Hi, one of the developers here. Did not expect this to land on HN.

For iOS, my understanding was that Apple already provides a built-in firewall?

Besides, the APIs to track connections/flows per application aren't necessarily available on iOS [0]?

I used to hack on AOSP for a living, so kind of right at home with Android, right now.

That API you're linking is only available on macOS (see the column on the right side of the page).

Yeah, that was the point I was trying to make. I am not aware of APIs on iOS that let VPN apps track and block per app connections flows.

Digging a bit deeper in the developer docs, it looks like it may be possible? https://developer.apple.com/documentation/networkextension/a...

Given that the core firewall is implemented in Go, we should be able to port it to iOS without much worry. But first, must arrange funds to purchase a Mac and an iPhone :)

Just a heads-up that at the end of that support doc, it says the API is only available for managed devices on iOS.
