Emdash 1.2.10 for Mac
Mac UtilitiesEmdash is a desktop app for developers who work with AI coding agents. Instead of juggling several terminal windows, you create tasks inside Emdash and it runs agents in parallel for you. Each task gets its own Git branch and worktree by default, so multiple agents can change the same repository at once without stepping on each other. You review the differences each agent produces and merge only the work you like. It is free, open source under the Apache 2.0 licence, and keeps your code on your own machine.
Key Features
- Parallel agents: run many coding agents at the same time in one calm workspace
- Worktree per task: every task works in its own Git worktree and branch
- Wide agent support: works with popular agents such as Claude Code, Codex and GitHub Copilot
- Local first design: app state lives in a local database and code is not sent to Emdash servers
- Review tools: inspect changes, view diffs and use the in app browser inside each task
- Remote work: connect to other machines over SSH and run tasks there
