Orca

Orca runs several coding agents at once, each in its own isolated git worktree, and gives you a single view of the fleet. It drives the CLI agents you already use — Claude Code, Codex, Gemini and others — from a desktop application, with a mobile companion for checking on work in progress.

The worktree isolation is the part that makes the rest possible, and it is worth understanding why. Two agents editing the same checkout will corrupt each other's work in ways that look like model unreliability: a file changes under an agent mid-task, tests fail for reasons that no longer exist, and the diff that comes back is not the change that was requested. Isolating each agent in its own worktree removes the interference and moves the hard problem to the join — several branches to review and reconcile, possibly touching the same code. So parallelism converts a coordination problem inside one task into a merge problem across several, which is usually the better trade but not a free one.
