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!
