Free
The desktop application and mobile companion are free and open-source under the MIT License. Users are responsible for the costs of the individual agent subscriptions or API keys they choose to run within the environment.
Best for
Solo developers and platform teams who need to run multiple AI coding agents in parallel and require a centralized cockpit for orchestration, diff annotation, and multi-model comparison.
Not ideal for
Users who require a durable, shared task record for team collaboration, or those who prefer a single-agent, all-in-one IDE experience without the overhead of managing multiple worktrees and API subscriptions.
Orca is a powerful, high-velocity orchestration tool that effectively solves the throughput bottleneck of single-agent development, making it an essential utility for power users who want to leverage multiple AI models simultaneously.
Recent releases (v1.4.180–v1.4.188) introduced stacked GitHub pull requests, cross-computer session search, OpenCode 2 support, collapsible diff regions, and improved reliability for remote/SSH workspaces and terminal pane restoration.
