Host your own OpenStreetMap Map Tiles

The highest zoom levels are generally generated on demand, as there’s so many tiles.

Zoom level 20 is over a trillion tiles, most of them worthless blue sea tiles. We’re probably talking hundreds of terabytes just for the file system metadata, to say nothing of the tiles themselves.

Of course, you could forego the ability to zoom in very far.

With vector tiles you don't need to generate up to z20 - just to z14 is enough, and that can easily be done in a single .mbtiles (which is an SQLite database of vector tiles).
