A constraint-driven UI system for building scalable, production-grade interfaces. Stop fighting CSS. Start shipping engineered products.
Designed with rules.
Shipped with confidence.
Stop optimizing for the happy path. Your users will click the button 50 times, drag the modal off-screen, and paste emojis into the number field. Falnix is armored against the chaos of real-world usage.
Most layout engines break at 3 levels of depth. Falnix uses isolated coordinate systems to handle infinite nesting without z-index collisions.
Inputs reject malicious patterns before state updates. We don't trust user data.
Modals trap focus. Dropdowns return it. The keyboard is a first-class citizen.
Components enforce strict re-render limits. Expensive calculations are memoized at the root.
Every Falnix component is composed of discrete, typed primitives. We export the raw parts so you can recompose them. This library was written by people who maintain large codebases.
Strict discriminated unions. No optional chaining guesswork. If it compiles, it works.
Styles are statically extracted or mapped to atomic classes. No emotion-style overhead.
Structure without surrendering control.
Core tokens (spacing, timing, color primitives) are locked. This prevents "magic numbers" and ad-hoc deviations that rot a design system over time.
We don't wrap native elements unless strictly necessary. You still get full access to the underlying DOM node. It's HTML, just better.
Accessibility isn't a "nice to have". It's a system compilation error. Components without labels or keyboard nav will fail the build.
