An OpenWeatherMap alternative with maps, air and rivers

OpenWeather is the weather API most developers try first. If your app also needs map data, air quality, river levels or the weather along a route, this is how the two compare, from OpenWeather's own pricing page as it read on 8 November 2026.

Which one fits

If you show the current weather and a five-day outlook to many users and nothing else, OpenWeather's free plan gives more calls than ours. If you need weather history or ready weather map tiles, OpenWeather has them and we do not.

Running Cat Geo API fits apps that ask several things about the same place or route: the hourly forecast from ECMWF, NOAA, DWD and Canadian models, the weather at each point of a ride, air quality and pollen, river levels, heights, routes and OpenStreetMap data, on one key and one bill. GET /v1/point returns most of that for a place in a single request.

The free plan gives 500 requests a day, for commercial apps too. Create an account with Google or your email and make your keys right away.
