Mux
Run parallel coding agents, each with its own isolated workspace.
Mux, by Coder, is an open-source desktop and browser app for running multiple AI coding agent sessions in parallel, each in an isolated workspace — a local directory, git worktree, SSH remote, Docker container, or Coder cloud workspace. Rather than wrapping external CLIs, Mux runs its own provider-agnostic agent loop with your API keys across Claude, GPT-5/Codex, Gemini, Grok, DeepSeek, local Ollama and 300+ OpenRouter models. A unified UI shows git status across workspaces, with Plan Mode, Best-of-N and session forking; a self-hosted server mode makes everything reachable from the browser.
