Not great. :-(

Nominatim effectively only has 1 maintainer / primary contributor:
lonvia spends a significant amount of her volunteered time defending
the service again abusers.
Single users can overload nominatim by sending 1000s of automated
requests per second, the same holds true for the tile servers we run:

Nearly as bad contribution wise is the server infrastructure code:

What we badly need is more help from developers and chef operations people.

How about someone in the community organises a Beauty Parade / Cross
Comparison of different open OpenStreetMap GeoCoders?

The OpenStreetMap Operations team prefers to be able to self-host the
infrastructure required to run OpenStreetMap.org. Reasons: Privacy /
Maintainability / Availability. We don't go this route for a
navigation / router as they seem to be under constant flux, without a
clear "winner" and system their requirements keep climbing.

Kind regards,
