https://grid.plus.codes/ shows grid generation working with different map providers, including free OpenStreetMaps (click "LEAFLET" or "OPENLAYERS").
Source code for the grid server is here: https://github.com/google/open-location-code/tree/main/tile_server Sample code to integrate with free map tile providers is here: https://github.com/google/open-location-code/blob/main/tile_server/example.html Neither requires any paid license or network connection to Google.
