Red Hat's open-source system for enterprise and infrastructure products. Built for dense, data-heavy operational interfaces.
Why we like it
PatternFly is the reference we reach for when the interface is operational and data-heavy, and its accessibility process is about as rigorous as any we've seen documented in public. It targets WCAG 2.2 AA, gates every component through an automated axe audit before it's accepted, and runs each one through VoiceOver by hand, with NVDA and JAWS besides, backed by a compliance table mapping each guideline to the technology it lives in and the exact test method.
It supports that with a real charting library for data visualization, mostly on Victory with some on ECharts, and a predictable quarterly release cadence. The official libraries are React and HTML/CSS, with community ports reaching web components, Java and Rust.
Where it fits
PatternFly fits enterprise, data-dense applications, dashboards, admin consoles, OpenShift-style products, built in React, especially where complex tables and charts matter. Charts are React-only, and the non-React ports are community-led, so weigh that if you're off React.
Ideas to borrow
- 01.
Accessibility practice
Run every component through a screen reader by hand, not just an automated pass, and publish a table mapping each guideline to the technology and test method behind it.
- 02.
Process/automation
Gate component acceptance on an automated axe audit, so nothing enters the system until it passes.
