InfraNode vs Umeå Open Data

InfraNode unifies open data for dozens of German cities into a single versioned REST API, covering weather, air quality, EV charging, public-transit departures, demographics, and dozens of other civic datasets. Every endpoint is keyless and rate-limited per IP rather than gated behind a subscription ("Die API ist offen und braucht keinen API-Key"), with an OpenAPI spec and Postman collection published for quick integration. The project is open source (Apache-2.0) and runs on a server in Germany with no ads.

Umeå's open-data portal runs on the OpenDataSoft platform, publishing the Swedish city's GIS, transit, and municipal datasets through the standard ODS Explore v2.1 API. Every dataset can be queried, filtered, and exported as JSON, CSV, or GeoJSON with no authentication required for public data.
