"HAProxy is THE industry standard Load Balancer"

5/5

What do you like best about HAProxy?

I’ve been using HAProxy since version ~1.7, and it remains the only load balancer I can confidently recommend. The flexibility it offers is remarkable - from simple conditions to using Lua scripts, to shape the traffic exactly how you need.

It is easy to integrate and combined with automation software (like Ansible) you can deploy a fully reliable environment, essentially creating a turnkey solution ready for clients.

Project is well maintained with long support periods and upgrades can be performed in-place without disrupting traffic flow. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Some of the tooling around HAProxy - like halog is not well documented. Only HAProxy 3+ support JSON logs. Review collected by and hosted on G2.com.

The HAProxy Kubernetes Ingress Controller learns routes from Kubernetes. And HAProxy Fusion does this too. These may be what you're looking for!
