TrellisWM

TrellisWM is a native window management tool for Apple chip Macs.

Running on macOS 14 Sonoma and later. It reorganizes real application windows through nested spaces and a scalable desktop view. Users can drag windows to other windows or the edge of the screen for docking, zoom between multiple levels of spaces, and quickly view all windows, go to the parent space, focus on the current window, and switch between adjacent areas using trackpad gestures or keyboard shortcuts. The software supports dragging separator lines to adjust window size synchronously, and when a window is minimized, it is automatically filled by neighboring windows. When restored, it returns to its original position, and the layout can be saved for each monitor. TrellisWM The professional version offers unlimited dockable windows, cross-application tab groups, saved views, URL commands, and support for future Windows versions; the free version retains core features such as docking, nesting, scaling, live preview, and keyboard navigation. TrellisWM is always present in the menu bar, supports restoring layouts, forward and backward navigation, and one-click return to the normal desktop. It is built with Swift, AppKit, Accessibility, and ScreenCaptureKit, and screen recording permissions are optional. Window previews are from static images and are not recorded or saved.
