I got tired of using calculator.net (looks like 2003) and OmniCalculator (ads everywhere), so I built my own: https://slickcalc.com
30+ calculators covering finance, health, math, and more. Dark theme, real-time results, mobile-friendly.
Tech stack: Next.js 16, TypeScript, Tailwind v4. All computation is client-side — no backend, no tracking. SSR for SEO, ~350KB total page weight, CLS 0.
Blog posts embed working calculators via MDX, which was fun to build.
No revenue yet, just a side project. Curious what tools you'd find useful.
Hey HN! I wanted to see how far AI coding assistants have come, so I challenged myself to build a Tetris game using Cursor AI. The whole project took about 8 hours from start to finish.
Tech stack:
- Next.js + TypeScript
- Works great on both desktop and mobile
- Clean code structure (thanks to Cursor AI's suggestions!)
Would love to hear your thoughts on AI-assisted development. Feel free to try it out and let me know if you spot any bugs!
The code is open source, and you're welcome to check out how AI helped shape the development process. Pretty cool to see how far we've come with AI coding assistants!
