About Emdash

Emdash is a free, open-source agentic development environment that lets you run coding agents in parallel, schedule repeat work, preview apps in a built-in browser, and manage prompts, skills, and MCP tools from one place. It’s built for developers who want to run multiple agents without lock-in, on macOS, Windows, and Linux.

Key Features

Coordinating multiple coding agents happens in a single workspace: you set up parallel tasks, track progress, and validate results as you go:

Parallel Agents

Run multiple agents in parallel, each with its own context, enabling simultaneous task execution.

Isolated Workspaces

Each task runs in its own Git worktree; separate branch, terminal, conversation, and review state.

In-App Browser Preview

Preview local and remote apps inside the built-in browser, with support for multiple browser profiles.

Remote Development via SSH

Run agents on any machine; connect over SSH and provision workspaces on demand.

Summary

Best for software engineering teams building AI copilots, R&D groups running agent-driven workflows, and DevOps/platform teams needing remote, isolated development environments.
