zzd: Swiss everyday data

Answers everyday questions in Switzerland from the free sites zzd runs. No account or key is needed, and every tool only reads public data.

Grocery prices (Schnäppchen Jäger): search products across Migros, Coop, Lidl, Aldi, Denner and Volg, plus Aligro's weekly promotions, with pack price, price per unit and the date each price was read. For one product, see the identical article in other shops (matched by barcode) and the cheapest similar product per shop.

Civil wedding venues (Trauungslokale Schweiz): find places as cantons and municipalities publish them, by canton, town, number of guests or published date, with the responsible registry office.

Rents (Mietcheck): the usual net monthly rent by flat size in a canton, from the Federal Statistical Office, and whether a given rent is below, within or above that range.

Electric cars (EV cost comparison): cars offered in Switzerland ranked by total cost per km, across buying, importing, leasing and subscriptions. The offers are a dated, hand-collected snapshot.

Map posters (MappaMuse): the ready poster page for a Swiss town or place, with its sizes and prices in CHF.

Each answer names its source and date and links the page it came from. Prices are the shops' online prices, not shelf prices in a branch. Rents are cantonal averages, not legal advice. A published wedding date is not always a free one, and the date is always booked with the registry office. All Claude users share 300 grocery searches a day.
