Red Hat PatternFly
The Red Hat renderer is built on PatternFly 6 (@patternfly/patternfly) — a global CSS framework of pf-v6-c-* classes and design tokens, applied to Mateu’s own light-DOM markup. It is a good choice when your team favors the Red Hat ecosystem or when the UI needs to blend into an existing PatternFly application.
