Questions

Is it really free? Will it stay free?

Yes. Orthant is free and open source under the MIT licence, and everything it does today stays free. That is a commitment, not a launch offer. There is no trial, no upgrade prompt, and no feature waiting behind a paywall.

Why does it need Accessibility permission?

Orthant uses the macOS Accessibility API to move and resize other apps' windows. Enable it in System Settings ▸ Privacy & Security ▸ Accessibility. First launch walks you through this step.

Why isn't it on the Mac App Store?

Orthant is distributed directly, with its own updater. Its window-control code runs outside the App Sandbox.

Each release is signed with an Apple Developer ID and notarized by Apple. Install it with Homebrew or download the disk image.

Does it conflict with macOS tiling, Rectangle, or Moom?

Orthant acts on the shortcuts you give it and can run alongside macOS's built-in tiling or another window manager. If two apps want the same combination, rebind one of them. Orthant's Shortcuts pane tells you when macOS itself has already claimed a chord.

Windows? Linux?

Windows support is planned. Linux is not supported.

How do updates work?

Orthant updates itself in place, verifying each update's signature before applying it. Your permission, shortcuts and regions are untouched. If you installed with Homebrew, brew upgrade deliberately skips Orthant rather than fighting the built-in updater. See Updates.

How do I get help?

Start with Troubleshooting. If that does not help, open an issue.
