Hi, I'm Tacettin 👋

I build GTFS City — a free, open-source tool that brings transit data to life.

What is GTFS City?
Upload any city's GTFS file and instantly visualize routes, stops, and vehicles on an interactive map. Run simulations, analyze coverage gaps, detect vehicle bunching, and plan routes — all in your browser,
no installation needed.

Why I build this:
Public transit data should be accessible to everyone — city planners, researchers, transit enthusiasts, and citizens who want to understand their city better. Commercial tools are expensive. I believe this
should be free.

Your support helps me:

• Keep the tool free and ad-free forever
• Add new analysis features
• Maintain and improve performance
• Cover hosting costs

Every contribution, big or small, keeps this project alive. Thank you! 🚌
