Open Source Rust Wayland Compositors

Niri is a dynamic, scrollable-tiling Wayland compositor built for Linux composed around columns laid out infinitely to the right. It supports multi-monitor setups, fractional scaling, floating windows, NVIDIA drivers, and input devices like tablets and touchpads. Stable for daily usage, many users have adopted it as their primary Wayland environment.

Fireplace is a lightweight, modular Wayland tiling window manager written in Rust. Built on Smithay or wlc (in older code), it supports floating windows, BSP-style tiling, layer-shell basics, and workspace concepts. It aims to serve as a rapid-development playground for rich, keyboard-driven desktop workflows with GNOME compatibility goals.

Smithay is a modular toolkit for building Wayland compositors in Rust. Rather than a standalone compositor, it provides building blocks like protocol handlers, session backends, DRM abstractions, and input/output utilities. It supports core and extended Wayland protocols, libseat, tablets, graphics tablets, Xwayland, and more. It's mature and under active development, providing a “smithy” for compositor authors.
