"HAProxy from an UserPerspective"
4/5
What do you like best about HAProxy?

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.

What do you dislike about HAProxy?

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.

"Simple and Straightforward Experience"
4/5
What do you like best about HAProxy?

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 do you dislike about HAProxy?

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.

Response from Nick Ramirez of HAProxy

The whitespace thing is because of YAML. Thanks for letting us know.

"Absolutely fantastic"
5/5
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.

Please let us know what broke and was difficult to troubleshoot. HAProxy has a built-in configuration validator, but it could be another issue you're running into. We'd like to learn more.

"Reliable Load Balancing with Easy Configuration"
4/5
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.

HAProxy Fusion simplifies management of load balancer clusters. Have you checked it out yet?

"Great loadbalancer and WAF"
4.5/5
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.

"Reliable Performance with a Steep Learning Curve"
3.5/5
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.
