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.</p> <h2> The problem I kept running into </h2> <p>Most crypto dashboards are tables: rank, price, 24h %, scroll, repeat. That works for checking one coin, but it's painful when you want a <strong>quick visual read</strong> on what's moving across hundreds of assets.</p> <p>I wanted something closer to a heat map you can explore — without installing a desktop app or signing up for another portfolio tracker.</p> <h2> What Cryptobubblemap does </h2> <p>Each coin is a bubble on one canvas:</p> <ul> <li> <strong>Size</strong> reflects a market metric you choose (e.g. market cap or volume)</li> <li> <strong>Color</strong> shows price performance over your selected timeframe (1h → 1 year)</li> <li> <strong>Filter</strong> by category or exchange</li> <li> <strong>Switch</strong> fiat display</li> <li> <strong>Open</strong> a detail page for any asset</li> </ul> <p>It's 100% browser-based. No install. Free to use.</p> <p>👉 <strong>Try it here:</strong> <a href="https://cryptobubblemap.com" rel="noopener noreferrer">https://cryptobubblemap.com</a></p> <h2> Who it's for </h2> <ul> <li>Traders who want a fast scan of momentum</li> <li>Researchers comparing sectors or exchanges</li> <li>Anyone tired of scrolling endless ranking tables</li> </ul> <p>Market data comes from established providers including CoinGecko.</p> <h2> What I'm working on next </h2> <ul> <li>Sharper defaults for first-time visitors</li> <li>More ways to compare sectors at a glance</li> <li>Better mobile layout for quick checks on the go</li> </ul> <h2> I'd love your feedback </h2> <p>If you try it, I'd genuinely appreciate notes on:</p> <ol> <li>Is the first screen understandable in under 10 seconds?</li> <li>What metric or timeframe do you reach for first?</li> <li>Anything confusing or missing for your workflow?</li> </ol> <p>You can also reach me at <a href="mailto:hello@cryptobubblemap.com">hello@cryptobubblemap.com</a> or on X: <a href="https://x.com/Cryptobubblemap" rel="noopener noreferrer">@Cryptobubblemap</a>.</p> <p>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.</p> showdev webdev cryptocurrency sideprojects
