OSM/Google Maps as Base Layer on Geoserver

Question

I want to make Google Maps or OpenStreetMap (OSM) a base map/layer on Geoserver that can be published, without having to download the entire map, for example by using the xyz tile url service like so:
Google Satellite : https://mt1.google.com/vt/lyrs=s&x={x}&y={y}&z={z}
or,
OSM : https://a.tile.openstreetmap.org/{z}/{x}/{y}.png

Is there any solution regarding this problem?

Answer 1

GeoServer only provides the capability to cascade WMS, WMTS and WFS services. It would be possible to write similar code to cascade OSM tiles but I would expect this would violate the Google ToS (iirc you must not scrape their tiles).

I think MapProxy can do what you ask for, at least for OSM tiles.
