This is a secure dns and adblocker that has evolved into a great privacy app. Yesterday i noticed it has added support for Wireguard and TOR as well as proxy. The app comes with a customizable firewall. It means you can have secure dns combined with vpn/proxy and firewall in one app.
P.S: I’m not the developer.
Why would you be “dependent” on it in any way? There’s no vendor lock in…
Because if at some point one of its features you use are going from from free to paid, & then you have no money for this (as too poor for it, or the will/ethic to pay, etc) while there are no free forks/alternatives for the service : you have a problem. Not everybody is as good users as us using iptables or wireguard, finding different alternative may be hard to understand for others. For example, as I’m not a good developper : I personnally feel dependant to a lot of foss apps & choices they make. If the matter here is related to privacy, I think it’s important to know that you may pay at some point for it.
