TL;DR: CryptoBubbles.org shows the top 1,000 cryptocurrencies as live, physics-driven bubbles. It runs on one Cloudflare Worker, fits inside a free CoinGecko API plan, renders pages in 64 languages, and has no ads, no sign-up, and no sponsored coins. Here is how it works and what I learned building it.
Why build another bubble chart?
Bubble charts are the fastest way to see the crypto market: one glance tells you whether the day is green or red and which coins are moving. The most popular tool of this kind is great, but over time, it added ads and “sponsored” tokens inside users’ lists, and the app reviews show people don’t like it.
I wanted the same idea with three rules I could promise forever:
- No ads and no sponsored coins.
- No sign-up….
