# Emacs as a Window Manager and concurrency
Thomas Koch - <https://blog.koch.ro>, <mailto:thomas@koch.ro>

[[!inline pages="internal(2026/info/rau-before)" raw="yes"]]

Rau is one of three different Wayland Window Manager projects active right now
and the only one written only in Elisp (at the moment).

I'll present the current state of Rau, compare it with the other two projects
(Reka, EWM) and discuss some difficulties encountered with a focus on
concurrency and Emacs.

Rau is already fully functional for daily use. The single threaded nature of
Emacs however is a major issue that will require to move the major part of Rau
from Elisp into an Emacs module and thus into another language.
