Game engine maker Unity has launched a developer program to help its users build experiences to run on the forthcoming Apple Vision Pro.

Namely, Unity’s WebGL deployment support will be free of charge for both free and Pro users. You’ll be able to build a game in Unity’s engine and push it to the web without paying them a dime.

Following Unity’s pricing gaffe, GameMaker is making its engine free for non-commercial use, and switching its professional license to a one-time, $99 fee.

The goodwill that game engine developer Unity burnt over the last week with its bizarre and retroactive pricing demands are going to be a problem for not just the iPhone, but Apple Vision Pro too.
