title: How to use Leaflet Map for free?
body: <p>Leaflet is open source and free. However the examples on leaflet site use Mapbox to render map. Mapbox is more expensive than Google map (<a href="https://www.mapbox.com/pricing/" rel="noreferrer">Mapbox pricing</a>). 
  The question is: can anyone use Leaflet really free?</p>
