"Outstanding Performance and Excellent Support in an Open-Source Load Balancer"

4/5

What do you like best about HAProxy?

This open-source load balancer offers outstanding performance and comes with excellent support. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

One small suggestion I have is that it would be helpful if the configuration were available in a standardized format. This would make it much easier to create templates or automate the generation process. Review collected by and hosted on G2.com.

Response from Nick Ramirez of HAProxy

Thank you for the suggestion about a standardized format. That's actually something available in HAProxy Fusion. There's a YAML version of the configuration.

"Exceptionally Reliable and Stable Software"

5/5

What do you like best about HAProxy?

It just works. Stable, reliable. We use HAProxy in front of a Redis deployment on K8s to make it highly available. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Our pain point today is in regards of observability. How to efficiently connect all the relevant metrics with our Datadog provider. Review collected by and hosted on G2.com.

"HAProxy works so well you forget it's there."

5/5

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. Review collected by and hosted on G2.com.

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.

"Widely Accepted, High-Quality Open Software"

5/5

What do you like best about HAProxy?

We always prefer to use widely accepted free software. It is also high quality and offers a multitude of options free of charge for most uses, although as a large university, we prefer the extra features offered by the paid version.

Today, it is undoubtedly our software of choice. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Sometimes it is hard to debug or follow the flow of usage. Review collected by and hosted on G2.com.

Thanks for giving us feedback. We're working to improve our dashboards and debugging tools.

"Easy to use for my case!"

5/5

What do you like best about HAProxy?

The ease of use and the different amount of things I can do with it Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Back then for defining an ingress controller i needed 3 of them so I had to define separate yaml files and that felt a little copy pasta, dunno if its still like that Review collected by and hosted on G2.com.

Response from Nick Ramirez of HAProxy

edit

Kubernetes does use many YAML files. But there are many ways to implement load balancing. We've just released a Gateway API product.

5/5

What do you like best about HAProxy?

Key strengths of HAProxy:

1. Very high performance under heavy load.

2. Excellent reliability and stability in production.

3. Fine-grained control through configuration (ACLs, routing rules).

4. Rich health-checking and failover capabilities.

5. Robust security features (rate limiting, DDoS mitigation, TLS termination).

6. Strong real-time observability and metrics.

7. Active community and long-term proven track record. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Main dislikes, briefly:

1. Config can be complex.

2. Weaker dynamic discovery vs Envoy.

3. Debugging configs can be slow. Review collected by and hosted on G2.com.

Response from Nick Ramirez of HAProxy

edit

Thank you for writing this review. For discovery, much of it's built into HAProxy Fusion as an enterprise offering. Complex configurations are something we hear the most often. We're hoping that writing more tutorials will help.
