How about bisq.network? It is open source DEX? I think it is one of the most popular DEX as far as I know. And there's a lot of DEX that members here have been playing around for years, like Etherdelta, although I agree that Binance DEX is not really that decentralized though.

I'm not really sure about (https://blockdx.com/) though, maybe it's good alternative, maybe not. If it's good then there's no need to shill for it. Sooner or later the community will find about it, give their comments around.
