Overview

Little Snitch is a network monitor and application firewall for macOS. It shows an alert whenever an app tries to connect to the internet, so you can allow or deny that connection, and records activity so you can review connections by app, domain, country, port or protocol. Rules can be grouped and switched by profile, and DNS requests are encrypted.

Best for: Mac users who want to see and control which apps connect to the internet
Pricing: No prices are shown on the captured page; it offers a 30-day free trial and a 'Buy' link, with a licence key turning the demo into the full version.
