[mproxy](https://github.com/kevinmcconnell/mproxy) is a custom minimal proxy designed specifically for Kamal. It has two big advantages over Traefik: 1. Imperative deployments - we tell it to switch from container A to container B, and it waits for container B to start then switches. No need to poll for health checks ourselves or mess around with forcing health checks to fail. 2. Support for multiple apps - as much as possible, configuration is supplied at runtime by the deploy command, allowing us to have multiple apps share an instance of mproxy without conflicting config.

Kamal: Deploy web apps anywhere
From bare metal to cloud VMs, deploy web apps anywhere with zero downtime. Kamal uses mproxy for zero-downtime deployments. Works seamlessly across multiple hosts, using SSHKit to execute commands. Originally built for Rails apps, Kamal will work with any type of web app that can be containerized with Docker.
