As a solution in between, for those who want to include a OSM map on their website but don't want to put load on the official OSM tile servers, a simple tile proxy may be a good idea.

I am using something based on https://wiki.openstreetmap.org/wiki/ProxySimplePHP5 for a long time already and since I don't need to have up to date tiles every day, I set the TTL to a few weeks.

Together with leaflet this works beautifully.
