It owns the host-scoped dependencies needed to run provider ACP sessions, but it should not mix cross-session routing with per-session state projection.main-processThe main process is organized into domain modules under `src/main/core/`.

Emdash is a desktop app for running AI coding agents in parallel. Each task runs in its own Git worktree, so you can explore multiple fixes or features at once, review the diffs, and merge what works.
It works with local projects and remote machines over SSH. Bring the CLI agents you already use: Claude Code, Codex, OpenCode, Amp, and more.
What You Can Do
- Run multiple coding agents at once without juggling terminals.
- Keep every agent isolated in its own Git worktree and branch.
- Send issues and tickets from Linear, GitHub, Jira, GitLab, Asana, Featurebase, Monday.com, Forgejo, or Plain into an agent.
- Review diffs, create pull requests, inspect CI checks, and merge from one place.
- Work locally or on your own remote machines over SSH/SFTP.
Installation
| Platform | Install |
|---|---|
| macOS | brew install --cask emdash · Apple Silicon · Intel |
| Windows | Installer · Portable |
| Linux | AppImage · Debian package |
See the latest release for all desktop builds.
Agents
Emdash detects installed provider CLIs automatically. It supports agents like Claude Code, Codex, Cursor, OpenCode, Amp, Devin, Qwen Code, Droid, and GitHub Copilot.
See Providers for the full list, setup commands, and provider-specific behavior.
Remote Projects
Connect to remote machines with SSH/SFTP and run the same parallel workflow on remote codebases. Emdash supports SSH agent, key, and password authentication, with credentials stored in your OS keychain.
See Remote Projects and Bring Your Own Infrastructure for setup details.
Privacy
Emdash is local-first. App state is stored in a local SQLite database, and Emdash does not send your code or chats to Emdash servers.
Agent CLIs may send code, prompts, and context to their own providers. Their data handling depends on the provider you choose.
Telemetry is optional and can be disabled in Settings or by launching with:
TELEMETRY_ENABLED=false
See Telemetry for details.

FAQ
emdash is a Claude Code plugin with hand-picked skills for development work, indexed on Flowy. Install it with the command on its page. Its skills do not fire on their own yet. Request auto-invocation to have Flowy route them as you prompt. Free and open source.
- What is emdash?
- Emdash is the Open-Source Agentic Development Environment (🧡 YC W26). Run multiple coding agents in parallel. Use any provider.
- How do I install emdash?
- Run these in Claude Code: . Then prompt normally.
- Does emdash auto-invoke its skills?
- Not yet. It is indexed on Flowy as a plain plugin. Request auto-invocation on its page and Flowy will route its skills for you as you prompt.
- Is emdash free?
- Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.
