Most blockers try to filter out the bad stuff. I took the opposite approach: block everything by default, and only allow what I need. No distractions, no noise – just silence until I say otherwise.

It’s a local DNS forwarder, written in Go. Works on macOS, Linux, and Windows. No cloud. No dependencies. Just a binary.

• Monitor mode: logs DNS activity so you can see what to allow
• Focus mode: only your allowlist resolves – everything else gets NXDOMAIN

It’s kind of like Pi-hole, but reversed.
