WindowManager helps you to improve your workflow by remembering and restoring the position and size of your programs and windows. Many programs don't remember their position and size between sessions and even Windows Explorer does not restore Windows to their last position under Windows 7 or higher. This is where WindowManager steps in and makes sure your windows are placed exactly where you want them every time you open them. WindowManager even allows you to lock the position and size of any window, so that it will always open at the same spot no matter where you move it. The window handling is fully customizable and you can set up special rules for your favorite or most frequently used windows. You can also make WindowManager send keystrokes or mouse clicks to a program when its window is opened, run additional programs, and other advanced actions. With WindowManager, you can also minimize most windows in the system tray.

SnapToWindow is a cross-platform, keyboard-driven window management utility that lets you quickly and precisely arrange application windows to predefined positions using customizable hotkeys so you can organize your workspace without touching the mouse. It works consistently on both Windows and macOS, supports multi-monitor setups, and runs quietly from the system tray with minimal resource usage, automatically updating in the background. Built with Rust, Tauri, and TypeScript for native-class performance and a small footprint, it offers global keyboard shortcuts (e.g., Ctrl + Alt on Windows and Control + Option on macOS) for snapping windows to regions like left/right halves, top/bottom halves, thirds, and center, as well as maximizing windows, giving you full control of your layout with a few keystrokes.
