AlignUI’s website is a brilliant exercise in “show, don’t tell” design—the entire experience functions as both marketing material and living documentation for their React component library. The soft warm-gray background is overlaid with subtle ruler markings that evoke a design tool interface, immediately signaling precision and alignment to their developer audience. The hero’s split-panel layout featuring a live code editor alongside rendered UI previews demonstrates the product’s value proposition without a single extra word. An orange accent color punctuates the neutral palette strategically, appearing in the logo, PRO badges, and interactive elements.

What elevates this design is its meticulous attention to the developer experience it represents. The interactive task buttons (“Add social login buttons,” “Add a divider,” “Make button blue”) animate through completion states while simultaneously updating both the code panel and live preview—a choreographed demonstration of the component library’s flexibility. The dark feature grid section provides striking contrast and breathing room between content-heavy interactive sections. Every visual choice reinforces the core product promise: components that are flexible, consistent, and beautifully aligned between design and development.
