Little Snitch and Little Snitch for Linux are a multi-platform pair of host-based application firewalls supported by Objective Development Software GmbH for macOS and Linux-based desktop computer systems, respectively. Each can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules.
Unlike a stateful firewall, which is designed primarily to protect a system from external attacks by restricting inbound traffic, Little Snitch is designed to protect privacy by limiting outbound traffic.[1] Until Little Snitch 4, it controlled network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple, but at version 5 it switched to using Apple's Network Extensions due to the deprecation[2] of kernel extensions on macOS Catalina.[3]
When an application or process attempts to establish a network connection, Little Snitch presents a dialog that allows the user to deny or permit the connection once, for a limited time, or permanently. The dialog also allows the user to restrict the parameters of the connection, for example allowing a given application to only connect to a certain domain or using a specific protocol or port. Little Snitch's integral network monitor shows ongoing traffic in real time with domain names and traffic direction.
The application (version 4) received a positive 4.5/5 review from Macworld.[4]
In 2026 a Linux version was released. While the macOS version is written in Objective-C, the Linux version is written in Rust.
