Ruixen UI

What it does

I built Ruixen UI after struggling to find clean, reusable components for my own projects. What started as a personal toolkit grew into 300+ free React and Next.js components to help developers build beautiful apps faster.

240+ React sections and components for shadcn — hero blocks, pricing, footers, navbars. Tailwind v3/v4. Radix or Base UI. Free + Pro.

Marketing UI for shadcn projects. 240+ React sections and components for landing pages — hero blocks, pricing, footers, navbars, and the primitives around them. Multi-stack: Tailwind v3 or v4, Radix or Base UI. Free catalog plus Pro templates. Design glassmorphism, gradients and shadows in the browser and copy production-ready CSS or Tailwind — no account, no install. Frosted-glass UI — tune blur, transparency, borders and gradients, then copy CSS or Tailwind. Linear, radial and conic gradients with stop-level control and one-click CSS & Tailwind export. Layered box-shadows, elevation and neumorphism — copy as CSS or Tailwind in a click. Free 4K gradient backgrounds for heroes and cards —…from ruixen.com

In the maker’s words, at launch

Hey HN. The "last 30%" is animation polish. Easing curves, hover states, scroll triggers, reduced-motion, responsive behavior. AI gets you a working component in seconds. Making it feel finished takes 30-60 minutes. Per component. Every time.We got sick of it, so we built 300+ React components where that work is…

  I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

  Once UI 1.5Dec 2025 · once-ui.com · ▲299

  When I started my career and built my first design system, I was beyond excited. It took a lot of iterations, learning and 6 months of work to launch it internally. In the next job, I did it again, then at the following job, again… And no matter which company I worked for, 80% of the design system was the same. I’ve decided to work full-time on the design system I’ve always wanted, and today I’m launching and open-sourcing it. You can use it to build Next.js apps faster, and I’ve designed it in a way that it’s hard to go wrong with it: you can choose any settings, and you’ll end up with a…

  Hey HN, A few years ago, when I was working as a freelance web developer, there were many projects that used repetitive layouts and designs That's when I built my own collection of basic UI components like buttons and all. At that time, I was using CSS, so I styled my components using CSS. Later, I decided to open-source these components, and that’s when I created HextaUI After a few months, I found out about Tailwind CSS, so I decided to recreate all components with better design, modularity, and accessibility. This time, I also added animated components, not just base components. After…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Strange Attractors▲804

  I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  Autism Simulator▲779

  Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
