Correction: Quora User has told me that Little Snitch is a MacOS application. The argument does still apply - MacOS software can be closed source and as such you don’t always know what it’s doing. Ubuntu (and indeed the Linux kernel) has Apparmor built in and the tools to run a firewall.

Little Snitch is probably the best host-based application firewall solution for macOS app. I’ve been using it for quite a while but recently ditched it when I found a free alternative that equally works great.

If you’re using the free version of Little Snitch, you have to deal with the fact that it automatically quits after every three hours. To avoid this, you have to buy the full version. If you’ve been looking for a free Little Snitch alternative that works with macOS Mojave and previous macOS versions, Lulu is what you need.

Unlike Little Snitch, Lulu is an open source software with its source code already on GitHub. This means that it’s not just free, but also anyone can contribute to its development.

Same approach to application firewall

If you’ve been using Little Snitch before now, you shouldn’t have a problem using Lulu. Lulu uses the same approach to application firewall as Little Snitch; it alerts you of outgoing connections and asks you confirm every connection your apps are trying to make.

After installing it, you can choose to allow all default Apple apps and existing third-party apps to connect to the Internet without confirmation.

The choice you make here depends on how you wish to use the program. Personally, I only allow Apple-signed programs to connect automatically, all third-party apps require manual confirmation to create rules.

Clicking the Block or Allow button determines whether the application will access the Internet or not. Checking the temporarily box makes the rule temporary for that specific program ID. It resets when you quit the app or restart your computer and the dialogue box will pop up again.

Just like Little Snitch, it has a panel where you can remove existing rules and add new ones manually:

Ever since I upgraded to macOS Mojave, I’ve been using the new system-wide dark theme which Lulu neatly blends in with.

For a free app, Lulu is incredibly well-built. It’s been about a week now and I haven’t encountered a bug. If you don’t want to spend a dime on a firewall app, this free little alternative is really worth trying. You can download it from the official website or take a look at the source code on GitHub.

Little Snitch is a host-based application firewall for macOS. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH.

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.^[2] Little Snitch controls network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple.^[3]

If an application or process attempts to establish a network connection, Little Snitch prevents the connection. A dialog is presented to the user which allows one to deny or permit the connection on a one-time or permanent basis. The dialog allows one to restrict the parameters of the connection, restricting it to a specific port, protocol or domain. Little Snitch's integral network monitor allows one to see ongoing traffic in real time with domain names and traffic direction displayed.
