What is AeroSpace?

AeroSpace is a free, open-source tiling window manager for macOS modeled on i3. It arranges windows in a tree of tiled or accordion containers and replaces macOS Spaces with its own workspaces, which switch without animation. It is configured in a plain-text TOML file, driven by keyboard bindings and a command-line client, and is aimed at advanced users and developers.

AeroSpace is free to use. See every plan

Good for

  • Developers and advanced users who want i3-style tiling on a Mac
  • Keyboard-driven work with configuration kept in dotfiles
  • Multi-monitor setups that assign workspaces to particular displays

Worth knowing

  • macOS only: the released binary runs on macOS 13 or later.
  • Still a public beta; the README says to expect breaking changes until version 1.0.
  • There is no settings window. Configuration is a TOML text file, and the project says it will never add a GUI for it.
  • The app is not notarized by Apple, so a manual install can show a macOS security warning; the Homebrew install avoids it.

Key features

Tree-based tiling
Each workspace holds its windows in a tree of containers, a model taken from i3. Focus moves in four directions, and the move and join-with commands reshape the tree.
Tiles and accordion layouts
Four layouts: horizontal and vertical tiles, plus horizontal and vertical accordions that stack windows and leave a padded edge to show the others.
Emulated workspaces
AeroSpace uses its own workspaces instead of macOS Spaces, moving inactive windows off screen so switching has no animation. It does not need System Integrity Protection disabled.
Plain-text configuration
Settings and key bindings live in a TOML file such as ~/.aerospace.toml. Binding modes swap in a different set of shortcuts, as in i3.
Command-line client
The aerospace CLI runs the same commands as key bindings and can query state. Man pages and bash, fish and zsh completion are included.
Callbacks and monitor assignment
An on-window-detected callback runs commands for each new window, for example to send an app to a set workspace. Workspaces can be assigned to particular monitors.
