Open-Source Agentic Development Environment·emdash.sh

Emdash is a free, open-source agentic development environment that lets developers run multiple coding agents (like Claude Code and Codex) in parallel, each in its own Git worktree. It supports scheduling recurring agent work, an in-app browser for previewing apps, a library of reusable prompts/skills/MCP servers, issue tracker integrations, and diff/PR review workflows. It is a desktop application available for macOS, Windows, and Linux.
