Orca
Summary: Orca is an open-source Agent Development Environment for running and coordinating coding agents in isolated, reviewable workspaces.
At a glance​
| Question | Answer |
|---|---|
| What is it? | An Agent Development Environment |
| Main job | Coordinate parallel coding-agent work |
| Isolation | Git worktrees |
| Agents | Claude Code, Codex, OpenCode, and other CLI agents |
| Interfaces | Desktop, CLI, remote runtime, and mobile companion |
| License | MIT |
What it adds​
- Parallel worktrees for separate agent tasks
- Terminal splits and session management
- Diff review and line-level feedback
- Browser previews and design mode
- GitHub and Linear workflows
- SSH and remote worktrees
- Notifications and mobile monitoring
- CLI automation for Orca workflows
How it works​
repository
├── worktree A -> agent A -> task A
├── worktree B -> agent B -> task B
└── worktree C -> agent C -> task C
Orca launches or hosts CLI coding agents, gives each task an isolated worktree, and provides a place to monitor and review the resulting changes. Git still manages the worktrees and branches; Orca coordinates the surrounding agent workflow.
Manual workflow versus Orca​
| Manual approach | Orca approach |
|---|---|
| Create worktrees with Git commands | Create and track worktrees in one environment |
| Open separate terminals | Manage agent terminals and splits together |
| Check each branch separately | Compare sessions and diffs in one workspace |
| Coordinate follow-ups manually | Send feedback through the agent workspace |
| Manage remote sessions separately | Connect remote worktrees through Orca |
Orca does not remove the need to understand Git. It packages common parallel-agent operations into a coordinated interface.
What it is not​
- Not a language model
- Not a replacement for Claude Code, Codex, or OpenCode
- Not a Git replacement
- Not automatically a hosted VPS
- Not a guarantee that parallel results are correct
When it fits​
- Several agents should try different solutions to the same task.
- Tasks can be isolated into separate branches.
- Reviewing and comparing agent output is important.
- Agents need to run on another machine or continue while you are away.
For one small task with one agent, the agent's normal CLI may be simpler.
Remember​
- Orca coordinates agents; the agents perform the coding work.
- Git worktrees provide the isolation Orca builds on.
- The main value is parallel execution plus a review workflow.
