"fast and flexible"

4/5

What do you like best about HAProxy?

It's fast, and has a lot of power and flexibility. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

The configuration language is bespoke and has a relatively high learning curve.

Currently no good options if you need FIPS compatible TLS at scale with good performance on an LTS release (although that isn't entirely haproxy's fault). Review collected by and hosted on G2.com.

What problems is HAProxy solving and how is that benefiting you?

Load balancing, routing to the correct service (currently with hub and spoke model), for redirecting and rewriting requests before directing yo backend services, for ensuring security related headers are added to all responses, also used in some cases to protect sensitive endpoints.

HAProxy has served us well for over a decade. Review collected by and hosted on G2.com.

We're bringing new options for TLS library support, so please check back!

"HAProxy Enterprise Load Balancer"

5/5

What do you like best about HAProxy?

HAProxy is straight-forward to configure. The addition of load balancers to the cluster is very fast and easy. Fusion control plane provides a UI for those that prefer it, and can be used to modify the load balancer on the fly. HAPEE also allows for gitops configuration management as a way for us to keep track of changes and maintain a source of truth. The HAProxy team was friendly and helpful, and worked with us to get started on our Proof of Concept quickly. Eric at HAProxy was very knowledgeable and has been very responsive with our questions. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Currently, we're not able to get tcp logging to write back to the fusion control plane. We can still review the logs on the local load balancer nodes, and all the tcp connections work perfectly, but it would be nice to have the logs show in the fusion control plane.
