mux

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.
