About CasaRadar

CasaRadar.io is a rental listing aggregation and alert service for the Barcelona housing market. We track the major and small listing websites in Barcelona, plus private WhatsApp and Facebook housing groups, and send you an alert the moment a new room or apartment matches your search criteria.

What we do

• Instant alerts by email, Telegram or push when a matching rental goes live, so you are one of the first to reply.
• Set your preferences once (location, budget, type) and receive only the listings that match.
• Access to 40+ private WhatsApp and Facebook housing groups where rooms and apartments are posted before they reach the public platforms.
• Option to exclude real-estate agents that charge additional fees.
• Free to start, then PRO from €19.95 per month (€39.90 every 2 months, or €29.95 monthly). Cancel anytime.
