Emdash

Emdash is an open-source desktop app for orchestrating multiple coding agents simultaneously, each running in an isolated Git worktree. Backed by Y Combinator and with over 60K downloads, it supports 20+ coding agents including Claude Code, Codex, Cursor, Amp, and GitHub Copilot. Developers can manage parallel agents from a single dashboard, review diffs, commit, and ship without switching tools.

• Parallel Agents — Run multiple coding agents simultaneously, each isolated in their own Git worktree, to tackle different tasks concurrently.
• Kanban Status View — See all running agents at a glance in a Kanban board showing who's done, who needs input, and what's in review.
• Best of N — Send the same task to multiple agents across providers or models and compare results side by side.
• Issue Integration — Pull issues directly from Linear, Jira, or GitHub and pass them with full context to agents.
• Remote SSH — Connect to remote machines over SSH and run agents on repos that aren't on your local machine.
• MCP Server Support — Connect tools through the Model Context Protocol without extra glue code.
• CLI Auto-Detection — Emdash automatically finds your installed agent CLIs — no setup checklist required.
• Built-in File Editor — Edit files and review diffs directly within the app without switching to another tool.
• Built-in Diff View — Review code changes, commit, and push without leaving the Emdash interface.
• 20+ Agent Support — Mix and match agents per task or stick with your favorite; Emdash works with Codex, Cursor, Amp, Claude Code, GitHub Copilot, and more.
