Not really related to the product itself, but your landing page design looks close to the official Microsoft style which I dont have the best memories of..
It might be intentional to show the "seamless integration" to Windows users but my penguin loving soul got scared!
If it makes you feel better, all core development for Netrinos is done on Linux. Then, the code is adapted to work on macOS and Windows. Almost all of the code is cross-platform, including the UI. Only the implementation details are platform specific.
e.g. Linux uses nftables. MacOS uses pfctl. Windows, we had to write our own packet filter to avoid touching the often misconfigured Windows Firewall.
