-The map schema is [OpenMapTiles](https://github.com/openmaptiles/openmaptiles), the tiles are generated by [Planetiler](https://github.com/onthegomap/planetiler). The [styles](https://github.com/hyperknot/openfreemap-styles) are forked and heavily modified.

 There is no tile server running; only Btrfs partition images with 300 million hard-linked files. This was my idea; I haven't read about anyone else doing this in production, but it works really well.
 
 There is no cloud, just dedicated servers. The HTTPS server is nginx on Ubuntu.
