What is Sinkzone?
Sinkzone is a local DNS resolver that helps you eliminate distractions and get deep work done. It blocks all domains by default — only the ones you explicitly allow can get through. This means notifications, social media, news, and other time-sinks are unreachable at the network level — not just in your browser.
It features a modern HTTP API, wildcard pattern support, and a beautiful terminal UI for real-time monitoring and control.
It's lightweight, cross-platform, and built for hackers, makers, and anyone serious about focus.
Motivation
Most tools make you list what you want to block. But the internet is infinite — that list never ends. It's much easier to list the few things you actually want to allow.
Sinkzone was born from that insight. I was tired of coding sessions interrupted by Slack pings and email alerts. I needed something stronger than a browser plugin — a system-level kill switch for distractions.
Now I can code for hours uninterrupted. Even my son uses Sinkzone during chess practice to stay focused.
Sinkzone exists because I needed it. Maybe you do too.
