Built on wlroots, it handles the Wayland protocol including virtual input/output devices. Version 1.0 introduces native rendering via dmabufs and GdkTexture integration (eliminating extra buffer copies), a GtkScrollable interface, and a simple API for spawning or connecting client processes. GObject introspection enables bindings for Python and JavaScript. The library was originally created for Cambalache, a GTK GUI designer, to preview widgets in isolated processes. ## Full article daily.dev links to this article rather than hosting it.
