Captain's Deck

Captain’s Deck provides a dual‑pane file manager for macOS, offering side‑by‑side panes for copying, moving, and comparing files. It integrates a terminal that follows the active directory, allowing users to switch between graphical navigation and command‑line operations without leaving the application. The manager supports remote connections such as SFTP, FTP, and S3, treating cloud and server locations like local folders.

Designed for power users, the interface emphasizes keyboard navigation with Vim‑style shortcuts and traditional arrow keys, enabling rapid browsing of large directories. Search combines Spotlight‑style metadata lookup with content‑based grep, and Git integration displays file status via color‑coded badges while permitting staging, committing, and diff viewing directly from the manager.

Implemented in Swift with a C++ core, the app runs natively on macOS 14+ using AppKit, employing lazy‑loading and asynchronous operations to handle directories containing millions of items while keeping memory usage low and UI responsiveness high.
