Marmy: A Self-Hosted Framework for Managing AI Coding Agents Remotely
A developer has open-sourced Marmy, a self-hosted framework designed specifically for managing Claude Code and other AI coding agents remotely. The tool addresses the constraint of needing to stay at a desk to read markdown files and debug code while supervising agents.
How Marmy Works
The framework consists of two main components:
- A Rust agent that runs on all your development machines and hooks into tmux sessions.
- A React Native app that communicates with all your machines.
Key Features from the App
From the mobile app, you can:
- Create, kill, and communicate with any Claude Code sessions or tmux shells.
- View any file within the scope of a tmux shell, including images, rendered markdown, and syntax-highlighted code.
- Start a manager per machine that manages your tmux shells. This is essentially a prompted Claude Code instance with skills and context to manage other shells.
- Talk via voice to any tmux shell using your own Gemini API, with the live model acting as an intermediary.
Developer Context and Motivation
The developer transitioned from Cursor to Claude Code primarily due to Claude Code's superior harness and unbeatable pricing (maxing out a $200 plan versus much higher costs on Cursor for equivalent token usage). While they could have used Claude Code as a VSCode plugin, they found themselves becoming more hands-off with the tool, especially after the Opus 4.5 model release.
Their workflow shifted from writing code to supervising multiple parallel terminals, which they compare to moving from individual contributor work to managerial work. Their main contribution became planning with agents and writing exhaustive specs before letting them write code. Marmy was built to solve the desk-bound problem that remained.
Practical Applications
The developer reports using this setup to manage multiple projects simultaneously, including their startup (framewave.ai), a restaurant SaaS (kitchen-eye.ai), consulting work, building a news website (cedarwatch.news), and creating a full guitar plugin with AI-assisted tone configuration.
The framework is open source, MIT licensed, self-hosted, and designed so that nothing leaves your network.
