Tessel gives every window on your Mac its own place on the screen. Drag one to an edge or onto another, and the rest make room. Close or minimize one, and the others fill the gap.

What it does
Tessel works with the windows you already have. It never asks you to learn a grid or memorize a layout language. You move a window where you want it, and Tessel keeps the rest in order.
Minimize or close a window and its neighbors grow into the space at once. Bring it back from the Dock and it gets its own place again.
A window you open later takes a share of the biggest space.
Window Map. Press ⌃⌥W for a map of every window as it is tiled, including hidden tabs and minimized windows. Click one to bring it forward. It is optional: turn it on from the menu.
Build app groups. Keep the apps you use together in one tab bar, say Mail, Calendar and Notes. Press ⌃⌥⇧ and a number to save the layout, and ⌃⌥ with the same number brings your groups back.
When a window can't shrink to fit, Tessel adds it as a tab where it fits, and takes it back out when room frees up.
Drag the gap between two windows, or a window's own edge, and both sides resize together. If a neighbor would end up smaller than its app allows, it moves into a tab where it fits.
Tap three fingers on the trackpad, or press ⌥⌘P, to pin a live view of a window above everything else. Pin several at once. Press and hold three fingers, or press ⌥⌘F, to lock focus on one app while you work. No trackpad needed.
Every macOS desktop keeps its own arrangement. Switch desktops and each one comes back exactly as you left it.
Press ⌃⌥⇧ and a number to save how your windows are arranged. ⌃⌥ and the same number puts them back, even after the apps have restarted.
One menu item returns every window to where it was before, and you have a normal Mac again. Choose Set Windows to tile them again.

Accessibility lets Tessel move and resize your windows. Screen Recording is optional and shows live pinned windows and pictures of small panes.
No account and no cloud sync. Window previews are processed on your Mac. Settings, layouts and diagnostic details are stored locally. Read the Privacy Policy.
