bytiq.cz pulls property listings from all the major Czech real-estate portals into a single, queryable analytical view.
I built it for myself. A partner and I were actively investing and wanted to rank offers by our parameters — above all price per m² against the neighborhood average — instead of whatever order each portal happened to show. No existing tool sliced the market that way, and the data was scattered across portals that never compare against each other.
- Scraping: Node.js scrapers across the major Czech property-listing platforms.
- Application data: PostgreSQL.
- Analytics: Snowflake on top, powering the analytical layer.
It's the personal version of a pattern I keep applying at work: scrape disparate external sources, normalize them, and surface the result as a queryable analytical layer with a usable UX on top. In active use since 2025.
