Features:
<ul>
<li>No API key required – uses OpenStreetMap tiles</li>
<li>Simple shortcode embedding</li>
<li>Address geocoding via Nominatim</li>
<li>Custom marker titles with popups</li>
<li>Multiple tile providers (OpenStreetMap, CartoDB Light, CartoDB Dark)</li>
<li>Responsive design for all devices</li>
<li>Configurable zoom levels</li>
<li>Enable/disable scroll wheel zoom</li>
<li>Gutenberg block support</li>
<li>Lightweight and fast loading</li>
</ul>
<h3>Usage</h3>
Basic Shortcode:
<pre><code>[mbyg_map address="1600 Pennsylvania Avenue, Washington, DC"]

</code></pre>
Using Coordinates:
<pre><code>[mbyg_map lat="51.5074" lng="-0.1278" title="London" zoom="12"]

<li><code>height</code> – Map height in pixels (default: 400)</li>
<li><code>title</code> – Text shown in marker popup</li>
<li><code>provider</code> – Tile provider: openstreetmap, cartodb-light, cartodb-dark (default: openstreetmap)</li>

<h3>External Services</h3>
This plugin relies on the following third-party services to provide map functionality:
<h4>OpenStreetMap Tile Servers</h4>
This plugin displays maps using tile images from OpenStreetMap’s tile servers. Map tiles are loaded when a map is displayed on your website.
<ul>
<li>What it does: Provides the visual map tiles (the actual map images you see)</li>
<li>When data is sent: Every time a map is displayed on your site</li>
<li>What is sent: The geographic coordinates (latitude/longitude) and zoom level to determine which map tiles to load</li>
<li>Service provider: OpenStreetMap Foundation</li>
<li>Terms of Use: https://wiki.osmfoundation.org/wiki/Terms_of_Use</li>
<li>Privacy Policy: https://wiki.osmfoundation.org/wiki/Privacy_Policy</li>
<li>Tile Usage Policy: https://operations.osmfoundation.org/policies/tiles/</li>
</ul>
<h4>CartoDB/CARTO Tile Servers (Optional)</h4>
If you choose the CartoDB Light or CartoDB Dark tile providers, map tiles are loaded from CARTO’s servers instead.
<ul>
<li>What it does: Provides alternative styled map tiles</li>
<li>When data is sent: Only when CartoDB tile providers are selected</li>
<li>What is sent: Geographic coordinates and zoom level</li>
<li>Service provider: CARTO</li>
<li>Terms of Service: https://carto.com/legal/</li>
<li>Privacy Policy: https://carto.com/privacy/</li>
</ul>
<h4>Nominatim Geocoding Service</h4>
When you provide an address (instead of coordinates), this plugin uses the Nominatim geocoding service to convert the address to geographic coordinates.
<ul>
<li>What it does: Converts street addresses to latitude/longitude coordinates</li>
<li>When data is sent: Only when an address is provided in the shortcode (not when using lat/lng coordinates directly)</li>
<li>What is sent: The address text you specify in the shortcode</li>
<li>Data caching: Geocoded results are cached for 24 hours to reduce API calls</li>
<li>Service provider: OpenStreetMap Foundation</li>
<li>Terms of Use: https://operations.osmfoundation.org/policies/nominatim/</li>
<li>Privacy Policy: https://wiki.osmfoundation.org/wiki/Privacy_Policy</li>
</ul>
Note: If you prefer not to use the geocoding service, you can always provide latitude and longitude coordinates directly using the <code>lat</code> and <code>lng</code> shortcode attributes.

Maps by G

Display addresses on beautiful, interactive maps using OpenStreetMap. An open-source alternative to Google Maps that requires no API key.

Takashi KOIKE

Embed OpenStreetMap on the page/post using [embed_osm] shortcode.
<ul>
<li>Shortcode generator metabox will appear on the page/post edit pages.</li>
<li>Drug and zoom the map on the metabox, shortcode will be automatically generated.</li>
<li>Copy generated shortcode and paste to the page/post editor.</li>
</ul>
On the plugin setting page, you can specify home position, size of map, type of marker and so on.
You can specify map layer via shortcode and plugin setting page. 
Map layer seleced by shortcode is higher priority than plugin setting.
