There's also https://www.predictwind.com/ which is a (very expensive) commercial service a lot of boat/yacht folks use for planning. I believe they also have some utilities for delivering compressed forecast data over satellite link as well.
Their premium tier is for automatic routing and can get expensive for budget sailors.
This stuff really only applies to offshore or other low bandwidth connection use cases. When I have decent cell/internet it’s hard to beat windy’s UI.
