New to GTFS·X? Start here

Welcome 👋 A few quick answers to get you going:

Is it free? The editor is free forever — build, validate, and export a GTFS .zip with no account. Paid plans (Pro, Agency) add hosted publishing at a stable URL, snapshot history, embeds, and the planning/analysis tools.

Can I import an existing feed? Yes — drag a GTFS .zip into the editor. We parse routes, stops, calendars, shapes, and fares.

Does GTFS-Flex work? Yes — polygon zones, booking rules, and stop groups, alongside fixed-route.

My feed has validation errors. The validator runs continuously as you edit; click any issue to jump to it. Clear structural/reference errors before exporting so the Mobility Database doesn't reject the feed.

How do I publish? Pro and up gives you a hosted, canonical feed URL (skip the SFTP), snapshot history, and one-click Mobility Database submission.
