Unlimited Reverse Geocoder?

Question

Geolocation

Good day.
I'm looking for a tool to determine the exact address by latitude and longitude. Ideally, it would be some kind of solution that you can download, put on your server and use without restrictions, sending latitude and longitude, and receiving JSON responses in response. Perhaps there are some databases that can be downloaded? I'm looking for an independent option so that I can use it without restrictions.
Thanks to.

Answer 1

Nobody bothers to get the latitude and longitude through the client and cache it via a POST request. That is, reverse geocoding - will be performed by the users themselves, and not by your server. You will only save the result that Google returned to them.
So gradually accumulate your base.
UPD: Another option (open-source): reversegeocode
