OpenDataPhilly

  • A catalog of open datasets from the City and regional organizations.
  • Publishes raw files — CSVs, shapefiles, APIs.
  • The authoritative source of record for Philadelphia public data.
  • Not designed to answer a specific question directly.

ALKARTIS

  • Connects multiple OpenDataPhilly datasets into one searchable layer.
  • Cleans, joins, and cross-references records automatically.
  • Every figure still traces back to the original public source.
  • Answers a specific question — not just links to a file.

OpenDataPhilly is where the data lives. ALKARTIS is what happens when someone actually needs an answer from it, not just a download link.

Frequently asked questions
Does ALKARTIS replace OpenDataPhilly?
No — we build on top of it and always credit it as the source. See our Terms for how we handle underlying data rights.
Why not just use OpenDataPhilly directly?
You can — for many purposes, the raw catalog is exactly what you need. ALKARTIS exists for the moment you need a connected answer, not just a file.
