RainViewer started as a small project and grow out into a service that provides a single map with over 1000 weather radars. All the data coming from the radars, RainViewer displays on the map: rain and snow animation, precipitation intensity, storm path. This makes it super convenient to observe and monitor doppler radar animations over the world. RainViewer map has the biggest radar coverage in the market, which means that you won’t find a map with over 1000 rain radars in open access.

For years RainViewer API and map were free of charge and, of course, continue to be free in open access. During these years, we saw over 60 weather web portals and about 10 weather applications that were using RainViewer map or API to provide information about the rain to their end-users.

We’ve been asked numerous times about the possibility to donate or make a contribution to our service. It’s obvious that API support requires additional resources, time and investment. Our goal is to continue delivering a high-quality product. Therefore, we created a possibility for you to make a donation to RainViewer on Patreon: https://www.patreon.com/rainviewer

What does it mean? If you’re using RainViewer API for a commercial project, you’re more than welcome to make a donation in order to support RainViewer API that generates revenue for your company.

If you are a non-profit project using RainViewer API or embedded map, you are more than welcome to support RainViewer project spreading a word about it on social media: Twitter, Facebook, Snapchat.
