I can suggest several bits of client side rendering for OSM.
Pyrender is an on demand renderer written in python, serves tiles over
http (usually from localhost), aready has an OpenLayers config for it,
you'd probably just need to download the data beforehand -
Another alternative would be pre-rendering all the tiles beforehand,
storing them on the disk, then just pointing OpenLayers towards the
Both are fairly simple configs given an existing rendering setup.
