This is the codebase https://github.com/haveno-dex/haveno and its working just for testnet because they want to be software provider and not a runner of the exchange. Makes sense Imho, others will need to run it if they want and its up to the network runner to prove they are good actors and the community to use and vet them. I would use whatver has been around for longest as haveno.com/aloha need to lift their game.
