PatternFly

Checked 2026-10-22 against official website/docs/repository. MIT code verified in patternfly/patternfly and patternfly/patternfly-react. Install @patternfly/patternfly for the HTML/CSS foundation; patternfly.css includes base, component and layout styles while utility styles are separate. React projects use @patternfly/react-core and its base stylesheet; tables, charts and extensions have separate packages. Do not duplicate core CSS imports. Editorial: strong for dense enterprise consoles and consistent data-heavy workflows, less suited to decorative marketing-first interfaces. Vendor branding, fonts and third-party assets have separate rights; source accessibility guidance is not a certification. No paid core plan found. Source landing was captured at an actual 1440x2400 viewport to expose the full inner pane. Both inspected close controls dismissed update/cookie banners without opting into tracking. Native mobile pane has 15px horizontal overflow; this is a site defect, not a recommended pattern.
