Well this "extension" is closed source, but at the core we use deck.gl [0]. deck.gl is under open governance [1] inside the Linux Foundation/Urban Computing Foundation, so no contributor can take the project closed source.

I thought deck was based on mapbox.gl, which has now gone closed source.

No, this is a common misconception about deck.gl. deck.gl is completely independent from other frameworks, however deck.gl is more geared towards data visualization, so it's commonly paired with other frameworks that focus on a vector basemap.

There are examples [0] of pairing deck.gl with either Mapbox GL JS or Google Maps. It's also easy to use deck.gl with the open source Mapbox GL JS port [1]. Also if you're ok with a bitmap basemap, you can just render OSM tiles with deck.gl directly [2].

(Also I guess good to disclaim that I'm a maintainer of deck.gl )
