Hands Off: Install (Free, one-time purchase of $49.99) Expensive (Costs even more that Little Snitch).

The app is pretty simple and easy to use. To sum up, Hands Off is definitely a strong contender if you are looking to replace Little Snitch. You can easily breeze through the advanced settings and create your own set of rules and app exclusion list. What I like about Hands Off is that it does not feel too advanced, unlike Little Snitch which can be overwhelming on the face for normal users. Whenever an app tries to establish a connection, you get a notification alert whether to allow or block the connection altogether. The app allows you to protect your privacy by enabling the sniffing mode which blocks all the applications and services from accessing any remote server. Hands Off easily ranks among the best Little Snitch alternatives because it has both advanced features and user-friendly interface. Simply put, if you are looking for a free Little Snitch alternative, there is no app better than Lulu. Only when you grant permission, apps will be able to establish a connection. Which essentially means that the moment you install Lulu, it will start blocking apps from accessing the internet. Also, the distinct part about Lulu is that it comes in pre-blocking mode by default. You can easily find apps which are making outgoing connections and block them straight away with a single click. Surprisingly, unlike other open-source apps, Lulu looks absolutely great with a beautiful user-friendly design and customizable interface. It’s an open-source app and completely free without any limitations on outbound or inbound connections.

Lulu is not only a Little Snitch alternative but one of the best firewall apps for macOS. Radio Silence: Install (Free trial for 30 days, one-time purchase of $9) 2. To sum up, Radio Silence is among the best Little Snitch alternatives and we recommend it without any reservation. Thereafter, you can block, inspect or allow the connection without jumping through hoops. And the best part is, just like Little Snitch, you will receive a notification prompt whenever an app or service tries to make a connection. Apart from that, you can go deep and monitor what processes are trying to establish a connection with online servers.
