Awesome Transit: Curated Directory of GTFS Tools and Transit APIs

MobilityData maintains this curated repository of transit-related APIs, software, and datasets, with the most recent update recorded in January 2026. It serves as a central directory for the transit community, focusing heavily on General Transit Feed Specification (GTFS) tools and real-time data resources.

Use Cases

• Locating GTFS-validator tools to ensure transit schedule data meets industry standards
• Finding transit-agencies feeds for use in urban mobility and routing applications
• Identifying GTFS-converters to transform proprietary transit formats into open standards

Strengths

• Curated by MobilityData, the organization responsible for transit data standards
• Categorizes resources into specific technical niches like GTFS-realtime and GTFS-validators
• Released under a CC0-1.0 license for maximum accessibility

Limitations

• Does not host raw data directly, acting instead as a directory of external links
• Link persistence is subject to the uptime of third-party websites and repositories
