By default, Algolia Places only supports up to street level precision, which is why you may see a discrepancy between the geolocation returned by Algolia Places and GoogleMaps.
However, we have recently implemented a house-level precision solution for France (and only for France). This solution is an opt-in beta, and if you want, we can add your application to the list of participants. The community website is one of the applications that is part of that opt-in beta, which is why you see a difference in results with your application.
However, note that the house level precision will only be for France, other countries will still be limited to street-level precision. If your use case is restricted to France, we’d be glad to onboard you.
