I’ve been testing VPN services and somehow every one with a client has written their own. Proton, Windscribe, IVPN, Mullvad, AirVPN, NordVPN, and the list goes on.
Don’t these services all do the same thing? Connect to a server to get a list of servers, then use WireGuard or OpenVPN to make a connection, and have some fancy stuff like split tunneling or a killswitch. It should just take configuration by adding profiles per service and it should be possible to use the same client.
What am I missing?
You could make the same case for a browser, an email client, a graphics or video editor, etc. The UI is an interface to basic core processes that are usually the same that all have, with some extras on the top for uniqueness and features that might be more appealing than other UIs.
It’s also a potential trojan horse, security liability, etc.
