"Unmatched Power and Precision for Professionals"
What do you like best about HAProxy?

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.

What do you dislike about HAProxy?

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.

"Reliable and Efficient, but Lacks Modern Flexibility"
What do you like best about HAProxy?

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. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

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. Review collected by and hosted on G2.com.

Response from Nick Ramirez of HAProxy

Thanks for reviewing HAProxy. As you said, many of the challenges are eased by the enterprise version, while the free, community version offers a robust load balancing solution.

"HAProxy: Reliable, High-Performance Load Balancing with a Steep Learning Curve"
What do you like best about HAProxy?

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. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

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.

"Absolutely fantastic"
What do you like best about HAProxy?

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.

What do you dislike about HAProxy?

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.

Response from Nick Ramirez of HAProxy

Thank you for this feedback about HAProxy! We may not have the power to force distributions to have more updated packages, but we're working on a way to provide those packages directly.

"Reliable Load Balancing with Easy Configuration"
What do you like best about HAProxy?

I use HAProxy for load balancing and reverse proxy, and it helps distribute traffic efficiently across multiple servers. I appreciate its reliable performance and high availability. I like the speed and easy configuration, which lets me handle high traffic with low latency, scaling and managing it effortlessly. The basic setup is straightforward. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

In complex use cases it's not easy to configure HAProxy. The basic setup was straightforward, but moving to TLS made it more complex to manage. Review collected by and hosted on G2.com.

"Great loadbalancer and WAF"
What do you like best about HAProxy?

It's a REALLY fast load balancer with almost limitless functionality. It's very easy to use with Fusion, which is getting more features every now and then, whilst maintaining stability. We also do really like the request explorer integrated in to Fusion. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

It has not always been as easy for us to implement it in our environment, but we solved this with great help of the HAProxy team and some custom scripts provided by them. Don't forget to document this, so you remember how everything is implemented and working together. Review collected by and hosted on G2.com.

It's good to here that you got the help you needed. Thank you for leaving a review!

"Reliable Performance with a Steep Learning Curve"
What do you like best about HAProxy?

What I like best about HAProxy is its reliability and performance. It efficiently balances traffic across multiple servers, ensuring high availability and minimal downtime. Its flexibility with advanced configuration options, robust security features, and strong community support make it an excellent choice for both small and large-scale deployments. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

One aspect I dislike about HAProxy is the complexity of its configuration for advanced setups. While it is extremely powerful, managing multiple frontends, backends, and ACL rules can become cumbersome, especially for larger environments. Additionally, debugging misconfigurations requires careful attention to logs and can be time-consuming. Review collected by and hosted on G2.com.

Which tasks are at the top of your list for making simpler? For instance, rate limiting? We're collecting feedback about how to simplify the configuration.

"Reliable and phenomenal support"
What do you like best about HAProxy?

We have used HAProxy Enterprise Edition for the past 2 years. Over this time it has provided reliable load balancing and has run in the background without the need for intervention. The upgrade procedures have yet to give us any headache. The ACL system is robust for complex routing and Fusion Control Plane makes managing multiple clusters convenient. The support team is very knowledgeable and quick to respond. They have a slack channel that makes getting help pain-free and keeps things moving along. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

The config syntax takes some getting used to. It's powerful once you learn it, but it's not very intuitive at first. Review collected by and hosted on G2.com.
