This is a comprehensive list of API endpoints, libraries, apps, tools and resources for accessing public transportation data in the Verkehrsverbund Oberelbe (VVO) network, which includes the Dresdner Verkehrsbetriebe (DVB).

This repository serves as the primary community resource for Dresden transit API documentation, containing reverse-engineered specifications, links to client libraries, and a comprehensive ecosystem overview.

This document is inspired by derhuerst/vbb-modules.
