Its unique feature of running agents side-by-side in tabs and panes, along with built-in source control and GitHub integration, differs through the market.

Source: Official README and linked documentationThe architecture of Orca suggests a modular design with clear separation of concerns. It use TypeScript as the primary language and employs various design patterns such as MVC for the web interface and CLI. The code tree is structured into directories for different components, indicating a well-defined module decomposition. Data flow is managed through a series of scripts and workflows, with key technical decisions evident in the use of Electron for the desktop application and Vite for the web interface.

Sandcastle better fits centrally hosted server tasks. Orca offers a more direct path for a local graphical workspace around existing CLI agents.
