About this app

App Firewall shows you what your Mac is really doing on the network - and puts you back in control. Every app, background service and helper on your Mac quietly connects to the internet. App Firewall reveals every one of those connections in real time, shows where the data goes, and lets you block anything you don't trust with a single click. No account. No data collection. Everything runs on your Mac. WATCH YOUR NETWORK LIVE • See every connection as it happens - the app, the destination, the country and the traffic • Live per-app traffic right in the menu bar, updated every second • Search and filter connections by app, host or status BLOCK WHAT YOU DON'T TRUST • Take any app off the internet with a single switch • Block ads, trackers and telemetry with curated block lists • Write your own domain rules with wildcards (*.example.com) • Allowlist mode: block everything except the apps you approve UNDERSTAND YOUR TRAFFIC • Clear charts for the last hour, today, 7 days and 30 days • Your biggest data-using apps at a glance • Upload and download totals with connection counts SEE WHERE YOUR DATA GOES • A world map of every server your apps connect to, using an on-device location database • Country flags and cities on each connection • First-contact alerts when an app reaches a brand-new server STAY IN CONTROL • Pause protection for 15 minutes, 1 hour, 8 hours, until restart, or until you resume • Launch at login and live quietly in the menu bar • Export and import your rules; export connections to CSV PRIVACY BY DESIGN App Firewall never sends your browsing or connection data anywhere.
