Why this scraper?

🎯 Built for Switzerland

A dedicated Swiss scraper, not a global tool with a country dropdown. Price handling, room counts and location matching follow how comparis.ch actually publishes listings, in CHF.

🏘️ Every property type

Apartments, houses, flatshare rooms, furnished apartments, land plots and holiday properties — rent or buy, in one input.

📄 Complete listing data

Title, full description, price and price type, rooms, living area, floor and year built, plus every photo published on the listing.

📍 Precise location

Street, street number, postal code and city, with latitude and longitude taken from the listing's own map position.

🔎 Server-side filters

City or canton, price range, room range and listing age are applied at the source, so you retrieve only what you asked for.

🔗 Direct URL mode

Paste comparis.ch search result URLs and the scraper follows them exactly, filters and all.

Performance

Run size	Typical time
20 results with details	under 1 minute
100 results with details	2–3 minutes
1,000 results with details	20–30 minutes

Turning fetchDetails off returns roughly ten times as many listings in the same time, with the list-level fields only.

Known limitations

• Living area, year built and floor are frequently not published by the advertiser, especially on rental listings. These fields return null rather than a guess.
• A single search returns at most 1,000 listings. Split larger jobs by city, price band or property type.
• Very large runs can stop short of the requested maxItems when the source throttles sustained traffic. The run still finishes successfully with the listings it collected; re-running picks up the rest.
• Descriptions are in the language the advertiser used — German, French or Italian depending on the region.
• Advertiser contact names, phone numbers and email addresses are never returned.

---

Technical details

• Source: comparis.ch — Swiss property marketplace, rentals and sales
• Coverage: nationwide, filterable by city or canton, price, rooms and listing age
• Memory: 256 MB
• Retry: automatic retry on rejected and failed requests, with a fresh identity per attempt and an automatic fallback route when the source throttles
