JetBrains has announced a public preview of Fleet, its new IDE and lightweight code editor. JetBrains announced Fleet last November and attracted massive interest with over 137,000 people signing up for the private preview.

The JetBrains team says the aim of Fleet is to combine the best of a simple IDE and a lightweight code editor, to provide a tool that will be instantly available to handle simple tasks. Fleet has been created using the IntelliJ platform on the backend and a brand new UI and distributed architecture.

See it in action in this video:

If a developer finds they need more, there's a button that will then launch the IntelliJ IDE to get the full-blown editor with code-processing, project and context-aware code completion, navigation to definitions and usages, refactorings, on-the-fly code quality checks, and quick-fixes.

Fleet recognizes the type of project being edited, and has functions based on that, as well as supporting collaborative development. Remote development is also supported by launching the back-end in the cloud or on a remote server, meaning you can code without having to configure the local environment.

Languages supported in the initial version of Fleet are Java, Kotlin, Go, Python, Rust, and JavaScript. JetBrains plans to add support for other languages, with the existing set of IntelliJ-based IDEs providing an idea of what will be added.

The Fleet team says that while not all of the features of the main JetBrains IDEs will appear in it, they do want to hear developer feedback on things you feel Fleet is missing, such as specific refactoring options and tool integrations. 

Plans for future improvements that the team is already working on include API support and an SDK for plugin authors, and support for themes and keymaps. The team says they know developers feel more comfortable using the keyboard bindings and themes from their existing IDEs when they move to a new one. They also plan to add Vim emulation.
