Everything you need. Nothing you don't.
Xandra gives you the structure of a design system with the simplicity of utility classes.
Namespace Architecture
Track deviations with the NS system. Audit, validate, and promote custom patterns into your design contract.
Zero JavaScript
Pure CSS. No runtime overhead. No build step required. Just import and ship.
Implicit Child Styling
One class on the parent. Semantic HTML does the rest. Cards, stacks, and layouts that just work.
Density System
Switch between compact and spacious layouts with a single class. The entire subtree adapts automatically.
VS Code Extension
Real-time diagnostics, intelligent completions, and inline deviation tracking right in your editor.
Contract Compiler
Seven CLI commands to validate, audit, graph dependencies, and promote deviations to official components.
Testimonials
Trusted by engineers who ship.
“Xandra replaced our entire utility layer. The namespace system caught three inconsistencies in our design system on day one.”
“We went from 2,400 Tailwind classes to 85 Xandra classes. Our CSS bundle dropped by 73%. The density system alone was worth the switch.”
“Finally, a CSS framework that thinks about maintenance. The deviation tracking is something every team needs but nobody built until now.”
