Your weather. Your station. Your computer.

Free, open source, and built to work even when the internet does not. No cloud. No account. No subscription.

Why this exists

Most weather apps lock you into a service. Open Weather is the other path: self-reliance. Build a station from parts you can buy and print, run the software on your own computer, and keep a live picture of the weather right where you are.

Build it yourself Stations from common hardware, 3D-printed parts, and open firmware.

Keep it local Readings stay on your machine. There is no Open Weather server.

Stay useful offline Monitor hyper-local weather with no connection.

Use the public record When the internet is up, fill in radar, satellite, alerts, and a 10-day outlook from free sources.

What you get today

The Command Center is the desktop app for Windows, macOS, and Linux. Connect a home station when you have one. Until then, the map and outlook still work from public sources.

A dashboard for live conditions at your pin
High-resolution weather radar from NOAA NEXRAD
GOES satellite pictures from NOAA
Weather alerts from the National Weather Service (NWS)
A 10-day outlook that blends free public models through Open-Meteo, plus NWS / NOAA guidance

Local first. Internet optional.

You have…	Open Weather can…
A station, no internet	Show live local readings and keep history on your computer
Internet, no station	Show radar, satellite, alerts, and the 10-day outlook
Both	Combine your backyard numbers with the national picture

We do not upload your location history, station data, or personal information. Sharing, when it arrives, will stay anonymous.

Build a station

The long-term goal is a station anyone can make:

Parts that are easy to find
3D-printed housings and mounts
Open firmware you can flash and change
Software that talks to the station on your own network

Hardware and print files are still coming back into this project. Outdoor print notes are in Issue #1 and the filament spreadsheet.

Sharing, later — still private

On the roadmap is a network of home stations that can fill gaps for neighbors and for the outlook. Stations will be able to share readings over the internet, LoRa mesh, and similar links. No names, no accounts, no household data — only weather. That network is not built yet. The app is designed so it never has to depend on it.
