Why I built a real-estate tool with zero real-estate listings

Every property site in Korea (Hogang-no-no, Zigbang, Dabang) shows the same listings with the same agents.

What people actually need when moving:

• How far is the subway? (door to platform)
• Can my kid walk to school?
• Is there a mart within 10 min on foot?
• How long to my workplace, with transfers?

That's what I built: https://geoinfomatic.pythonanywhere.com?ref=devto&utm_source=devto&utm_medium=social&utm_campaign=multi-site-bot

No listings. No agents. Just an honest accessibility map.
