Emdash — Coding Agents Platform
Founded 2025|San Francisco, CA|2-10 people|Open Source
What 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.

Strengths and tradeoffs
What this tool does well, and the limitations to keep in mind.
Pros
- Fully open source (MIT) with zero cost and no vendor lock-in — 2,900+ stars and 220K+ downloads
- True multi-agent parallelism with Git worktree isolation preventing conflicts between agents
- Provider agnostic supporting 23+ coding agent CLIs from all major providers
- End-to-end workflow from issue tracker to PR merge including diff review and CI/CD checks
- Remote SSH support enabling use with cloud dev environments and powerful remote hardware
Cons
- No built-in AI — requires separate paid subscriptions for each coding agent CLI
- Electron-based and can be resource-heavy when running 20+ agents concurrently
- Enterprise features like team management and auth are planned but not yet shipped
- Early-stage desktop app at v0.4.x — users may encounter stability issues

Common use cases
Developers using multiple coding agents
- Parallel coding tasks
- Multi-agent orchestration
- Remote development
- Large codebase refactoring
Using Emdash with Respan
Emdash orchestrates multiple coding agents, each making LLM calls. Respan can monitor the aggregate LLM usage across all agents running in Emdash, providing cost visibility and performance tracking for multi-agent development workflows.
- Track total LLM costs across all coding agents orchestrated through Emdash
- Monitor agent performance and compare output quality across different providers
- Optimize multi-agent workflows by identifying cost and latency patterns via Respan
