Open-source designs for interactive + animated interactions
Once UI 1.5 is about bringing wonder back to UI engineering. We’re introducing new visual effects — weather, particles, matrix-style dots — all drop-in and usable in just a few lines of code. You also get a new generation of chart types built for live data and real-time dashboards. Only in Once UI. A toolkit for indie builders who want their product to feel alive, expressive, and unmistakably theirs.
Thanks for stopping by.
Once UI 1.5 grew out of the same curiosity that drives https://designengineers.club — experiments in motion, mood, and how interfaces feel, not just how they look.
This update is our step toward more expressive, living interfaces: weather systems, particle fields, new forms of charts for real-time data.
Ask me anything — happy to share the thinking behind it.
