👋 Hi Product Hunt! I'm Ayokaf, the maker behind RefCatastral.es.

The Problem: If you've ever dealt with real estate data, architecture planning, or property investment in Spain, you know the pain. You have to navigate fragmented government websites, rely on digital certificates that constantly crash, and fill out endless forms just to check a single cadastral reference.

The Inspiration: I decided to build the tool I desperately wished existed for my own day-to-day work. I wanted something as fast and intuitive as a modern search engine, but for complex public data.

How it evolved: We started by unifying the standard National Cadastre, but our approach completely evolved when we realized the real data "black hole" was in the independent regional tax agencies (Haciendas Forales). We rebuilt our backend using a highly optimized SQLite architecture to successfully integrate 100% of the territory—including the notoriously difficult regions of Navarra, Bizkaia, Gipuzkoa, and Álava—into one single interface.

✨ Key Features:

Zero Forms & Zero Logins: Just type an address and get the data.

100% Coverage: State data + all Foral regions.

Instant Speeds: Powered by our custom SQLite engine.

Privacy First: No personal data tracking to run a search.

🎯 Test our speed!
If you want to see our database handle the most complex regional integrations in milliseconds, try these direct links:

📍 Gipuzkoa: https://refcatastra l.es/gipuzkoa/

I’d love to hear your thoughts, feedback, or any feature requests you might have. I'll be hanging out here all day answering your questions!

Cheers! 🚀
