This looks incredibly similar to wg-easy, which I see you have cloned in your github repo as well. Is this simply a SaaS-y frontend to wg-easy, or something different all together?
To answer your question though, wgeasy was definitely a source of inspiration as to the simplicity and cleanness of the design compared with other WireGuard related tools.
This isn’t a service I currently understand I need - I already have wgeasy and the site didn’t make it clear to me how this was better or different, so I don’t really have time to evaluate. I didn’t want to sign up for the beta if I wasn’t going to use it :)
I did have questions around your future monetisation approach and licensing, but also did not find ready answers.
WireHub is like wgeasy in regards to the UI (a nice list of devices and some buttons on the right), but different in that it doesn't run WireGuard, it just generates the configs.
So if you find yourself a bit worried of the single point of failure that is wgeasy (all the private keys are kept in plain text on the server running wgeasy), and you want more flexibility in your WireGuard routing (not just 0.0.0.0/24, per device rules), and the ability to securely share any of your configs with others, then maybe give WireHub a try.
No future plans as of yet. This is just a side project.
