This week's donation went to the XFCE project. It's a lightweight desktop environment for UNIX-like operating systems that tries to be fast and use less system resources. XFCE uses the GTK engine. It currently uses Xorg but there is active work getting it to work with Wayland.
The main website for the project is here:
The source code can be found on Gitlab:
https://gitlab.xfce.org/explore/groups?sort=name_desc
The project has a presence on Mastodon:
xfce@ floss.social
If you want to help the project financially they accept donations through two Open Collectives. The only difference between the two is whether you want to donate using USD or Euros.
