Emdash
Open-source agentic development environment for orchestrating coding agents
Emdash is an open-source desktop application that lets developers run multiple coding agents in parallel, each isolated in their own Git worktree. It supports 25+ coding agents including Claude Code, Codex, Cursor, and Gemini, with built-in MCP server connections, CLI auto-detection, and a file editor. It is backed by Y Combinator and has over 840K downloads.
Emdash provides a dashboard that detects installed agent CLIs automatically and runs each agent in its own isolated Git worktree, allowing parallel execution and easy management from a single interface.
