Copperbar keeps coding agents in separate worktrees—and the merge in human hands
A Mac app for running Claude Code, Codex, Cursor, and OpenCode in separate Git worktrees, with tools for reviewing changes before accepting them.
- For
- Mac developers running multiple coding agents
- Worth noticing
- Bounded goals set attempt limits and a start deadline; the page says agents wait for explicit acceptance.
Field notes
The illustrated demo uses a project called Trailhead and shows separate tasks for improving search, exploring navigation, and reviewing accessibility. The page also describes bounded goals with attempt limits and a start deadline, and an optional phone view for following along while the Mac runs. Copperbar says workspace data and session logs stay on the Mac by default, while agent providers receive context sent by their CLIs. The app is identified as a beta, with public downloads unavailable.
