SnapToWindow – A cross-platform window manager
On macOS, Rectangle handled window snapping beautifully. On Windows, the built-in snap works but the shortcuts are different. I wanted one tool with one set of keyboard shortcuts that worked the same on both platforms.
So I built SnapToWindow.
What It Does
SnapToWindow snaps windows to halves, quarters, thirds, and more using keyboard shortcuts. Ctrl+Alt+Left on Windows, Control+Option+Left on macOS—same logic, same muscle memory.
It runs quietly in your system tray. Fifteen positions total, each one keystroke away. Multi-monitor support is built in.
Open Source
SnapToWindow is fully open source on GitHub, dual-licensed under MIT and Apache 2.0. A window manager has access to your screen layout and active windows—you should be able to verify exactly what it does.
The codebase is cleanly structured. Rust backend in src-tauri/, window management logic split by platform (windows.rs, macos.rs, and a stub for linux.rs). Contributions are welcome, especially for Linux support.
Your windows. Your shortcuts. Every platform.
