JetBrains invites developers to join the Fleet Public Preview Program

I think, correct me if I am wrong, Fleet is written in Kotlin, hence running on top of JVM. ( I am assuming Kotlin Native not being used yet )

While I dont think VSCode is fast and lean when compared to Sublime or other Native Editor. It is well optimised.

I do wonder if Fleet could catch up or even exceed VSC in the performance / resources usage department.

It totally could, the JVM is really fast. JS interpreters are fast too these days. So I don't expect much difference between the two.

One department where the JVM may win is latency (the new GCs are incredibly fast so no impact there) for typing to display.

Other than that I don't expect much difference.

Fleet, like the other JetBrains IDEs is indeed running on the JVM.

It also has some components in Rust and a special GUI framework.

There is a great series of blog posts about its architecture and design here with a lot of details:
