HAProxyHAProxy excels in balancing Layer 7 and 4 traffic, essential for handling high-volume applications and APIs. Its features include SSL offloading, VRRP redundancy, path routing, and Kubernetes ingress control. Users value its reliability, efficiency, security, and load balancing. There are calls for improvements in logging, monitoring, cloud integration, and enhanced configuration management.
HAProxy is free software. There are optional paid products (support/appliances).
I think that the pricing is very fair, I would definitely recommend buying the Enterprise license.
