Emdash

What it does

Emdash is an open-source desktop environment for developers working with coding agents. Create tasks that run agents in separate Git worktrees, run several agents in parallel, and inspect their changes in a side-by-side diff view. You can review and iterate on work, then open a pull request from the app.

The app also schedules recurring agent runs, previews local or remote development servers in an in-app browser, and provides integrations for importing issues from services including Linear, Jira, GitHub, Notion, and Asana. Its reusable-resource library manages prompts, skills, and MCP servers; it also supports remote development over SSH and displays GitHub Actions checks.

Emdash is intended for developers coordinating agent-assisted software work. The current documentation describes a desktop app for macOS, Windows, and Linux. The site advertises a download and calls Emdash free and open source; it does not establish whether agents, model usage, or remote compute are included at no cost. The site also promotes Emdash 2.0 as early access via a waitlist, so that offer should not be conflated with the documented desktop product.

What it can do

• Run multiple coding agents simultaneously in separate Git worktrees
• Schedule recurring agent runs and review run history
• Preview local or remote development servers in an in-app browser
• Review changes across agents in a diff view and open pull requests
• Import issues from supported project and code-hosting services
• Manage reusable prompts, skills, and MCP servers

Works with

• Linear
• Jira
• GitHub
• Notion
• Asana
• GitHub Actions
• SSH

Before you choose

• The main site lists 25+ supported agents while the docs list 34 CLI-based agents; supported-provider counts may vary across page versions.
• The vendor information does not confirm whether agent/model usage, provider subscriptions, or remote infrastructure costs are included in the free, open-source app.
• Emdash 2.0 is separately presented as early access through a waitlist; its cloud-first positioning should not be assumed to describe the current desktop app.

Get started

The site offers a download; the docs link to an installation guide.

1. Download and install Emdash using the official installation guide.
2. Set up or connect a supported coding-agent CLI; the vendor information does not specify provider account or billing requirements.
3. Create a task to run an agent in its own worktree, then review the resulting changes in Emdash.

The desktop app is explicitly free and open source. Third-party coding-agent/model subscriptions and remote infrastructure may have separate charges; confirm those with the selected provider.
