JetBrains is popularly known for the development of multiple IDEs that cater to a number of development niches such as web, Android, and data science.
Recently, JetBrains released a preview of the newest tool in its IDE arsenal, JetBrains Fleet–a multi-language programming IDE. JetBrains Fleet has been designed to be a lightweight IDE that supports multiple languages and features.
These characteristics make Fleet a new contender in an IDE world popularly dominated by VS Code. But what are its key features, and how does it compare to VS Code?
JetBrains Fleet’s System Architecture Design
JetBrains Fleet is mainly written in Kotlin on top of a JVM platform. This is because of the performance and the cross-platform nature associated with JVMs allowing support for multiple operating systems.

The IDE utilizes a distributed architecture design that supports local standalone instances, remote development, and collaborative development environments. This is made possible by a number of components:
Frontend Component: This component serves the UI, launches the fleet in the default editor mode, parses files, and performs limited syntax highlighting and basic code completion. Workspace: The workspace component handles a user’s working sessions. It manages the different running states. State management functionality is run as a process within Fleet or as a different process depending on whether you are running Fleet locally or in a remote workstation. Backend Component: The backend component is a decoupled service that is responsible for indexing, navigation, and static analysis. The service processes request sent by the workspace and sends responses to the target components. Fleet System Daemon (FSD): FSD is written in Rust. This component is responsible for executing the commands on the terminal, running code, and build actions.
