AeroSpace

AeroSpace provides a tiling window manager for macOS that follows the i3‑style tree paradigm. It arranges windows in a hierarchical layout, supports rapid workspace switching without animations, and implements its own virtual‑workspace emulation rather than relying on native macOS Spaces. The manager works with multiple monitors using the same i3‑like approach and does not require disabling System Integrity Protection.

The tool is configured through plain‑text TOML files, making it friendly for dotfile‑based setups, and includes a command‑line interface with manual pages and shell completion. Installation is offered via Homebrew, which also supplies automatic updates. AeroSpace is open‑source, free to use, and distributed without Apple notarization, removing quarantine warnings on launch.

It targets macOS power users who prefer keyboard‑driven, tiling workflows similar to i3 on Linux. Community interaction occurs through GitHub Discussions, where users can share configurations, report bugs, and propose enhancements.
