Open-meteo does have ECMWF data and forecasts. Free for non-commercial use. I think the person behind open-meteo is on HN.

You rang ;-) I’m in the middle of adding more ECMWF data that will be released as open data starting October 1st. At the moment, only a limited set of lower-resolution (0.25°) ECMWF forecasts can be shared open-data. That’s going to change in a big way, though I can’t share more details just yet.

Very happy Open Meteo campers for that, but meant something like Open Meteo for real-time lightning data.
