Editor Like Mujumaps


I can see the site Mujumaps has been using OSM, Can someone help me find out how they use the code of OSM and how i can get it to, im not trying to make a copy of there site, I just want to know how it’s done.

A point on the right direction would also be good.
Thank you


Maybe they make use of one solution listed at https://wiki.openstreetmap.org/wiki/Rendering ?

They do, you can see these are rendered PNG tiles by right clicking. All the styles seem to be separate. So standard PostGIS + Mapnik + renderd setup, probably.
