Show HN: Sightline – Shodan-style search for real-world infra using OSM Data

I built *Sightline*, a Shodan-style search engine for *physical-world infrastructure*.

Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real world, using OpenStreetMap as the data source.

You can search things like:

* “telecom towers in karnataka” * “power plants near mumbai” * “data centers in paris france”

or use structured queries:

* `type:telecom operator:airtel region:karnataka` * `type:data_center operator:google`

Sightline:

* uses Overpass API for querying OSM features * uses Nominatim for resolving countries, regions, and cities * avoids hardcoded geography * uses deterministic, rule-based parsing (no AI inference)
