ootb-openstreetmap
A map block for WordPress' Gutenberg Editor which uses OpenStreetMap and Leaflet.js. It needs no API keys and works out of the box. Benefiting from Gutenberg’s potential, the plugin tries a different take on how to add your locations on the map and rethinks a few things, UX-wise. Install it from https://wordpress.org/plugins/ootb-openstreetmap/
