Way Cooler is a tiling Wayland window manager, written in Rust, configurable using Lua, and extendable with D-Bus.

Extendable

Way Cooler gives the user full control in extending the capabilities of the window manager, without having to write a single line of Rust. Core functionality is implemented as D-Bus clients, allowing programs such as the lock screen and status bar to be implemented in any language that can speak the D-Bus protocol.

Consult our D-Bus documentation for more details

Configurable

Lua is a first class citizen of Way Cooler. Tiling options, window rules, and theme options are controlled by the integrated Lua thread. Short scripts, that are otherwise too short to be proper client programs, can also be written to extend the capabilities of the window manager.

Secure

Way Cooler is designed from the ground up to be secure. Rust prevents Way Cooler from ever having a data race, dangling pointers, or a segfault. Large classes of security vulnerabilities, such as from buffer overruns or use after free, are a thing of the past.

In order to maximize the security guarantees of Wayland, all client programs must first be authenticated using Lua, and are only granted the permissions they require in order to do their task. Applications can no longer read your keystrokes unless you give them explicit permission to do so.
