About Emdash
Summary
Emdash builds an open-source, provider-agnostic desktop application for engineering teams that want to run multiple coding agents in parallel. Teams can execute concurrent tasks across isolated Git worktrees, pull issues directly from Linear, Jira, GitHub, and other trackers, and manage prompts, skills, and tools from a single interface. It replaces the manual, sequential workflow of switching between agents, terminals, and context windows.
Go-to-market
Engineering teams at software companies are the buyers; the app is available as a direct download on macOS, Windows, and Linux, with a self-serve model supported by a free open-source tier and Cloud and Enterprise plans.
