Rectangle is a desktop window manager that organizes open application windows into predefined layouts and grid positions. It functions as a background utility, allowing users to manipulate window frames through keyboard shortcuts or mouse gestures to improve multitasking and workspace efficiency.
The application acts as a native interface extension, providing window snapping and tiling functionality that integrates directly with the operating system. It supports multi-monitor setups, enabling the distribution and alignment of windows across various displays. By utilizing the system accessibility framework, the tool programmatically queries and modifies window geometry to ensure precise placement.
The software manages window arrangements by intercepting global hotkeys and mouse events to trigger layout logic. It continuously monitors display configurations to adjust snapping boundaries dynamically, calculating target window positions based on screen dimensions and user-defined constraints.
