## What it is
A community-curated awesome list of open-source transit software, GTFS/GTFS-Realtime tools, APIs, datasets, apps, and research. It serves as a discovery index for the public transportation open technology ecosystem.

## Use cases
- find GTFS libraries for parsing transit feeds
- discover tools to validate GTFS realtime data
- locate open datasets for transit research
- find apps that consume public transit APIs
- compare GTFS converters and analysis tools

## When to choose
- you need a starting point to explore the transit open-data ecosystem
- you want to discover GTFS tooling across many languages
- you're researching public transit data standards

## When to avoid
- you need a runnable library or application rather than a link list
- you need maintained, production-grade software itself

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation, data-science
- domain: awesome-lists, apis
- platform: cross-platform
- tags: awesome-list, gtfs, gtfs-realtime, public-transit, transit-data, curated-list, siri, open-data, maps, transportation, datasets
