HAProxy Reviews & Product Details

HAProxy is one of those rare pieces of infrastructure software that you can deploy and essentially forget about — it just works, handles massive traffic with minimal resources, and never surprises you. The combination of a transparent, single-file configuration with powerful features like stick tables, granular health checks, and zero-downtime reloads makes it the gold standard for load balancing. Review collected by and hosted on G2.com.

If I'm being honest, the configuration syntax can feel archaic — it's powerful but has a steep learning curve, and the documentation reads more like a reference manual than a guide, which makes onboarding painful. The lack of a native API for dynamic backend management (without reloads or the Runtime API's limitations) also feels outdated compared to more modern alternatives like Envoy, especially in Kubernetes-native environments where service discovery is constantly in flux.

What I appreciate most about HAProxy is its reliability and performance. It offers excellent load balancing management and remarkable stability, even under heavy load. Additionally, its configuration flexibility allows for finely tuning the behavior according to specific needs. Review collected by and hosted on G2.com.

What I like a little less about HAProxy is that the configuration can become complex on advanced infrastructures. A good knowledge of the product is often required to avoid subtle errors, especially with ACLs or certain routing options. Moreover, the configuration file syntax, although powerful, is not always intuitive for new users. Review collected by and hosted on G2.com.

it's lightweight, fast and easy to setup, and the enterprise fusion plane software is really a complete solution, also the customer support is quick and helpful, this software is our base frontline to the applications in the office so all users use it daily and add the new backends or any new site is easy, much easier on the Enterprise Edition Review collected by and hosted on G2.com.

im currently in a version that doesn't have the proper configuration for some features, but this is fixable with the support team, so rather than that nothing bad Review collected by and hosted on G2.com.

I really appreciate using HAProxy for its outstanding performance and reliability, as it is extremely fast and can manage a high volume of traffic with very little latency. This ability to handle tons of high-volume traffic with minimal latency is crucial for my use cases, which involve continuous or spike-based network traffic. Additionally, I find its security features impressive, with capabilities like a firewall, SSO termination, and rate limiting, all of which enhance the protection of our systems. HAProxy's lightning-fast speed makes it incredibly effective for data transmission in near real-time, handling very high volumes of data transfer effortlessly, which perfectly suits the requirements of my projects.

I find HAProxy to be quite a complex solution, which presents a challenge in terms of the learning curve. Getting up to speed with it requires a lot of patience and time to understand its intricacies thoroughly. Additionally, troubleshooting can be cumbersome due to the multitude of configurations and settings available, necessitating a deep understanding of the internal workings of the software. Setting it up was also not straightforward, and we needed support to establish the complex configurations needed to meet our specific requirements. Review collected by and hosted on G2.com.

I appreciate HAProxy for its robust reverse proxy capabilities, which greatly enhance the protection of my applications, especially the ones that do not natively support TLS. The ability to encrypt data between the application and the end user is a critical feature that ensures my data's security. I find the community support incredibly helpful; whenever I have questions, there is always someone to assist me, highlighting the strong community backing HAProxy enjoys. The initial setup of HAProxy was super easy, making the transition from previous tools hassle-free. This simplicity in setup and operation has made it an excellent choice for my home lab projects. Additionally, my trust in HAProxy increased significantly, particularly after Nginx was sold, positioning HAProxy as a more reliable choice for my needs. Review collected by and hosted on G2.com.

Nothing comes to mind Review collected by and hosted on G2.com.

As a user of the open source product, I find H a proxy to be pretty easy to configure, and flexible enough to handle multiple use cases, obviously including web proxy, but also Secure TCP and other based solutions. Review collected by and hosted on G2.com.

I wish it had a text user interface, because sometimes configuring it by editing. The configuration file directly is clumsy, and in many instances, HA proxy is installed on a virtual device that does not have administrative interface that is accessible remotely. But in my case, SSH access is pretty common for administrative needs. And a text user interface would be ideal in that circumstance. Review collected by and hosted on G2.com.

I use HAProxy as a load balancer in my company and find it to be exceptionally seamless, particularly due to its ease of use and extensive documentation. The documentation is incredibly helpful for general usage and understanding HAProxy’s functionalities. I also appreciate how HAProxy manages to address significant problems like DDoS, WAF, and security concerns, which are critical to our operations. This makes it a reliable tool for maintaining the security and efficiency of our services. Review collected by and hosted on G2.com.

I find the Web Application Firewall (WAF) capabilities in HAProxy not as effective as I would like, indicating there's room for improvement in this area. Additionally, during specific upgrades, the documentation provided isn't as extensive as expected, making it challenging to navigate these updates effectively. Setting up the initial configuration was somewhat hard, which suggests that the setup process could be more user-friendly. Review collected by and hosted on G2.com.

I find HAProxy to be an excellent tool for networking and routing, especially with its capability to route to multiple endpoints using weighted routing. It's incredibly portable and allows for easy management in setting up proxy endpoints for our applications. What stands out is how effectively it simplifies networking within our cloud architecture, making it an invaluable component of our infrastructure. The initial setup was straightforward and hassle-free, which was a significant advantage. Overall, these features contribute to my high regard for HAProxy, and I would rate it highly in terms of recommendability. Review collected by and hosted on G2.com.

I find the current HAProxy setup challenging when it comes to managing multiple regions or cloud environments from a single instance. This limitation can complicate our operations and requires improvements to effectively cater to diverse geographical deployments. Review collected by and hosted on G2.com.

I love that HAProxy functions as a lightweight load balancer utilizing significantly fewer resources, which helps our network run efficiently. It is capable of handling all TCP and UDP traffic, addressing network distribution and ensuring low latency and faster distribution between servers. The setup process is impressively simple, requiring only a few commands to get up and running. Compared to our previous experience with a RackSpace legacy load balancer, HAProxy provides a more manageable and reliable solution, allowing for easy SSL and TLS configuration. This ease of management and configuration truly sets HAProxy apart from other load balancers, supporting us in maintaining our own server effectively. Review collected by and hosted on G2.com.
