Kranli helps building trades in Switzerland follow construction publications near their workshop. Choose a municipality, a radius and a trade to receive a morning email selection, with links to the official sources. Coverage varies by canton and source; a publication does not confirm a construction start or an available contract. Personal alerts cost CHF 19/month or CHF 190/year, with a seven-day trial without a card. Public pages, an aggregate barometer and a read-only API are available separately without an account.
