Sentry
- macOS
Monitors every outbound network connection from every app — see who's talking to the internet and where
Sentry passively monitors all network connections on your Mac and shows you exactly which apps are communicating, with whom, and where. It parses lsof output into a per-app breakdown with remote IPs, hostnames (reverse DNS), connection states, and country flags via a bundled MaxMind GeoLite2 database. Get 'first seen' alerts when an app connects to a server it has never reached before. Mark connections as Trusted or flag known tracker domains as Suspicious. Full connection history in SQLite with search, filtering, and CSV export. Sentry does not block anything — it's a transparency tool, not a firewall.
