BORIS-D

BORIS-D is a collaborative project among multiple German federal states designed to provide standardized land value data through a web-based platform. This Chrome extension offers easy and free access to general information on property markets in Germany, aggregating data from expert committees responsible for setting land reference values. While official and detailed data remain on respective state portals, BORIS-D helps users cross-reference property values uniformly across borders. The extension complements the official BORIS-D website and is currently available exclusively in German.
