Free Google reverse geocoding
Don't know if anyone on Traccar forums tried this, but from the article it says only about geocoding, not reverse.
But implementing it in Traccar is also another technical feat.
Any thoughts Anton?
I believe it should work with any Google API.
Recently found this article if anyone wants to try it:

I'm not sure about legality of this solution, so do it at your own risk.
