Cordon: a local ad blocker for macOS (first release)
I made a macOS menu bar app called Cordon. It blocks ads and trackers on your Mac using a local proxy and filter lists.
How it works:
Install a local certificate once
Turn on protection from the menu bar
Cordon filters traffic on your Mac
What you get:
Works across browsers and most apps
Live view of blocked requests
Filter lists for ads, privacy, malware and more
Custom rules if you want them
This is the first release (v0.0.1), so expect rough edges. Some apps ignore the system proxy or break with HTTPS filtering. You can add ignored hosts in Settings for sites that need to be skipped.
It only protects the Mac it runs on. It does not block ads on phones, TVs or other devices on your network.

Would love feedback, especially on certificate install, browser compatibility and anything that breaks with protection on.
