Since a while I thought about having a website similar to crates.io or pypi.org, but for GObject libraries. At the moment you always need to search on the internet for such libraries and not so popular ones are really difficult to find. Especially for languages that are mainly enabled by GObject, but also for example in other languages to integrate better with other already used GObject libraries like GTK.
So I made now a prototype. You can search for gtk and libsoup just to demonstrate how it would work. I would like to have something like that maybe on developer.gnome.org, but a dynamic search is as far as I know not possible there. Also many libraries would go there which are not part of the gnome platform and therefore wouldn’t fit into the platform overview page there.
