"Successful POC with HAProxy Ingress Controller and Fusion. Fantastic team and support."

4.5/5

What do you like best about HAProxy?

We were looking into alternatives to using the Nginx Ingress Controller for one of our products. Their team was super responsive and helpful throughout the entire process. Their technical team was able to resolve all the concerns and questions we had. We ended up not going with the product as we are a lean startup trying to preserve our runway, but we have it in our backpocket if we ever switch. Highly recommend HAProxy to anyone needing their type of service. Their Fusion product has a lot of cool features that can be appealing if needed. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

No negatives we discovered in our POC. Maybe that we would have to run our own infrastructure. Some startups like to lean towards a fully managed service and be more hands-off. Review collected by and hosted on G2.com.
