I’ve been using AI to generate some repetitive frontend (guilty), and while most outputs felt vibe-coded, some results were surprisingly good. So I cleaned it up and made a ranking game out of it with friends, and you can check it out here: https://www.designarena.ai/vote

/vote: Your prompt will be answered by four random, anonymous models. You pick the one you prefer and crown the winner, tournament-style.

/leaderboard: See the current winning models, as dictated by voter preferences.

/play: Iterate quickly by seeing four models respond to the same input and pressing space to regenerate the results you don’t lock-in.

We were especially impressed with the quality of DeepSeek and Grok, and variance between categories (To judge by the results so far, OpenAI is very good for game dev, but seems to suck everywhere else).

We’ve learned a lot, and are curious to hear your comments and questions. Excited to make this better!

How about adding "mobile"? A lot of the time models tend to default to designs that don't make sense on mobile, even when instructed to design it as such.

Really? When I have a system prompt 'mobile-first design' it 100/100 works perfectly. What sort of things are you trying?

The designs are passable for a mobile version of a simple website, but really sub-standard compared to the average app on the Play/App Store, whether native (Swift/Kotlin) or hybrid (Flutter/RN). In B2B SaaS you can get away with the 5000th shadcn UI, not so much for B2C mobile. The days that stock Material UI actually saw usage there are a decade behind us.

If you have a tool/mode/prompt that creates good mobile UI designs, I'd love to know. Doesn't even have to generate code!
