A little more room to think

A place for every window.

Tessera tiles every Mac window the moment it opens, and closes the gap when one goes away. No dragging, no snapping, no config files.

Every window gets a place

Pick a layout once. Tessera keeps it true as you work.

Opens into place
A new window takes the next free tile. Windows already open shift to make room.
Stacks when full
Past four windows, new ones stack on the tile you’re working in instead of shrinking everything.
Closes ranks
Close a window and the rest grow back into the space.
Four layouts
Grid, Columns, Rows and Side. The main window takes a half, 60% or two-thirds.
Every display
Each screen keeps its own layout. Side holds five on an ultrawide and puts the main window on top of a vertical monitor.
Knows when to stay out
Dialogs, sheets and panels are never tiled. Turn tiling off per app from the menu bar. Tessera steps aside while Stage Manager is on.

Everything works from the keyboard. Nothing to configure.

⌃⌥⌘1–4
Grid, Columns, Rows, Side.
⌃⌥Z
Focus: one window fills the screen. Press again to put it back.
⌃⌥←↑↓→
Swap with the neighbouring window. Past the screen edge, move it to the next display.
⌃⌥⌘P
Pause. Windows stay exactly where they are.
Drag
Drop a window onto another tile to swap the two.

About a minute, start to finish.

Open the disk image and drag Tessera to Applications.

Allow Accessibility when asked. Tessera now lives in the menu bar.

This build is signed with a Developer ID; Apple’s notarization is on its way. Until then macOS asks you to approve Tessera once, and never again.

Window positions. Nothing inside them.

Accessibility
macOS requires this permission for any app that moves another app’s windows. Tessera reads each window’s position, size and owning app, and nothing else.
No peeking
It never reads window contents or titles and never takes screenshots.
No network
The app makes no network connections at all. No accounts, no tracking. This website counts anonymous page views, without cookies.

Make space for what matters.
