A component framework with typed messages, GTK4- and libadwaita-class widgets, a modern component set, a GTK-flavoured CSS engine, and an event loop that idles at 0% CPU. No cgo.

Components

A relm4-style framework. Each component is a model with typed input and output messages, built with typed view builders.

Modern components

Accordions to sidebars, data tables to date pickers, in a dark and a light palette, restyled by an application stylesheet.

The desktop

xdg-shell and layer-shell windows, session lock, portals, clipboard, drag and drop, screen capture and AT-SPI accessibility.

Tested on real compositors

The compositor-in-the-loop suite runs on a private headless sway and on Hyprland in a NixOS VM, and both are required CI gates.
