AuraFlow is a library of 49 ready-to-use design system themes, delivered as CSS custom properties. Each theme is a complete set of 23 design tokens — colors, typography, spacing, shadows and more — so you can drop one in and your entire UI adapts. It started as something I built for myself in 2024: I love making themes but never have time to design one from scratch mid-project, and not every developer is a designer. Free and open source, it installs in about 30 seconds via npm or CDN. Launched with 46 themes, now 49 and counting.
What surprised me
AuraFlow started selfishly — I love making themes but never have time mid-project, and I just wanted to change the colors and the vibe without rebuilding everything. The surprise came when I realized the hard part wasn't the CSS, it was the people who don't like CSS. Not everyone building apps is a designer; mixing colors that actually work together is a skill, and CSS can be intimidating. So the real challenge became making it effortless for someone who'd rather not think about any of it — one import, no runtime, sensible defaults, drop it in and move on. Making it that simple for others took far more discipline than making it work for me. (It also took me two years to stop tweaking and actually ship it — turns out that was the hardest part of all.)
