Hey, Oye here 👋 This is Coinstate, a real-time cryptocurrency price tracker that brings all exchanges into one clean dashboard. I built it because comparing crypto prices shouldn't mean opening 10+ browser tabs or constantly refreshing pages. With Coinstate, you get live prices from all major exchanges in one place, powered by Bun's native WebSocket for sub-second updates. When trading crypto myself, I was frustrated with the lack of a simple, fast aggregator that showed everything at once. Most tools are either too slow (30-60 second delays), too complex (overloaded with charts), or closed-source (can't verify the data). So I built Coinstate for traders, investors, and anyone who wants to track crypto prices without the hassle. Built with Bun runtime, achieving performance that's 5x faster than traditional Node.js solutions: ⚡ Real-time WebSocket updates (sub-second latency) 🔌 10+ exchanges supported (Binance, Coinbase, KuCoin, Kraken, Gate.io, HTX, Bitget, and more) 📊 Side-by-side price comparison 🚀 100,000+ concurrent connections 💾 60% less memory per connection 🔥 Native WebSocket (zero dependencies) 📈 Smart throttling & deduplication 🎯 Clean, responsive interface ⚙️ Redis caching (<1ms hits) 🌐 No account needed 🆓 Completely free 📖 Open source (Apache 2.0) 💻 Modern monorepo architecture 🧪 Production-ready code 📚 Full documentation included 🔓 Transparent & verifiable ⚡ 500,000 messages/sec throughput 🎨 Built with React 19 & TailwindCSS 4 If you've ever felt the pain of tab hell when checking crypto prices, you'll love Coinstate. It's open source, so you can see exactly how it works and even self-host it if you want. Check it out at coinstate.co 🚀 GitHub: github.com/oyeolamilekan/coinstate
