Looks really streamlined!

Currently, when I need to focus, I use a separate device configured to block everything except 2-3 domains I really need to minimize distractions. What really makes Sinkzone interesting is the scheduling with focus mode which can be incredible useful. My current firewall, OpenSnitch only lets you toggle all rules at once, so Sinkzone could be useful for allowing just the focus domains.

I think a useful feature to consider is having different profiles which would essentially be collections of domains to allow. So you could have "focus", but also "work" or "kids" as well allowing for more flexibility.

As I previously mentioned, I'm currently using OpenSnitch [1] as a system-level firewall that has a similar allowlist-only functionality. While the popups to allow/reject a connection initially disturb your workflow, after a short period of usage, you end up with a small collection of rules and you'll pretty much only see them again when browsing new websites. The advantage over DNS-level blocking is that you also get to block per process and not just device (or network). Since it uses eBPF, processes can't get around it by using a different DNS server or something. I'm really missing profiles and scheduling though, so I hope you can build a viable alternative to switch to!
