01
Choose window
Hover over the green window button and pick Peakr, or just drag the window to an enabled edge.
Built for macOS
Always have that one window close by.
Peakr tucks one app window against the edge of your screen, then hides it away until you actually need it.
Works on macOS 14+ · Needs Accessibility access

Three simple moves
Stay in flow. Just move the window.
Peakr only touches the one window you pick. Everything else on your desktop stays exactly where it was.
02
Dock it
It snaps into a full-height panel. Grab the inside edge to resize it.
03
Shelve it
Click away, move your pointer off, or hit the shortcut. Peakr slides out of sight and waits at the edge.
Built around edges
A few simple rules. A lot more space.
Left or right
Pick whichever edge feels natural, left, right, or both.
Full-height panel
Fills the screen from the menu bar down to the Dock.
Quick shelf
A slim little arrow handle brings it right back with a hover.
Two ways in
Drag to the edge and pause, or use the green window button. Whatever's faster.
Keyboard ready
Hit Control–Option–S to shelve or bring back whatever's docked.
Safe restore
Puts the window right back where it was, exactly as you left it.
Shelf behavior
There when you need it. Gone when you don't.
Peakr can tuck itself away the moment you click elsewhere or move your mouse off the panel. Not a fan? Turn that off in Settings.
Respects Reduce Motion, or switch on instant transitions if you'd rather skip the animation.

What to expect
Peakr moves and resizes the one window you pick, and remembers exactly where it was so it can put it right back.
It plays best with apps and windows built on standard macOS Accessibility.
