AltSnap

AltSnap is a free, open-source window management utility for Windows, developed as a maintained continuation of AltDrag. It allows users to move and resize application windows by holding the Alt key and clicking anywhere inside them. This approach eliminates the need to precisely target title bars or window borders. The software provides window snapping, transparent dragging, and customizable mouse actions for efficient desktop organization. Users can configure keyboard shortcuts, window behavior, and application-specific exclusions. AltSnap also includes options for maximizing windows and adjusting process behavior. Designed for a wide range of Windows versions, it operates without injecting DLLs into other applications, providing lightweight and flexible window management.
