Show HN: Lightweight exchange rate checker (no cookies, no ads)

https://myip.casa/generalutilities/exchangerate
1•myip_casa•1h ago
Hi HN,

I built a very lightweight exchange rate checker that loads instantly, works without cookies, and doesn’t track users in any way:

https://myip.casa/generalutilities/exchangerate

The idea came from a simple frustration: most "exchange rate" sites are filled with heavy scripts, ads, pop-ups, cookie walls, and tons of unnecessary UI elements for something that should be fast and minimal.

This tool pulls live rates, shows only what you need, and keeps the page extremely small so it works well even on slow connections or older devices.

Tech notes: - No cookies, no analytics, no ads - Pure client-side fetch - Fast loading, minimal JS/CSS - Mobile-friendly by default

Feedback welcome, especially on: - accessibility, - edge cases, - UI clarity, - additional currencies or features you'd expect in a minimal tool.

Thanks for reading!
