This searches for arbitrage opportunities by comparing prices across Hummingbot-connected exchanges, treating fungible tokens as equivalent (BTC/WBTC, USDT/USDC). It queries CEX connectors by default and can pull DEX prices from Jupiter, Uniswap, and PancakeSwap via Gateway if you pass the dex flag. You specify base and quote tokens, set a minimum spread threshold, and it outputs ranked opportunities with buy/sell venues and profit margins. Built by the Hummingbot team, so it integrates cleanly with their API and Gateway setup. The DEX support is the interesting piece here since most arbitrage tools focus on centralized exchanges. Just note that BTC markets have geographic restrictions on some exchanges.
