HAProxy stands out for its raw performance and efficiency, handling huge amounts of TCP/HTTP traffic with minimal resource usage while remaining extremely stable under load.Its configuration language is powerful and expressive, making it easy to define advanced routing, ACLs, and load-balancing logic without bolting on extra components.] It also brings strong built‑in features like SSL/TLS termination, health checks, detailed logging, and observability APIs that fit naturally into production monitoring stacks.] Finally, being open source with an active community and solid enterprise options means it works well for everything from homelabs to large‑scale, business‑critical Review collected by and hosted on G2.com.

HAProxy can be quite complex to configure for advanced use cases, so the learning curve for newer users is steep and misconfigurations are easy. � It also lacks built‑in web‑server and rich caching features, so pairing it with other components is often necessary for static content and heavy caching needs.

We recently discovered with HAProxy a new level of security, limiting service exposure at near light speed only when strictly necessary, resulting in a more optimized architecture and savings of hundreds of dollars. Review collected by and hosted on G2.com.

At this stage, no changes are required to HAProxy. The service has proven to be stable, reliable, and well supported, meeting our expectations both technically and operationally. The current architecture and operating philosophy are sound, and the results clearly demonstrate their effectiveness. The best course of action is to continue working as you are now, maintaining the same approach and standards that have delivered such strong outcomes. Review collected by and hosted on G2.com.

If I want to find something to complain, maybe the SPOA for modsecurity and/or coraza is not straight forward, but I cannot blame haproxy for this Review collected by and hosted on G2.com.

Its performance and reliability. HAProxy is extremely fast, handles high traffic smoothly, and gives very fine-grained control over load balancing and traffic routing. Review collected by and hosted on G2.com.

HAProxy can be difficult to configure and maintain for complex setups.

The configuration is powerful, but it’s very syntax-heavy and not always intuitive, so debugging or scaling configs can get tricky, especially compared to newer tools with simpler abstractions. Review collected by and hosted on G2.com.

We use it for external load balancing of our kubernetes clusters, and it was very easy and straightforward to configure. The setup process felt clear and simple. Review collected by and hosted on G2.com.

More advanced very specific configuration can be harder to set up and manage if used inside Kubernetes. Less resources online than other k8s ingress/gateways out there. Review collected by and hosted on G2.com.

I find HAProxy's performance and reliability to be particularly valuable, as it serves as a robust load balancer and proxy. Its ability to handle cluster routing for both public and private URLs is exceptional, providing seamless connectivity and efficient traffic management. Additionally, I appreciate the statistics feature within HAProxy, which offers insightful data to monitor performance effectively. Furthermore, the initial setup of HAProxy is straightforward and easy, making it accessible and quick to implement within my existing systems. Overall, I have confidence in HAProxy as a highly dependable component of my network infrastructure, which is evident from my willingness to recommend it to others with a top rating of 10 out of 10. Everything about HAProxy works perfectly to my knowledge, enhancing both personal and team operations. Review collected by and hosted on G2.com.

I find the monitoring capabilities of HAProxy lacking, as I need help with visualizing the percentage of traffic distribution, and I wish there was a more intuitive way to manage traffic based on health checks. Additionally, the stats page could benefit from enhanced performance and features to make it more useful. Review collected by and hosted on G2.com.

HAProxy is the gold standard for load balancing. It’s incredibly fast, rock-solid stable, and able to handle massive traffic spikes without breaking a sweat. The configuration feels logical and straightforward, and the observability features offer deep insight into network traffic and behavior. If you need high availability and top-tier performance, this is the tool to use. Review collected by and hosted on G2.com.

Complex configuration: The haproxy.cfg syntax comes with a steep learning curve, and it can feel a bit “old-school” and rigid compared with more modern, YAML-based tools. Review collected by and hosted on G2.com.

HAProxy is built in C and designed for high throughput with very low latency. It can handle huge numbers of concurrent connections without needing a lot of resources Review collected by and hosted on G2.com.

The config syntax isn’t very intuitive at first. Concepts like ACLs, frontends/backends, and rule ordering can feel cryptic compared to something like NGINX or Traefik Review collected by and hosted on G2.com.
