GitHub - coder/mux: A desktop app for isolated, parallel agentic development

Mux - Coding Agent Multiplexer

Mux is a desktop & browser application for parallel agentic development. It enables developers to plan and execute tasks with multiple AI agents on local or remote compute.

Features

• Isolated workspaces with central view on git divergence (docs)
  • Local: run directly in your project directory
  • Worktree: git worktrees on your local machine
  • SSH: remote execution on a server over SSH
• Multi-model (sonnet-4-*, grok-*, gpt-5-*, opus-4-*)
  • Ollama supported for local LLMs (docs)
  • OpenRouter supported for long-tail of LLMs (docs)
• VS Code Extension: Jump into Mux workspaces directly from VS Code (docs)
• Supporting UI and keybinds for efficiently managing a suite of agents
• Rich markdown outputs (mermaid diagrams, LaTeX, etc.)

Mux has a custom agent loop but much of the core UX is inspired by Claude Code. You'll find familiar features like Plan/Exec mode, vim inputs, /compact and new ones like opportunistic compaction and mode prompts.
