mux - coding agent multiplexer

A desktop application for parallel agentic development.

Features:

• Isolated workspaces with central view on git divergence
• Local: git worktrees on your local machine (docs)
• SSH: regular git clones on a remote server (docs)
• 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.
