Why this scraper?

🎯 Built for Switzerland

A dedicated Swiss scraper, not a global tool with a country dropdown. Locations, price formats and currency (CHF) are tuned for comparis.ch.

🏠 Property characteristics

Bedrooms, rooms, surface and property type in structured fields, ready for filtering and analysis.

📄 Full listing content

Complete listing description and title for every record, with a direct link back to the source.

📍 Precise location

Address fields plus latitude/longitude for mapping and radius analysis.

🔁 Repost & change detection

Every record carries isRepost and changeStatus, so daily feeds return genuinely new listings instead of reposted duplicates.

Known limitations

• Some fields (surface, year built, energy label) are only returned when the lister publishes them — expect null on a share of records.
• Listing photos and agent details vary per listing; the scraper returns what the source publishes and never invents data.
• Very large result sets are bounded by the source's own paging limits.
• Listings can be withdrawn at any time, so a small share of URLs may expire shortly after scraping.

Technical details

• Source: comparis.ch — Switzerland property listings
• Coverage: everything the public search exposes, filterable via the input parameters above
