Serenum is a Swedish-based weather service that puts you in control of your own data and adapts to your choices.

Open source and self-hosting

Unlike many other weather services, you can see how Serenum is built from the inside (the source code). If you want and can help make Serenum better, please do.

If you have your own web server, you can install Serenum and use the service either fully locally (without CDN) or partially locally (with CDN).
