Collaborative Editing Solution

I want to develop a private collaborative mapping website, in which I could import some shapefiles and let people edit it. Its important that it enables editing in the webpage, because I need to develop some gamification stuff like points, badges and leaderboards. I tried Umap but I don't think it allows me to develop the gamification part. Now I'm trying to setup a Openstreetmap Website (old The Rails Port) and delete all the data and import my vectors, currently I already did setup the RailsPort but now need the Tile Server. Is it the best way of doing it? I'm doing it on Ubuntu 18.04.
