Vectison — Free Crypto Derivatives Data - Free live crypto derivatives data on one screen

Hi PH 👋 I'm an independent developer and systematic crypto trader. I built Vectison because the derivatives data I check every day — funding, open interest, long/short, order flow, liquidation zones — is scattered across exchanges or locked behind paywalls (looking at you, Coinglass). Vectison pulls it all onto one screen, live, across Binance, Bybit, OKX, Gate.io, MEXC and KuCoin — plus an estimated liquidation heatmap, a Bitcoin rainbow chart, quarterly return history, and market indices (Fear & Greed, BTC dominance, altcoin season). One thing on purpose: it's a data tool — no buy/sell signals, no price targets. Just the numbers. Would love your feedback on what to add next (options data + aggregated OI are on my list). Thanks for checking it out!
