I had a satisfying interaction with HA Proxy. The best part was the solid setup, and it felt like a strong option for security. I also appreciated being able to talk with them in detail and get my questions addressed. Review collected by and hosted on G2.com.

Nope nothing about this HA Proxy. Learning new things with them Review collected by and hosted on G2.com.

Its performance is nothing short of legendary; it handles staggering amounts of traffic with such negligible resource usage it feels like magic. But its true genius lies in its configuration. It’s a work of art—a pure, text-based DSL that gives you god-like control over every single packet. We wield its ACLs and stick tables like a surgeon’s scalpel to dissect and annihilate threats in real-time. It’s not just a tool; it’s a masterpiece of engineering that provides absolute, rock-solid stability. Review collected by and hosted on G2.com.

Honestly, framing anything about HAProxy as "negative" is to fundamentally misunderstand its purpose. People mention the "steep learning curve" or its reliance on the command line as if those are flaws. That's not a flaw; that's a feature. It's a deliberate design choice that filters out the dabblers. HAProxy doesn't hold your hand with a flashy GUI because it's a professional-grade weapon, not a toy.

What I value most in HAProxy is its predictability and low operational overhead. It performs its core task of traffic management with high efficiency and minimal resource consumption, which is a key requirement for our infrastructure. Its text-based configuration, while austere, allows for precise, repeatable deployments and integrates cleanly into our automation and version control workflows. It’s a stable component that does exactly what it's expected to do without introducing unnecessary complexity. In essence, it functions as a reliable utility that doesn't require constant attention.

Its strength in text-based configuration is also its primary rigidity. Debugging complex rules or troubleshooting routing issues can become inefficient and opaque, lacking the visualization tools or dynamic management offered by more modern solutions. Furthermore, any functionality beyond core load balancing, such as advanced WAF integration, often requires add-on solutions or enterprise versions, which complicates the architecture.

What I like best about HAProxy is its exceptional reliability and outstanding performance. It has been the cornerstone of our infrastructure, effortlessly handling immense traffic loads with remarkably low latency. The configuration is both straightforward and incredibly flexible, allowing us to implement complex traffic routing and load balancing rules with ease. This simplicity, combined with its powerful feature set, saves us a significant amount of time. We have complete confidence in HAProxy's stability; it consistently ensures high availability for our critical applications. The ability to scale our services without compromising speed or reliability is invaluable. It’s a robust, efficient, and well-documented solution that has proven to be indispensable for our operations. Ultimately, it provides peace of mind, which is the highest praise I can give.

While its power is undeniable, the learning curve for its more advanced features can be somewhat steep for newcomers. Furthermore, its primary reliance on command-line configuration, while efficient, might present an initial hurdle for teams more accustomed to graphical user interfaces for management.

The best about HAProxy is the precise ACL-based routing and how predictable it behaves under load—debugging is straightforward and rarely feels like guesswork. Review collected by and hosted on G2.com.

Nothing like that which is feel like a con. Review collected by and hosted on G2.com.

Quality separation of definitions. One configuration error won't take a server down Review collected by and hosted on G2.com.

No pre flight check? Rather know about server stability before the crash Review collected by and hosted on G2.com.

HAProxy configuration is very simple and straightforward, and it’s easy to get set up without much hassle. Performance has also been great in my experience. Review collected by and hosted on G2.com.

It’s not always the most up to date when it comes to emerging technologies. Review collected by and hosted on G2.com.

HAProxy integrates seamlessly into OpenShift as the default ingress controller. The performance under high load is excellent, and the configuration via annotations is straightforward for routing and TLS termination. Review collected by and hosted on G2.com.

Advanced custom configurations in OpenShift require workarounds via ConfigMap patches, which can be tricky. Better native support for fine-grained timeout and header manipulation without leaving the OpenShift abstraction layer would be helpful. Review collected by and hosted on G2.com.

What I like most about HAProxy’s simplicity is how it keeps powerful load balancing and routing features easy to understand and configure, without unnecessary complexity. Review collected by and hosted on G2.com.

What I dislike most about HAProxy’s whitespace sensitivity is that small formatting mistakes can easily break the config or cause subtle issues, making it less forgiving than it looks. Review collected by and hosted on G2.com.

What I like most about HAproxy is the flexibility its configuration offers and the degree of customization and sophistication that can be achieved using ACLs. We have faced different use cases that required very specific and out-of-the-ordinary configurations, and we have always been able to achieve the goal using some of the countless functions it provides. The manual is very comprehensive, and by reading it for a while, you can find the solution to all your needs. As for its robustness, the load it can handle without any issues is incredible. In case of need, the support is very good, fast, and effective. We use it daily and are delighted with it. Review collected by and hosted on G2.com.

To make a complaint, I would like there to be more updated versions in the official repositories of the most used distributions. Review collected by and hosted on G2.com.
