What is Ghost Bus and what does it track?

A Dublin transit tool that watches the bus schedule against the live vehicle feed and surfaces trips that should be on the road but have no live vehicle reporting and no cancellation — the ghost buses apps still show as due.

The GitHub description says Ghost Bus asks it in plain English via Jev, and the README's stack line lists Jev / TypeSafe alongside FastAPI, Postgres, React and GTFS-Realtime.

What does it deliberately not claim?

It never claims a cause: a quietly cancelled bus and a bus with a broken GPS tracker look identical in the feed, so it reports only the observable fact 'scheduled, due, no vehicle'.

Where is Ghost Bus live and can I try it?

The app runs at ghost-bus-olive.vercel.app and the API at ghostbus-production.up.railway.app, per the README.

What is the technology stack behind it?

FastAPI on Railway, Postgres on Neon, Vite + React on Vercel, NTA GTFS-Realtime open data, and Jev / TypeSafe for the plain-English question.

Where did the project come from?

It was built in a day for Build for Ireland (Dogpatch Labs · OpenAI × Give(a)Go) during Dublin AI Week, per the README.

What license and status does it have?

The repository declares no license; it is Python, 1 star, created and pushed 2026-10-04. Accuracy and Jev configuration are not in the digest.

Watch out

README and GitHub metadata reviewed 2026-10-17; the digest cuts off inside the first of the three comparison questions, so the Jev question shapes, refresh cadence and any accuracy numbers are not captured. The README frames it as a telemetry-anomaly detector, not a verified no-show detector.
