The Windows equivalent would be Monitorian (https://github.com/emoacht/Monitorian). It doesn't have the adaptive curve algorithm, but I've been using it for over a year and it's indispensable.
As an alternative to low-end VPS's it's not the worst idea in the world at $5 a month. It'd cost more than that to upgrade your home's cable internet connection to be able to serve traffic decently.
