What is Little Snitch?
Little Snitch combines a network monitor with application-level connection rules for macOS. Use it to investigate where an app sends traffic, inspect connection details and decide which destinations it may reach. The monitor groups activity by app, domain or country and displays traffic volumes alongside a map of server locations.
Connection alerts let you allow or deny new connections as they happen. If interruptions are unwelcome, Silent Mode initially allows new connections so you can review them later. Rules can target servers, domains, ports or protocols, while profiles and rule groups organize different network policies. Blocklists and encrypted DNS are also available.
The linked DMG is Little Snitch 6.5, not the separately advertised Little Snitch 7 beta. A download does not include an unrestricted license: without a license key, the demo runs for three hours at a time and can be restarted, while Network Monitor expires after 30 days. Older Macs running macOS 13 Ventura or earlier need a compatible legacy version rather than this download.
What it offers
- Inspect app connections, traffic volumes, server locations, ports and protocols in Network Monitor.
- Allow or deny connections through alerts or rules scoped to destinations and network protocols.
- Review new connections later with Silent Mode, which initially allows them.
- Organize policies with profiles and rule groups, and use blocklists to filter destinations.
- Encrypt DNS requests using supported DoH, DoT or DoQ services.
Good to know
- A paid license is required for unrestricted use. The unlicensed demo runs for three hours per session; Network Monitor expires after 30 days.
- The selected version targets macOS Sonoma, Sequoia, Tahoe and Golden Gate; macOS 13 Ventura or earlier requires a legacy download.
- Silent Mode initially allows new connections; it does not require an immediate approval for each one.
