Fleet is JetBrains' next-generation coding environment for macOS that starts as a blazing-fast text editor and grows into a full IDE the moment you need it — no project-load delay, no heavy setup, just open a file and go.
What is Fleet?
Fleet is a lightweight, smart coding tool from JetBrains that merges the instant-start feel of a modern text editor with the deep language intelligence that JetBrains is famous for in IntelliJ IDEA, PyCharm, and GoLand. You get a snappy, minimal interface by default; flip on Smart Mode for a specific file or folder and Fleet spins up a full language server with code completion, refactoring, inspections, and navigation — the same engine powering the full JetBrains suite, not a stripped-down version.
The architecture is deliberately distributed. The frontend, backend, and language services run as separate processes, which means Fleet can offload heavy analysis to a remote machine or a cloud dev environment without changing your local UI. That's a meaningful structural difference from VS Code or Nova, where the language server is tightly coupled to the editor process.
What does Fleet do best?
Fleet earns its keep on two things: near-instant startup and serious polyglot support. Where IntelliJ takes a minute to index a large project, Fleet opens in seconds and indexes lazily — you're typing before the spinner even appears. When Smart Mode activates, you get first-class support for Kotlin, Java, Python, JavaScript, TypeScript, Go, Rust, PHP, and more, all backed by the same analysis engines JetBrains has refined for over two decades.
The collaborative editing story is also worth mentioning. Fleet has multiplayer built into its core design rather than bolted on as a plugin — you can share a workspace and code with teammates in real time, with shared terminals and run configurations included. TextEdit-plus-screen-share this is not.
- Smart Mode on demand: toggle full IDE analysis per workspace, not globally — keep your other files snappy.
- Remote backends: point Fleet at a server or JetBrains Space dev environment and your Mac stays cool while the heavy lifting happens elsewhere.
- Unified multi-language workspace: open a monorepo with a Go API, a React frontend, and a Python ML script — Fleet handles all three in one window without separate IDE windows.
- Git integration: inline diff, commit, push, and branch management without leaving the editor.
How much does Fleet cost?
Fleet is free to download and use for personal projects. JetBrains has indicated that commercial licensing will eventually apply, but as of now the tool is available at no cost while it matures — an unusually generous position for software with this level of underlying engine investment. If you already subscribe to JetBrains All Products Pack or an individual product subscription, Fleet is included.
Who should use Fleet?
Fleet is the right tool for developers who feel torn between editors and IDEs. If you spend most of your day in VS Code but wish for IntelliJ-quality refactoring when things get complex, Fleet resolves that tension natively. It is particularly compelling for polyglot engineers — the kind of person who writes TypeScript in the morning, fixes a Python data pipeline at lunch, and reviews a Go service before dinner, all in one repo.
It's less ideal if you rely heavily on a specific IntelliJ plugin ecosystem that hasn't been ported yet. Fleet's plugin marketplace is still catching up to the depth of IntelliJ or VS Code's extension library, and power users of, say, database tools or Kubernetes tooling built into DataGrip or Rider may find gaps. For those workflows, a dedicated JetBrains IDE still wins.
What are the best Fleet alternatives?
The most direct comparison is VS Code — free, extensible, and the current default for most developers. VS Code's extension ecosystem is unmatched, but its language intelligence depends on third-party extensions of varying quality. Zed is the closest aesthetic match to Fleet — also fast, also built for collaboration — but its language support is narrower and it lacks JetBrains' analysis depth. Nova (Panic) is a beautifully native Mac editor with solid extension support, but it targets web developers specifically and doesn't offer the polyglot depth Fleet provides. For pure JetBrains users, a full IDE like IntelliJ IDEA or WebStorm remains the gold standard for project-specific power, at the cost of startup time and RAM.
How does Fleet compare to VS Code?
VS Code wins on extensions — there are tens of thousands of them, covering every niche from Terraform to obscure serialization formats. Fleet wins on language depth when Smart Mode is active; the analysis is more accurate, refactors are safer, and inspections catch subtler issues than most VS Code language server extensions manage. Fleet's distributed architecture also makes remote development feel more seamless than VS Code's SSH Remote extension, which can feel brittle on high-latency connections. For a solo developer on a well-supported language stack, Fleet is a genuine daily-driver alternative; for teams deeply invested in the VS Code extension ecosystem, switching carries real cost.
