About Orca
Orca is an agent desktop environment (ADE) that runs multiple AI coding agents in parallel, each in its own isolated git worktree. It unifies workflow, monitoring, and collaboration around AI assisted coding across desktop, mobile, and remote runtimes. Built for developers who rely on several AI coding tools simultaneously, Orca eliminates context switching by tracking all agents and their outputs in one place.
About Emdash
Emdash is an open source desktop app and agentic development environment for developers who want to run several AI coding agents in parallel, each isolated in its own Git worktree, against local projects or remote machines over SSH.
