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!

Once UI 1.5▲302When 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…

Uxia▲548Hi HN, As PMs (Google, Gopuff, Shiji), my cofounder and I ran hundreds of user tests over the years. And every time it felt broken: It could take 2–5 days just to get enough usable results We spent hours watching recordings to extract a handful of insights “Professional testers” rushed through tasks for pay, creating biased feedback Platforms often started at €10k+ per year, with hidden fees on top The result: slow iteration cycles, unreliable feedback, and user testing that often felt like a tax rather than a tool. We started asking: what if AI could help? Could synthetic users replicate…

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!

Many UI issues I’ve seen aren’t visual problems but unchecked assumptions about users. I built a small tool that takes a UI screenshot and makes those assumptions explicit, along with the risk of being wrong. It’s meant as a quick design pre-mortem or critique before shipping. Would love feedback on whether this way of critiquing UI is actually useful.

Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…
