PureSnitch

Open-source application firewall

Description

You want to see where your machine is actually sending data, but commercial firewalls are pricey and closed. PureSnitch recreates that experience openly: a live world map plots every outbound connection by country, paired with a rule manager so you decide which app connects where.

Features



World Map: Plots outbound connections onto their destination country live.

Rule Manager: Set allow or block per application.

DNS Blocking: Filters ad and tracking requests by domain.
