What Strado is
A scoring tool for European neighborhoods. Type an address, see how the street around it ranks across 22 categories: groceries, transit, parks, healthcare, nightlife, dining, cycling, and more. All data is public, sourced from OpenStreetMap and EU open data portals. No reviews. No sponsored listings.
50 cities so far, 28 countries. More coming.
Why I built it
Walk Score covers the US behind a paywalled API. European real estate portals stop at their own country's borders. Nothing freely available scored multiple European cities the same way.
So I built one. Same scoring logic for Lisbon, Helsinki, Rome, and Warsaw. Same data sources. Same hexagonal grid. Same letter grades.
How it works
OpenStreetMap data and EU open data portals feed a Python pipeline into PostgreSQL with PostGIS. About 690 million rows at last count, across 19 tables. Scoring runs live on an H3 hexagonal grid at resolution 9, so each hex covers roughly 0.1 km2 (174 meters edge to edge).

Who's behind it
Strado is a one-person project built under FlxCode. Not a company, not a startup.
No VC funding. Analytics are anonymized via self-hosted Umami. A Google Ads conversion tag is loaded for a small paid campaign. The tool itself is free. Data is under the OpenStreetMap license (ODbL).
