FAST works without tools as well: https://www.fast.design/docs/fast-element/defining-elements https://www.fast.design/docs/fast-element/defining-elements FAST is kind of like a Lit-clone (though it patches global prototypes) plus a design system base. There are lots of design systems built with Lit that you can chose from instead of us including our own: Shoelace, Adobe Spectrum, Redhat Patternfly, IBM Carbon, Material Web Components and more.
