CoinGecko's own widget is an ugly iframe that wrecks your Lighthouse score. We built a lightweight (5 KB), iframe-free, theme-able alternative — same data, drastically better embed.
The free Bitcoin price widget displays the live BTC/USD quote with 24-hour change arrow on any HTML page. CoinGecko's own free Bitcoin price widget is an iframe-based embed that ships its own CSS and breaks responsive grids. This one renders as inline HTML in your DOM, weighs 5 KB gzipped, and updates every 60 seconds via a single backend round-trip that we cache for everybody — so even a Hacker News spike doesn't dent CoinGecko's free rate limit. Drop the script tag, set ?coin=bitcoin if you want explicit, otherwise BTC is the default.
To embed crypto prices on website pages, paste the FeedPulse crypto ticker script tag and pass a comma-separated list of coin IDs (?coins=bitcoin,ethereum,solana,cardano). All four prices render in a scrolling marquee or stacked column, your choice. To embed crypto prices on website blogs (WordPress, Ghost, Substack), Shopify product pages, or plain-HTML landing pages, the same snippet works — no platform-specific plugin, no per-platform configuration. Supports the top 100 coins by market cap out of the box; obscure tokens work too as long as CoinGecko indexes them.
If you searched for 'crypto price ticker html' you've probably opened a dozen GitHub gists, half of them broken since the Binance API changed in 2024. The FeedPulse crypto price ticker HTML implementation is 3 lines: open script, src, close script. No fetch loop to maintain, no error handling for rate limits, no theme toggle to wire up — all of that lives server-side in the widget. The crypto price ticker HTML output is rendered into your DOM, so it's stylable, screen-reader-friendly, and crawlable. Free, no API key, no signup, supports all CoinGecko-indexed coins.
