Mosaico

A cross-platform tiling window manager, written in Rust.

Mosaico automatically arranges your windows into a non-overlapping tiled layout using a Binary Space Partitioning (BSP) algorithm. It runs as a lightweight background daemon and is controlled entirely from the command line or via global keyboard shortcuts.

Features

• Automatic tiling – windows are arranged in a BSP layout the moment they open, close, or are moved between monitors.
• Vim-style navigation – focus and move windows with Alt + H/J/K/L.
• Workspaces – up to 8 independent workspaces per monitor.
• Multi-monitor – each monitor is managed independently with cross-monitor navigation.
• Focus borders – colored overlay border around the focused window.
• Monocle mode – full-screen single-window mode per monitor.
• Status bar – configurable per-monitor bar with workspace indicators, clock, CPU, RAM, and more.
• Catppuccin theming – built-in theme system with four flavors.
• Hot-reload – configuration changes are applied without restarting.
• Window rules – exclude specific applications from tiling.
