Complete Desktop Customization Suite
A fully customizable Windows 11 environment built on Rust + Tauri. Replace your taskbar, tile your windows, set live wallpapers, and add powerful desktop widgets — all in one free app.

Live Wallpapers & Animated Backgrounds
Go beyond static images. Play MP4 video files, interactive HTML/CSS/JS canvases, and music-synced backgrounds as live wallpapers. Set different wallpapers per monitor and per virtual desktop.
- Video wallpapers (MP4, WebM) with speed control
- Interactive HTML wallpapers with full Web API access
- Per-monitor and per-workspace wallpaper collections
- Blur, saturation, and color overlay controls

Automatic Tiling Window Manager
Stop resizing windows manually. Seelen UI tiles every window automatically using BSPWM, Tall, Wide, or Grid layouts — fully keyboard-driven, with float and monocle modes when you need them.
- 4 layout engines: BSPWM, Tall, Wide, Grid
- Navigate and move windows with Alt+I/K/J/L
- Float, stack, or monocle any window on demand
- Per-app rules: auto-float, auto-assign to workspaces

Dock, Toolbar & Start Menu
Replace the default Windows shell with something far more powerful. A smart dock with auto-hide and window previews, a fully scriptable live status bar, and a faster, more organized start menu.
- SeelenWeg dock — top, bottom, left, or right position
- Fancy Toolbar — live CPU, RAM, network, battery stats
- Smart start menu with apps, files, and web search
- Custom Alt+Tab switcher with live window thumbnails

Clock, Media & System Widgets
Bring useful information to your desktop. Media player controls, a live desktop clock, CPU and RAM monitoring, notification center, Wi-Fi, Bluetooth, and more — all as elegant, lightweight widgets.
- Media controls with album art and per-app volume
- Desktop clock, calendar popup, and timezone support
- System monitor: CPU per-core, RAM, network, disk
- Notification center with Do Not Disturb toggle

Everything Your Windows Desktop is Missing
