- Non-HTTP Health checks are easier that with nginx in that they often come pre-made as opposed to nginx which often forces you to write your own
matchdirective. - Fewer instances where you run into paywalled features. Many of the more advanced features in nginx are incredibly useful especially for enterprise users but you’ll often run into Plus-only features seemingly at random.
Features that Nginx has that HAproxy does not:
- Full HTTP web server implementation. haproxy can only route HTTP traffic. It lacks support for things such as FastCGI or WSGI for communicating with web applications.
- haproxy does not support caching responses. This means if your dynamic content changes rarely then these are always retrieved from the backend for each request over and over.
- As a consequence of the above, using nginx for both load balancers and application servers makes it easier to support your overall architecture by re-using knowledge and experience from one for the other.
- Load balancing for UDP protocols such as syslog or DNS.
- In my opinion, development of the core nginx product (both Plus and OSS) seems to be proceeding at a pace that exceeds haproxy’s development.

Other than open source Citrix Netscaler/ADC is a virtual appliance that is reasonably priced:
