Alternative to Lulu
TinyShield is a great alternative to LuLu, with modern macOS firewall controls, transparent one-time pricing, and a new Lifetime Deal for lifetime updates.
This blog compares TinyShield with LuLu in terms of design, features, and licensing, including the new TinyShield Lifetime Deal for users who want lifetime updates.

What LuLu Gives You
If you're looking for a free and open source firewall for macOS, LuLu is a great choice. It's free, open source, and has a large community of users.
It's one of the best selling point feature of LuLu, it monitors all outgoing connections and prompts for user approval on unknown traffic. You can block traffic from a given app or IPs.
However, LuLu has some limitations:
Let's look at the main windows of LuLu. Liqid Glass UI is soon introduced on macOS 26. I belive Lulu doens't update it because it's not using SwiftUI.

Let's look at LuLu's Github Issues, the majority of them is releated to "LuLU doens't work or can't monitor network traffic". It hasn't been solved in the latest version, but the issue is still there.

It's a biggest drawback of LuLu, you can't see the domain name of the traffic. Technically, LuLu has supported DNS Lookup, but it doesn't work well. It shows the level 1 domain name, not the full domain name.
