Open Source Rust Window Managers

komorebi is a tiling window manager that works as an extension to Microsoft's Desktop Window Manager in Windows 10 and above. komorebi allows you to control application windows, virtual workspaces and display monitors with a CLI which can be used with third-party software such as AutoHotKey to set user-defined keyboard shortcuts. komorebi aims to make as few modifications as possible to the operating system and desktop environment by default. Users are free to make such modifications in their own configuration files for komorebi, but these will remain opt-in and off by default for the foreseeable future.

Penrose is a modular library for configuring your own X11 window manager in Rust. This means that, unlike most other tiling window managers, Penrose is not a binary that you install on your system. Instead, you use it like a normal dependency in your own crate for writing your own window manager. Don't worry, the top-level API is well documented and a lot of things will work out of the box, and if you fancy digging deeper you'll find lots of opportunities to customize things to your liking. Penrose was born out of my failed attempts to refactor the dwm codebase into something that I could more easily understand and hack on. While I very much admire and aim for minimalism in code, I personally feel that it becomes a problem when your code base starts playing code golf to keep things short for the sake of it.

FlickOS 2.0 is a lightweight Linux desktop based on Debian 13 (trixie) with a labwc Wayland session. It ships as a live ISO with the Calamares installer. One hybrid ISO boots BIOS and UEFI and can be written to USB. 64-bit only. Three layouts switch live: Redmond (default, one bottom panel), Cupertino (top bar and dock), and Traditional (top panel and window list). Arc-Dark by default, with a Light desktop style. Optional tiling is off by default (Super+T). Installed systems get a graphical login; the live session logs in automatically. Includes Firefox ESR, LibreOffice, VLC, Bluetooth, printing, Flatpak, PipeWire and NetworkManager. Firewall on (incoming blocked), automatic security updates, and FlickOS desktop updates via apt. No in-place upgrade from FlickOS 1.x (Ubuntu 20.04 / LXLE). Back up and install 2.0 fresh.

Free and Open Source alternative to RocketDock and WinStep Nexus. Frutiger Aero glass dock and app launcher for Windows 10/11. Pinned apps, live window previews, cursor magnification, running-app indicators, and six themes. Built with Tauri and Rust. Lightweight, fully offline, no telemetry.

Left is a tiling window manager written in rust for stability and performance. The core of left is designed to do one thing and one thing well. Be a window manager. Because you probably want more than just a black screen LeftWM is built around the concept of theming. With themes, you can choose between different bars/compositors/backgrounds/colors, whatever makes you happy. LeftWM has been built from the very beginning to support multiple screens and has been built around ultrawide monitors. You will see this with the default key bindings.

This library encapsulates layout calculations from external dependencies and displays servers, so that it can be used by window managers for X.Org, Wayland, or whatever else. It's all about splitting up rectangles, the library has no concept of "windows". Some default layouts are provided, but custom layouts can be defined. Custom layout definitions allow some flexibility but are still fairly limited by design, as the target audience of this library is list-based / dynamic-tiling window managers (the likes of leftwm, dwm, ...) as opposed to manual tilers like i3.

Baru gathers the information from /sys and /proc filesystems (filled by the kernel). Except for audio and network modules that use C libraries. There is no memory leak over time. All modules are threaded. Thanks to this design (as well as Rust and C), baru is lightweight and efficient. It can run at a high refresh rate with a minimal processor footprint. The audio module communicates with the PipeWire/PulseAudio server through client API to retrieve its data. Wireless and wired modules use the netlink interface with the help of libnl to talk directly to the kernel and retrieve their data. Baru is modular. This means that only the modules you want to see are instantiated and executed.

Wira Desk is a lightweight suite of desktop tools for Windows. It runs as an elevated system-tray daemon with a global low-level keyboard hook, enabling same-app window switching (cycling between windows of the currently focused app) and fast one-key window snapping and arranging -- halves, thirds, or a custom percentage per edge -- each shortcut configurable and toggleable on its own. A companion Settings app lets you view and change those shortcuts. The installer requires Administrator and installs to %ProgramFiles%, a deliberate choice: auto-start runs the daemon elevated at every logon with no prompt, so only an admin-writable directory protects that path. Auto-start is off by default; enable it yourself from the tray menu or Settings. Wira Desk is free and open source under the GPL-3.0-only license. The Settings window is built with Slint (https://slint.dev), used under its GPL-3.0-only license too. By Wira Digital Indonesia.

SnapToWindow is a user-experience utility likely aimed at enhancing window management on desktop environments by enabling users to “snap” application windows into predefined screen positions or layouts using keyboard shortcuts or mouse gestures. These kinds of tools are popular for improving productivity, especially on multi-monitor setups, by letting users quickly align and resize windows to halves, quarters, or other grid arrangements without manual dragging. While official project documentation isn’t available from search, the repository name and conventions imply a small, focused tool that hooks into the native windowing system (on Windows, macOS, or Linux) to detect active windows and reposition them based on user commands. It helps streamline workflows for developers, designers, and multitaskers who juggle many open windows and want consistent, repeatable layouts.

This tool allows you to rapidly choose a specific window directly without having to use the mouse or directional keyboard navigation. Thanks to cairo, it should work on all kinds of screens and automatically display at the correct size according to your DPI.
