“Danger here”: your town’s fire danger, on your website
A small box that any town council, mountain club, campsite or local paper can paste into its website. It shows today’s and tomorrow’s fire danger, what that number means in that place given the fires it has already had, and the nearby satellite hotspots. Free, no sign-up, with attribution and a link to worldfires.org.
How it looks on your site
This is the real widget with today’s data. Tap “Today” or “Tomorrow” inside it, and the “i” for sources and method.
Sapucai Paraguarí, Paraguay

What the widget says
Loading…
The colour is the EFFIS class: the same FWI scale for the whole world.
The second line is what nobody else gives: where the forecast FWI falls among the FWI at which the real fires of that municipality started (or of its region, if it has few). A “low” FWI at which half of the local fires already started deserves attention.
It is a comparison with the past, not an alert. The widget footer always says “Not the official warning” and links to the country’s official service.
On your phone’s home screen
The same widget, full screen: today and the coming days, the hotspots around and the official warnings one tap away. It keeps the last reading so you can see it without signal, with its time.
- Open it on your phone with the button below.
- In the browser menu, choose “Add to Home screen” (on iPhone, from Share).
No notifications, no accounts: it is a web page saved as an app.

- Limit: 2 requests per second per IP, with bursts of up to 10.
- Responses are valid for 15 minutes: store them instead of asking again. For a point, the forecast is that of its 0.25° cell.
