About

Everything open data knows about an address.

nestcheck.ch brings together what the federal administration, the cantons and OpenStreetMap publish about an address: noise, public transport, taxes, buildings, energy, connectivity, natural hazards, nature, surroundings and the canton's rent benchmark. One input, twelve cards, 30 seconds. No account, nothing stored.
