Might not be what you are looking for but https://wiki.openstreetmap.org/wiki/Nominatim is a geocoder that runs on OSM data.

Pelias (and Mapzen Search) is so much better: http://pelias.io/

Thanks for sharing. Geocode and RevGeo are generally considered a Hard Problem (TM) in GIS so it is nice to see great projects such as this.

Hi,

I'm one of the makers of the OpenCage Geocoder: https://geocoder.opencagedata.com

We provide a single, simple API that behind the scenes aggregates numerous open geocoders, including nominatim, DSTK, and others. Please give us a try, there is a free testing tier you can use as long as you like.
