Prio vs CasaRadar vs Idealista alerts: what each covers
We build Prio, so we have a stake here. This page compares the three options people weigh most often for new-listing alerts in Spain, and says where each one fits. The only speed figure is the one Prio can stand behind: at least 2 minutes ahead of Idealista push notifications.

Prio vs CasaRadar: speed on Idealista or breadth across sites
CasaRadar is an aggregator focused on Barcelona: according to its own site it pulls listings from most of the major rental platforms into one search, with updates by email or WhatsApp. Its strength is breadth. Prio does not list homes or cover Fotocasa and the smaller portals: it sends each new Idealista listing that matches your search to Telegram at least 2 minutes ahead of Idealista push notifications, plus rooms from Badi, each alert ready to act on with the phone number when the listing shows one and a pre-written WhatsApp message.
Are Idealista's own alerts enough?
For a relaxed search in a quiet town, yes: saved searches are free and notify you in the app or by email. In a busy market such as Barcelona, where the average rental ad gets 54 contacts (Idealista 2024 annual report, via Barcelona Secreta), an alert that reaches you sooner can matter, and native alerts cover Idealista only.
Which should you choose?
- Choose Prio if you want to be among the first on new Idealista listings, with contact details in the alert.
- Choose an aggregator like CasaRadar if you prefer one feed across several sites and Barcelona is your only city.
- Rely on native Idealista alerts for low-competition searches where being second or third does not cost you the flat.
Whichever you choose, check each listing before you pay: paste the Idealista link in the listing checker.
