That's true - it may lack some advanced feature. But it's quite capable for the large majority of users. The only thing I don't like is that with newer macOS versions Lulu has dropped its own kernel extension in favour of macOS' built-in Network Extension framework that may have backdoor "bugs" built-in to allow Apple to spy on us (e.g. https://macresearch.org/mac-feature-bypass-firewalls-removed... ). I don't recall, but I think Little Snitch still uses it own custom kernel extension as macOS NEF doesn't still support all the features that LS offers.
Open source for good measure: https://github.com/objective-see/LuLu
i dont think lulu is an alternative, it is a rather small subset of features of what LS can do.
