Immoweb Data Parser & API

Immoweb is Belgium’s #1 property portal — around ~5.75M monthly visits and the largest Belgian listing pool — and PropAPIS extracts its resale, rental, and new-build listings through a single REST API. Owned by the Aviv Group, Immoweb belongs to the same portal family as France’s SeLoger, so a shared parser strategy spans both markets.

Platform Overview

Market Position

Immoweb is the clear market leader in Belgium, carrying the largest national inventory and an estimated ~5.75M monthly visits (Apr’26) (Semrush ). It is owned by the Aviv Group — the Axel Springer real-estate vehicle, majority-owned by KKR with CPP Investments — placing it alongside SeLoger, Immowelt, and Immonet in one connected portal cluster.

• Belgium’s #1 Portal: The dominant property destination nationwide
• ~5.75M Monthly Visits: Leading reach across the Belgian market
• Aviv Group Family: PropAPIS covers the wider Aviv portal cluster
• Bilingual Market: Dutch (Flanders) and French (Wallonia/Brussels) listings

Immoweb’s owner, Aviv Group, operates a cluster of portals across Europe that PropAPIS covers as a connected family:

• Belgium: Immoweb
• France: SeLoger, Logic-Immo, Meilleurs Agents
• Germany: Immowelt, Immonet
• Austria: Immowelt.at, ImmoScout24.at

A single parser strategy can span much of this cluster thanks to shared technology and data pools.
