What is the best OpenSource Soft for HotSpot?

Question

open source

It is planned to organize a HotSpot network around the city as soon as possible, the task was to find and raise an opensource server, and not to make a server for HotSpot on our own. There is no time to raise and configure, then write the admin panel. After a few days on the Internet, the maximum I found was old and unmaintained software.
I also found a very good PacketFence, but its functionality is very resource-intensive, and there are too many superfluous things. Access to Hotspot must be organized through social networks. networks, such as following on facebook or instagram.
I wanted to ask if someone saw something in the spirit of PacketFence, only simpler, I would be very grateful if you could tell me a good solution for this task.
Equipment with Wi-Fi, will be from different manufacturers
