The main selling point over just buying a raspberry pi and installing it locally on your home network is that it only works out of the box on your home network. Opening up your network to the internet is not recommended for the average developer, and generally not recommended at all.

Yes, you can set up your own VPS for less than $9/mo. But not much less.

There is a lot of concern over logging the DNS entries. I'll put a notice on the site, but you are not only able to clear your logs at any time but are also able to turn off logging altogether. I do not keep your logs.

This is not a DNS provider, this is simply a layer that attempts to stifle known ads and trackers. You can already assume your DNS logs are being used somewhere, this does not stop that.

This does not use a VPN to hide your IP.
