The other options I considered were Mapbox and MapTiler, since it seems that actually self-hosting everything yourself is a bit demanding on hardware resources. I mean, I love that you can get the OSM dataset into PostGIS pretty easily, but getting the vector data or raster tiles to the client can take a bit of CPU power and bunches of storage! I wonder whether I missed any other good cloud services, or a self-hosted stack that would make things easier.
That said, I wonder why so many seem to be moving away from raster tiles to vector data. I guess you can cache both and vector data is actually less storage intensive, but at the same time pretty much every vector map implementation lags badly on my phone and sometimes even a bit on my netbook (Radar still lags for me, although less than Mapbox, probably because Mapbox does the whole fancy 3D globe thing with fog and stuff).
Either way, major props for making this exist and pricing it so competitively! Would be cool to also fix the attribution text that's on the lower right on desktop but doesn't show up on mobile, at least for me.
