Hello!
I can help you. Tell me, do you want to use the software that will be installed on your web server?
I offer a cloud solution that works with routers from different manufacturers.
You can choose authorization methods, customize the authorization page design and add a guest page.
In the control panel, you can monitor the list of authorization requests, examine customer information, monitor traffic, and so on.
The cost depends on the tariff plan: ~ $15-50/month.
We can also discuss the software for installation on your own server, this should be discussed individually.
Hope for quick feedback.
Thank!
