24 alternatives to Once UI 1.5
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…
Once UI 1.5 is an open-source design toolkit that provides pre-built interactive and animated UI components for developers. It includes visual effects like weather, particles, and matrix-style dots, plus new chart… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

21st.dev▲1,211I 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!

Hello everyone! I'm a solo developer who's been doing UI/UX work since 2007. Over the years, I watched design tools evolve from lightweight products into bloated feature-heavy platforms. I kept finding myself using a small amount of the features while the rest just mostly got in the way. So a few years ago I set out to build a design tool just like I wanted. So I built Vecti with what I actually need: pixel-perfect grid snapping, a performant canvas renderer, shared asset libraries, and export/presentation features. No collaborative whiteboarding. No plugin ecosystem. No enterprise…

I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

Hello. This year I dived into UI/UX area and at the same time I work as a web developer. I sincerely love making good UI. But at my full time job it's not always possible due to different reasons =\ So I've been posting random UI/UX staff on Twitter, then I made a free book that had 50 tips (posted it here as well). I decided to finish this year by collecting everything I learned and here it is: https://akcium.gumroad.com/l/ui-ux-tips. This time it's a paid one. But, you can check ~20 pages of it, just go to…

Hey HN, I’m Kiet – one half of the two-person team building Onlook (https://beta.onlook.com/), an open-source [https://github.com/onlook-dev/onlook/] visual editor that lets you edit and create React apps live on an infinite canvas. We launched Onlook [1][2] as a local-first Electron app almost a year ago. Since then, “prompt-to-build” tools have blown up, but none let you design and iterate visually. We fixed that by taking a visual-first, AI-powered approach where you can prompt, style, and directly manipulate elements in your app like in a design…

Hey Hackers! My name is Alex and I’ve been working on this project for the past 8 months with the support of Figma Creator Fund. I’d love to hear your thoughts from your experience working with designers & component libraries. I started out in design and later got into coding, so I understand both sides really well. I did UX Design for 12 years at startups, at my own studio and at Wix, and then worked as a front-end dev at Wix for 2 more years. I've noticed a common problem: most component libraries work great for devs but not so well for designers. In my experience working with big teams,…

Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards. I wanted to understand how they do it, so I started reverse-engineering their components out of curiosity. One thing led to another, and I ended up building a small library of reusable, animated components based on what I found. The library is built in React and Framer Motion. I’d love to hear your feedback

HextaUI▲25Hey 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…

Hey hn, this has been something I've been working on for the last few months and is finally robust enough to really show off. I've been pretty tired with the design outputs of LLMs for a while, and I've always thought diffusion offered much more creative / on brand design outputs, even before they were able to render text. I had enough conviction for this to leave my role over at Figma to build Diffui. The goal is to allow for you to design your full web app as quickly as possible, in a figma-like interface, and then hand that off to an agent to build. The page shows some interactive…

Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system. I wondered: "What if AI could understand our design system and generate React components that actually match it?" Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

Hi there, friends! I built a fun side-project called Fancy Components to explore and recreate some of the more unique, funky, unconventional, and sometimes useless UI designs & microinteractions you might see around the web. Built (mostly) with React, TypeScript, TailwindCSS, and Motion (formerly Framer Motion). Just copy the source code into your project, and you’re good to go. Each component includes examples, demos and also a documentation to help you understand how it works and built. It’s 100% free and open-source!
