Emdash

Emdash is an open-source agentic development environment to run coding agents in parallel and review changes.

Emdash is an open-source agentic development environment that lets developers run multiple coding agents in parallel, schedule recurring work, and review changes in one place. It integrates with issue trackers like Linear, Jira, GitHub, Notion, and Asana to pass issues directly to agents with full context. Users can run agents such as Codex, Cursor, Claude Code, Amp, and Antigravity, or use any provider without lock-in. Workspaces operate in isolated Git worktrees where each keeps its branch, terminal, conversation, and review state. Developers can preview apps in a built-in browser, inspect diffs, create pull requests, and monitor continuous integration checks directly within tasks. The platform runs on macOS, Windows, and Linux, and supports remote execution over SSH on dev servers, cloud virtual machines, or GPU boxes.
