HAProxy vs ProxySQL: What are the differences?

What is HAProxy? The Reliable, High Performance TCP/HTTP Load Balancer. HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.

What is ProxySQL? A High-performance, GPL licensed MySQL proxy. It has an advanced multi-core architecture. It's built from the ground up to support hundreds of thousands of concurrent connections, multiplexed to potentially hundreds of backend servers.
