The Fleet’s “commercial part” is related to IDEA’s paid features. But IDEA has the “community edition” which is fully open. Eventually, that part of functionality should be available in the Fleet somehow.

Another “paid part” is related with cloud features, but at some degree clouding may appear in a free form.

Also, Fleet works well with LSP and that functionality will be available freely.

JB owns Kotlin and people there know how to use it properly. Some resource-critical parts of the Fleet are made using Rust or call C-libs (Skia). But for the “domain logic” level Kotlin plays pretty well. (I was a part of the Fleet team, so I saw all the guts :)
