I built a free crypto bubble map for reading market momentum visually

Hi everyone,

I've been working on Cryptobubblemap — a free web tool that turns the crypto market into an interactive bubble chart. I wanted to share it with the DEV community and get honest feedback from builders and traders who actually stare at market screens all day.

The problem I kept running into

Most crypto dashboards are tables: rank, price, 24h %, scroll, repeat. That works for checking one coin, but it's painful when you want a quick visual read on what's moving across hundreds of assets.

I wanted something closer to a heat map you can explore — without installing a desktop app or signing up for another portfolio tracker.

What Cryptobubblemap does

Each coin is a bubble on one canvas:

• Size reflects a market metric you choose (e.g. market cap or volume)
• Color shows price performance over your selected timeframe (1h → 1 year)
• Filter by category or exchange
• Switch fiat display
• Open a detail page for any asset

It's 100% browser-based. No install. Free to use.

👉 Try it here: https://cryptobubblemap.com

Who it's for

• Traders who want a fast scan of momentum
• Researchers comparing sectors or exchanges
• Anyone tired of scrolling endless ranking tables

Market data comes from established providers including CoinGecko.

What I'm working on next

• Sharper defaults for first-time visitors
• More ways to compare sectors at a glance
• Better mobile layout for quick checks on the go

I'd love your feedback

If you try it, I'd genuinely appreciate notes on:

1. Is the first screen understandable in under 10 seconds?
2. What metric or timeframe do you reach for first?
3. Anything confusing or missing for your workflow?

Thanks for reading — and if you've built something in the fintech or crypto visualization space, I'd love to hear what worked for you too.
