Emdash
Open-Source Agentic Development Environment
Emdash is a free, open-source agentic development environment for running coding agents such as Claude Code and Codex. It addresses the problem of coordinating multiple agent tasks by running them in parallel, scheduling recurring work, and reviewing changes in one place. It supports 25+ coding agents, works on macOS, Windows, and Linux, and can connect to remote machines via SSH.
Key features include parallel agent runs in isolated Git worktrees, an in-app browser for previewing local and remote apps, diff and PR review, CI monitoring, and automations for recurring tasks. It integrates with Linear, Jira, GitHub, Notion, and Asana for issue context, and supports prompts, skills, and MCP tools. It also includes a built-in file editor and SSH-based remote execution. Emdash is free and open source, with no paid editions or usage-based pricing mentioned.
