- Wayland is intended as a simpler replacement for X, easier to develop and maintain. GNOME and KDE are expected to be ported to it. Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers.
Part of the Wayland project is also the Weston reference implementation of a Wayland compositor. Weston can run as an X client or under Linux KMS and ships with a few demo clients. The Weston compositor is a minimal and fast compositor and is suitable for many embedded and mobile use cases.
- https://en.wikipedia.org/wiki/Wayland_(display_server_protocol) - a computer protocol that specifies the communication between a display server and its clients, as well as a reference implementation of the protocol in the C programming language. A display server using the Wayland protocol is called a Wayland compositor.Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open community-driven project with the aim of replacing the X Window System with a modern, simpler windowing system in Linux and other Unix-like operating systems.

- https://github.com/djpohly/dwl - a compact, hackable compositor for Wayland based on wlroots. It is intended to fill the same space in the Wayland world that dwm does in X11, primarily in terms of philosophy, and secondarily in terms of functionality

- https://github.com/taiwins/taiwins - a wayland window manager, supports both tiling and floating layout. It is designed to be mordern and modular. It is extensible through lua script and it has built-in shell and widgets implementation through nuklear GUI. It also supports popular tiling window manager features like gapping.
- https://github.com/ifreund/river - a dynamic tiling wayland compositor that takes inspiration from dwm and bspwm. Zig.
- https://github.com/stumpwm/mahogany - a tiling window manager for Wayland modeled after StumpWM. While it is not a drop-in replacement for stumpwm, stumpwm users should be very comfortable with Mahogany
- https://github.com/Cloudef/orbment - modular compositor for Wayland with flexible plugin architecture where plugins may co-operate with each other. The core consist of small code base which provide plugin management, and hooks api for plugins. Core plugins are used to provide functionality you would expect from bare bones tiling window manager.
- https://github.com/buffet/kiwmi - a work-in-progress extensive user-configurable Wayland Compositor. kiwmi specifically does not enforce any logic, allowing for the creation of Lua-scripted behaviors, making arduous tasks such as modal window management become a breeze. New users should be aware of the steep learning curve present, however this will be reduced as the project matures.

- Cage - a kiosk compositor for Wayland. A kiosk is a window manager (in the X11 world) or compositor (in the Wayland world) that is designed for a user experience wherein user interaction and activities outside the scope of the running application are prevented. That is, a kiosk compositor displays a single maximized application at a time and prevents the user from interacting with anything but this application.

- https://github.com/waymonad/waymonad - We all love tiling window managers and most of all we love xmonad. As you may know, wayland is trying to replace X11. This brings problems for us, since xmonad will not work with the new architecture. This project is intended to provide a wayland based desktop which shares the ideals and experience from xmonad.
