"Great open-source software, better Enterprise services"

4.5/5

What do you like best about HAProxy?

The core software (Community Edition) is really solid: really fast, feature-rich, low-footprint reverse proxy software, even compared to alternative software. It is backed by exhaustive documentation.

Enterprise edition adds features related to scaling and automation, making it enterprise-ready. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

A lot of cools features are only available in Enterprise Edition (which is fair)

Community Edition docs could be updated to easier to scroll through, with examples Review collected by and hosted on G2.com.
