Right on the website
it states they use the Weather Research

This is a relatively new model compared to GFS and ECMWF (and others) which are more commonly used.
Essentially these are all numerical forecasting models. As George Box stated - "all models are wrong; some are useful."
I'm not familiar with Theyr, but it looks like a Windy type clone, with ability to import
GRIB files and overlay them on navigational charts
