Xum - Coding Agent Multiplexer

Important

This project was renamed from Mux to Xum after Mux.com raised a trademark concern. “Mux” is a common technical abbreviation of “multiplexer” and we do not expect confusion between the projects, but chose to rename ours rather than spend more time on the dispute.

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 Xum workspaces directly from VS Code (docs)
Supporting UI and keybinds for efficiently managing a suite of agents
Rich markdown outputs (mermaid diagrams, LaTeX, etc.)

Xum 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.
