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.
his toolkit empowers indie builders to elevate their product’s UI personality without sacrificing development efficiency.
Do you plan to expand compatibility with additional frontend frameworks (e.g., React Native) to enable these components in mobile apps? Also, will there be pre-built UI templates that combine these animated effects with common layout patterns (e.g., SaaS onboarding flows)?
congrats! looks nice. QQ - does it support webflow and other types of implementation?
@lorant_one Open source interactive designs are valuable for the community! Animated interactions can be tricky to get right.
How do these designs perform across different frameworks? Are they optimized for Framer, Webflow, or code first implementations?
Would love to see how these handle responsive behavior.
This looks super nice - as an absolute beginner when it comes to all this stuff, can one use Once UI to create beautiful elements for their Squarespace/Wordpress site?
I could see how our tool could pair nicely with what Once UI offers, and I’ll go take a closer look at their launch to explore how this might streamline our interface needs.
Seems like a great alternative to doing it manually! I'm excited to have these for our UI
Love the update! Which part of UI 1.5 was the hardest to build, the weather system or the particle fields?
Very useful; it would be interesting to see how it performs in real time! Congratulations on the launch!
Nice launch—Once UI for Figma nails a key productivity gap for design teams. From a clarity/hook perspective: when a product team lands on your page for the first time, what’s the one statement you want them to believe in the first 10–15 seconds? Is it: • ‘Design teams ship 2-3x faster with one UI system.’ or • ‘Your design + dev stay perfectly aligned from day one.’ Because in UI systems the difference between “we built many components” and “you get an aligned team” often kills product adoption. Curious how you’re phrasing that moment for Once UI.
Love what you’re doing with Once UI. How does Vibe Coding (MCP) integrate with Once UI? Can I use it to auto-generate UI components directly from design tokens?
Love how 1.5 continues the core Once UI philosophy - interfaces with mood, motion, and personality.
The weather + particle effects unlock so many expressive use-cases, especially paired with the new real-time data charts.
Proud to be contributing. Every update feels like we’re bending code into something living.
Once UI is the first toolkit that actually feels like art. ✨
