Visit websiteWhat is Emdash?
Emdash is an open-source desktop application that lets developers orchestrate multiple coding agents simultaneously, each isolated in its own Git worktree. Part of YC W2026, it was founded by Raban von Spiegel (previously founded Soff, YC S24) and Arne Strickmann. The project has gained strong traction with 2,900+ GitHub stars, 220,000+ downloads, and 268 forks.
The platform supports 23+ agent CLIs including Claude Code, Codex, Gemini, Amp, Droid, and GitHub Copilot, making it fully provider-agnostic. Tasks start in 500-1000ms thanks to a pre-maintained reserve of worktrees. The workflow integrates directly with issue trackers (Linear, Jira, GitHub, GitLab) — developers can pass tickets to agents, review diffs in the built-in diff viewer, run CI/CD checks, create PRs, and merge, all without leaving the app.
A Kanban-style status board provides visual oversight of all running agents, and the "Best of N" feature lets you run identical tasks across multiple agents and compare results. For remote development, Emdash supports SSH/SFTP connectivity with secure credential storage. Built with Electron and TypeScript, it runs on macOS, Windows, and Linux and is installable via Homebrew.
