BalanceNG and Balance are both from the same company. Besides of that there’s no further relationship between Balance and BalanceNG. BalanceNG is a complete Layer2/Ethernet based load balancer for Linux, whereas Balance is a TCP only proxy tool with load balancing capabilities. BalanceNG and Balance do not share code since the design approaches differ substantially. Anyway, the Balance project will be continued as before (see https://www.inlab.net/balance/).
