Shoelace has matured into Web Awesome and has a whole team behind it, as well as an attractive pro offering. Quiet is my creative outlet. Some components from Quiet have been adapted to Web Awesome, but many probably don't make sense to such as joystick, mesh gradient, stamp, etc.

The theming layers are completely different. Web Awesome's theming system is more robust, with over a dozen pro themes already available with interchangeable, professionally-curated palettes. In contrast, Quiet has just one theme with a palette that's generated with color-mix().
