I can easily do this for North America using imagery here, for example: https://www.star.nesdis.noaa.gov/GOES/conus.php?sat=G16 (bonus, imagery is Public Domain).
This direct link provides an updated image every five minutes, with even higher resolution available if you like: https://cdn.star.nesdis.noaa.gov/GOES19/ABI/CONUS/GEOCOLOR/2...
Every time I revisit this idea and look for western Europe, I find nothing. Or, very low resolution, or some clunky, proprietary "viewer" forced on users. Is there really nothing similar for Europe?
Sentiel-2 data can be pulled for free from the Copernicus service. It's a LEO sat and you often get a picture every 2 days of the same region.
DWD (German Meteo Service) offers a metric ton of data on their FTP Server as public data.

While doing that, I learned that it is not so trivial to produce a true colour RGB image from these FCI [1]. I think there is also a WMS server for rendered images but I don't have the link on my phone.
I feel like an idiot, I can't figure out how to enable it. Currently I use https://www.firemap.live/ for tracking local wildfires (which isn't something I ever needed to track, prior to this year)
In Eastern Ukraine i also see sat trackers detect a lot, which is obviously mostly not wildfires.
