HAProxy Reviews & Product Details

What do you like best about HAProxy?

Update for 2025:

We purchased the enterprise version along with Fusion after a few years using the Aloha appliances and have been really impressed by the centralization and monitoring that Fusion provides. We have been leveraging HAPEE as a key component in our companies network now, allowing us to easily direct users to any specific datacenter we need. Support is still awesome. They are very open to receiving input from their customers.

Previous:

I enjoy having an interface without extra frills or anything fancy. It makes it simple to input your config, easy to check the status of your applications, and quick to deploy. When you have questions or need configuration assistance, the Aloha team does an excellent job in helping. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

3 years later, and still no complaints, it just works. Review collected by and hosted on G2.com.

What do you like best about HAProxy?

The performance and manageability. You can use conventional configuration files and you can manage with an API. Community edition easily serves internal needs and is easy to install and configure. When considering production we need a cost efficient product that came with support. HAProxy Enterprise Edition (HAPEE) fits that bill. Our expensive hardware Load Balancers could do the job but at astronomical prices. HAPEE comes with a lot of modules out of the box for some advanced use cases. Creating a highly available pair of LBs or integrating in SAML to your auth flow. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

I don't have much to dislike. For some the loss of a GUI will be upsetting but that's not a problem on my team. As of today there are no historical stats kept by the software. You can see realtime stats all day but it's on the user to pipe them into software to keep historical data. Review collected by and hosted on G2.com.

What do you like best about HAProxy?

- High Performance: HAProxy handles high volumes of concurrent connections with low latency, making it ideal for high-traffic environments.

• Observability: Built-in stats page and integration with Prometheus make monitoring easy and transparent.

• Open Source & Community-Driven: Great documentation and a vibrant community. It’s reassuring to know you’re building on a trusted, well-maintained project. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Nothing that I dislike however with a tool like HAProxy the learning curve can be steep for newcomers. The configuration syntax, while powerful, takes time to master.

That said there is an amazing team behind the software which is very active with both the Community & Enterprise users. Review collected by and hosted on G2.com.

What do you like best about HAProxy?

HAProxy is highly reliable, fast, and efficient, making it a top choice for load balancing and high availability. I like its robustness, flexible configuration, and support for advanced features like SSL termination, health checks, and traffic routing. It's lightweight yet powerful, ideal for both small and large-scale deployments.

The customer support team is pretty good at reposnidng to any issues Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

While HAProxy is powerful and efficient, there are a few areas that could be improved:

Configuration Complexity: The configuration syntax can be unintuitive for beginners. More user-friendly tooling or a modern UI could ease adoption.

Observability: While it provides stats and logging, deeper built-in observability (e.g., native Prometheus support or more detailed metrics) would help with troubleshooting and performance monitoring Review collected by and hosted on G2.com.

What do you like best about HAProxy?

We use HAProxy to load balance and stabilize on premise and cloud, environments, windows, and Kubernetes based applications. We’ve enjoyed the future set of the fusion control plane and all that it has to offer, gaining valuable insights into our application requests, front end, and back in statistics, and usage data. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

We don’t dislike anything, just hungry for education around haproxy and additional feature training so we can funnily use everything offered. Review collected by and hosted on G2.com.

What do you like best about HAProxy?

I like the HA Proxy Fusion Control Plane features and functionality we now have a single pane of glass to see all of the requests with great search functionality. Using this product to maintain consistent configurations across all of the HAProxy instances is extremely valuable and helps prevent mis-configuration using text editing on multiple HAProxy instances.

What do you dislike about HAProxy?

With the fusion product the CLI Editing is gone and I can use the browser and with the upcoming ACME Support I don't have any thing to complain about. It just works. They have great support and a good ticketing system that is easy to use. Review collected by and hosted on G2.com.

What do you like best about HAProxy?

We've been using HAProxy for around a decade, initially starting with the Community Edition and gradually expanding its footprint. We used industry-standard SLBs from major vendors, but the exorbitant price tags and outrageous support costs were becoming unsustainable. Two years ago, we leaped HAProxy Enterprise Edition (HAPEE) with the Fusion Control Plane (FCP), and it's been a game-changer.

Here's what we love:

Performance: HAPEE's performance is impressive. Even without leveraging hardware acceleration (which they support through Xeon Platinum chips), it easily handles our traffic load.

Stability: Since migrating, we've experienced rock-solid stability. HAPEE has proven to be a reliable workhorse.

Full configurability: HAPEE offers complete control and customization, allowing us to tailor it precisely to our needs.

Fusion Control Plane (FCP): The FCP has revolutionized our workflow, enabling full transactional changes across our clusters. This was a huge pain point with our previous solutions.

Unbeatable Support: This is arguably HAPEE's strongest point. The support team is phenomenal. They're available through Slack, providing near-instantaneous responses and practical solutions. We've dealt with companies charging 10x or 30x more for support that pales in comparison. HAProxy's support team sets a new standard.

Cost-Effectiveness: The pricing for HAPEE is significantly lower than any other comparable solution on the market. It's a breath of fresh air after years of being squeezed by our previous vendors.

Community Edition: We also utilize the HAProxy Community Edition for simpler micro-deployments, and it also excels in that role.

We've moved to HAProxy EE, and the cost/performance/support are so good we are not looking back. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Honestly, there's not much to dislike, but the Fusion Control Plane (FCP) has some growing pains. While it does many things exceptionally well, it's still under active development, and occasional kinks need to be ironed out, or some things you would expect haven't been implemented yet.

What do you like best about HAProxy?

My company has used HA since I started 6 years ago and all I can say when a tool is rock solid and it works it just works. We have 3 total proxys loadbalanced between our stage and production systems and it handles the load traffic perfectly. The support in the slack channel is a highlight especially if your trying to find a solution for a rule or a way to rewrite a rule to optimize it. Overall, I highly recommend HAProxy for anyone looking for a robust and efficient load balancing solution. It can also add WAF support if you don't want deal with a dedicated WAF provider.

What do you dislike about HAProxy?

The dislike are small but can bite you from time to time for newcomers that use apache or nginx the language curve could be alot to over come but HA does have a good wiki to find out rules. Besides that I don't have any issues. Review collected by and hosted on G2.com.

What do you like best about HAProxy?

HAProxy stands out for its exceptional performance in dynamic and high-load environments, making. The addition of the Fusion control plane further enhances its capabilities, providing powerful tools for managing and securing large-scale deployments. Whether you need efficient load balancing, comprehensive observability, or advanced security, HAProxy with Fusion offers a robust solution.

Customer service was wonderul to work with. I had two initial questions that were solved easily from support over email. This made implementation quick and easy. Converting our NGINX over to HAProxy was a trivial and the Fusion Control Plan intergrates well and makes changes and versioning easy. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

For smaller deployments a single node with Fusion deployment would be ideal. We work with a lot of SMB businesses that the price is limiting our options for HAProxy. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

One downside of HAProxy is its steep learning curve, especially for those who are new to load balancing or have less experience with networking concepts. Its configuration files can become quite complex and difficult to manage for larger setups, especially when you have many backend services or advanced routing rules.
