LuLu
A free firewall that asks before apps go online
MacFree, open source
The verdict
Little Snitch costs $59 and LuLu costs nothing, and both warn you when an app on your Mac tries to reach the internet so you can allow or block it. LuLu is open source from Objective-See, turns each answer into a rule, and can import block lists or apply rules quietly without alerts. Expect a run of pop-ups in the first few days, and pick Little Snitch if you want to see every connection.
Get it if
You want to know which Mac apps phone home and block the ones you don't trust, at no cost.
Skip it if
You would find a few days of allow-or-block pop-ups more annoying than useful.
