Two years ago or so I started the OSM XRAY project, later I wrote about it in this blog post. Since then I have renamed this project to “OSM Spyglass” and I have kept working on it on and off.

This blog post is about the new OSM XRAY service. [Update April 2026: This service has since been renamed to Spyglass]. You can find a demo here. It uses vector tiles with all OSM data to really show all of OSM, mostly for debugging. But it is also interesting to just explore what’s there.
