessions across different machines and need centralized mobile management beyond simple chat interfaces.
