OpenConditions

The live layer OpenStreetMap doesn't cover

OpenConditions is an open, self-hostable commons for what changes by the minute —
road incidents, closures, roadworks, and congestion — live in OpenMapX today, with transit, places, and crowd reports on the roadmap.

Complements OpenStreetMap, doesn't replace it

OpenStreetMap maps what's permanent. OpenConditions covers what isn't — incidents, closures, and congestion now, with transit occupancy, place busyness, and crowd reports next. We never write back to OSM; we just point at it.

Open source, standards-first

OpenConditions speaks DATEX II, GTFS-RT, TraFF, Open511, and WZDx — no invented format, no new identifier scheme. Star it on GitHub, self-host it on your own server, or follow along on the blog.
