But is it rewritten in Rust?

It’s funny because, I’m probably the minority, but I strongly prefer JetBrains IDEs.

Which ironically are much more “walled gardens”: closed-source and subscription-based, with only a limited subset of parts and plugins open-source. But JetBrains has a good track record of not enshittifying and, because you actually pay for their product, they can make a profitable business off not doing so.
