StreamWindow

StreamWindow provides a three‑dimensional interface for arranging application windows on macOS. It presents windows as a 3D stack that can be navigated with Cover Flow‑style animations, allowing users to preview multiple windows simultaneously and switch between them using fluid transitions. The tool supports customizable hotkeys for common actions such as moving, resizing, and snapping windows, and it integrates with multi‑monitor setups to manage windows across several displays.

Designed for macOS 14 and later, StreamWindow replaces traditional flat window‑management utilities by offering a visual, spatial view of open applications. Users can drag windows into the 3D space, rotate the view, and select a window to bring it to the foreground, all while preserving the underlying macOS window‑management behavior. The application is distributed as a free download and is positioned as an alternative to existing tiling or snapping tools.
