That was just my anecdotal point that a Pi can handle typical home internet speeds over Wireguard without overtaxing the CPU. IMHO, Wireguard's setup is pretty trivial as is, especially moving to it after years (decades at this point) of various OpenVPN setups that require much more tinkering. So no need for external tools. But I'm glad they exist for those who find them useful. Either way, keep up the good work with your knowledge sharing, I'm a big fan of what you do.
