In its own words
The project's README opens: "Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding). An instance with up-to-date data can be found at https://nominatim.openstreetmap.org. Nominatim is also used as one of the sources for the Search box on the OpenStreetMap home page."
Why it ranks here
Health score explained
Nominatim scores 85/100, #11 of 20 in Maps and Global Positioning System (GPS): 115 commits in the last 90 days earn 35.0 of 35 points, the latest release (v5.3.3, 16 days ago) earns 25.0 of 25, 4,542 stars add 14.6 of 20, an active, unarchived repository keeps 10 and no advertised Docker image leaves the final 10 unclaimed. That places it in the good band (70 and above). The biggest shortfall is Docker support, worth 10.0 more points.
