Native macOS app · Sidebar-first workflow
Mac window manager for people who actually work with many windows.
WindowShelf gives you a persistent sidebar for switching windows, grouping related work into custom shelves, arranging layouts, and staying oriented across apps, Spaces, and multiple displays.

SidebarAlways-visible or edge-revealed window control
ShelvesGroup windows by project, not only by app
TilingHalves, corners, center, maximize, and category layouts
DisplaysWorks on the primary display or the screen under your cursor
One clear view of your Mac workspace.
Most Mac window tools specialize in only one thing. WindowShelf combines visibility, switching, organization, and layout control in one native sidebar.
Group work by project with custom shelves
Put related windows from different apps into one named shelf, reorder them, and come back to the same structure later.
Arrange windows without covering the sidebar
Tile windows to halves, corners, center, or maximize them with layouts that respect the sidebar width.
Why WindowShelf fits a different workflow than Stage Manager or shortcut-only tools
Stage Manager is built around recent-app strips and grouped windows in the middle of the screen. Shortcut tools are built around moving and resizing. WindowShelf is built around maintaining a live, readable overview of your actual workspace.
- Always-visible sidebar instead of a hidden strip
- Custom shelves for cross-app work, not just app-based grouping
- Window switching, minimizing, restoring, and tiling in one place
- Multi-monitor awareness without turning into a heavyweight tiling system
- Native Mac styling with menu bar footprint and no Electron overhead

Frequently asked questions
Short answers for users comparing Mac window managers, Stage Manager alternatives, and sidebar-style workflows.
Is WindowShelf a full tiling window manager?
No. WindowShelf is better described as a sidebar-first Mac window manager. It includes useful tiling actions, but its main strength is visibility, grouping, and day-to-day window control.
Who benefits most from it?
People who keep many windows open: developers, designers, researchers, writers, operators, and anyone who jumps between apps all day.
Why use a sidebar instead of only shortcuts?
A visible sidebar reduces memory load. You do not need to remember every shortcut or keep guessing which windows are still open.
Does it work with project-based workflows?
Yes. Custom shelves let you collect windows from different apps into one named group, which is especially useful for launches, reviews, research, and client work.
