> Mux is an open-source tool for running parallel coding agents, each with its own isolated workspace, accessible from your browser or desktop.

Mux is an open-source, LLM provider-agnostic platform that lets developers run multiple coding agents in parallel, each operating in its own isolated workspace. Built by Coder Technologies, it provides a central view of git status updates across all agents and supports a wide range of leading AI models. Mux is licensed under AGPL-3.0 and is designed for developers who want to maximize throughput by parallelizing agentic coding tasks.

- **Parallel Coding Agents**: *Spin up multiple agents simultaneously, each in an isolated workspace, to tackle different tasks or approaches at once.*
- **Multi-Model Support**: *Works with a range of LLMs including Claude (sonnet-4, opus-4), xAI Grok, and OpenAI GPT-5, letting you choose or mix providers.*
- **Isolated Workspaces**: *Each agent gets its own sandboxed environment with a centralized git status view, keeping work organized and conflict-free.*
- **Workspace Forking**: *Fork existing workspaces to branch agent work, enabling "Best of N" strategies where multiple agents attempt the same task.*
- **Agent Skills & Instruction Files**: *Define reusable skills and instruction files to guide agent behavior and enforce project-specific conventions.*
- **Plan Mode**: *Review and approve agent plans before execution, giving developers human-in-the-loop control over agentic actions.*
- **MCP Server Integration**: *Configure Model Context Protocol (MCP) servers to extend agent capabilities with external tools and data sources.*
- **VS Code Extension**: *Integrates directly with VS Code via an extension and supports the Agent Communication Protocol (ACP) for editor interoperability.*
- **Policy Files & Project Secrets**: *Manage access controls, secrets, and behavioral policies at the project level for secure agentic workflows.*
- **Rich Markdown Outputs**: *Agents produce rich outputs including Mermaid diagrams and LaTeX, making results easy to review and share.*
- **GitHub Actions Integration**: *Run Mux agents as part of CI/CD pipelines via GitHub Actions for automated agentic workflows.*
- **CLI & Keyboard Shortcuts**: *Full CLI support and a comprehensive keyboard shortcut system for power users managing many agents at once.*
