Ever wondered how far Bitcoin’s bid/ask drifts between Binance, Kraken, Coinbase, Bitget, and KuCoin — after fees?
Crypto Arbitrage Monitor is an open-source dashboard that polls public top-of-book prices across those five venues, builds a buy/sell matrix, and streams fee-adjusted spreads live. It does not place trades. It shows indicative opportunities so you can see where spreads open up.
Why try it
Five exchanges, public APIs only — no private keys
~3s poll cycles with WebSocket/STOMP updates (no frontend polling)
