What Little Snitch is

Little Snitch is a paid macOS utility that shows where a Mac connects to the internet and lets users allow or deny connections. Alerts appear when an app wants network access. Network Monitor analyzes activity in real time, including data volumes, server locations, ports, and protocols, while an interactive chart can display current and past traffic for up to twelve months. Curated blocklists receive daily updates, and IP-based blocklists are supported. DNS requests can be encrypted with DoH, DoT, or DoQ. Rules can be arranged into groups and profiles, including groups subscribed from a remote server, and profiles can switch with network environments. Its command-line utility changes settings, exports rules, responds to alerts, and logs decisions. Processes may be identified by cryptographic code signature or file path. A 30-day trial provides full protection and functionality, but Network Monitor expires after 30 days; demo mode runs for three hours and can restart. The listed Single License costs €59 a month, billed annually, and covers versions 6 and 5.
