Choosing a Go IDE: GoLand, VS Code, and why to leave the Web IDE

1. Why you need a local IDE after a Web IDE

If a Web IDE is like a single-speed bicycle, a local IDE is a bike with proper brakes, a flashlight, a pump, and a clear map. Yes, you can ride without all of this. But as soon as you have more than one or two tasks, your brain starts spending energy not on programming, but on "where is my file?", "why won't it run?", and "did I really save the changes?".

In a Web IDE, everything is intentionally simplified: one file, one run button, one console, minimum settings. This is great for your first steps. But later, you'll need an environment that helps you not only write, but also read, fix, test, and not be afraid of changes.

What changes when moving to a local IDE

The main change is very simple: your code becomes your local project — a set of files in a folder on your computer, which the IDE treats as a single entity. This means you get proper project navigation, issue diagnostics before running, and convenient renaming.

To consolidate these feelings, it's useful to compare a Web IDE and a local IDE in a single table:

2. What is an IDE

IDE (Integrated Development Environment) is not just a buzzword. It's an entire suite of development tools: a smart code editor, compiler integration tools, a debugger, a hint system, and project management.

When you write code in a regular text editor (like Notepad or Vim), you have to manually run the build via the terminal, look for errors in the console, and sometimes remember which folder contains the required package. An IDE does all this for you — and a little bit more:

• integrates with the strict Go compiler, highlighting unused variables and imports even before running;
• automatically formats the code (Go has the gofmt standard for this, and the IDE runs it for you upon saving);
• allows you to instantly navigate to a specific function, even if it's in the language's standard library;
• lets you add external modules in a couple of clicks.

3. Overview of popular Go IDEs

The Go world historically has a strong culture of CLI tools. Therefore, the language is perfectly supported both in specialized, heavy-duty IDEs and in lightweight editors thanks to the Language Server Protocol (the gopls server, which "tells" the editor how your code works).

JetBrains GoLand

Unlike IntelliJ IDEA or PyCharm, GoLand does not have a completely free version (Community Edition). It is a professional proprietary product that requires a paid subscription for full commercial use.

However, there are ways to legally use GoLand for free:

• Free Trial: you can download the stable 2025.3 version from the official website and use the fully functional IDE for free for 30 days. This is perfectly sufficient to start learning.
• Early Access Program (EAP): before the official release of new versions, JetBrains publishes test builds. They are absolutely free and work from the moment each build is published.
• Special Licenses: students of verified educational institutions can get a full license for free for their entire study period.

Despite its paid status, we strongly recommend using GoLand for our course. It's an environment that has the best static analysis system for Go on the market, understands goroutines and interfaces out of the box, and saves dozens of hours searching for silly compilation errors.

VS Code

• It's more of a "super-editor" than a full-fledged IDE out of the box.
• All Go-related logic (autocomplete, go to definition, formatting) is provided by the official extension and the gopls server.
• Great for working on less powerful computers.
• Often requires an understanding of how paths and environment variables work in the terminal, so it might cause some difficulties at the start.

Alternatives to JetBrains and why it's okay

Sometimes students get anxious: "If I start with JetBrains, am I tied to it forever?". No. The goal of the course is not for you to learn a single Run button, but for you to understand the development process.

A strong point of the Go ecosystem is the good tooling around the language. Historically, Go developed formatting and analysis tools as part of the language culture (for example, gofmt became the norm very early on), and the idea that "tools should help" is no accident.

A JetBrains IDE is just one convenient way to "plug into" this culture. But generally, there are different paths: someone works in VS Code, someone in Vim/Emacs with LSP, someone likes minimalism. Within the course, we choose JetBrains as an intuitive and powerful "combine" that takes care of a lot of routine tasks.

4. For quick tests: Go Playground

Sometimes you only need to check a couple of lines of code — for instance, to remember how string formatting works in the fmt package, or to quickly test a mathematical formula. Launching a whole IDE or creating a new project for this can be overkill.

In such cases, go.dev/play is a lifesaver. This is the official online sandbox from the creators of the Go language.

• Pros: runs right in the browser, lets you instantly execute code, and easily share it using the Share button (very handy if you want to show your code to a mentor).
• Cons: it's not an IDE. There is no folder structure, you can't properly work with keyboard input (fmt.Scan will behave unpredictably), and there is no full autocomplete.

5. Advantages of a strict development environment

The Go language is famous for its simplicity, but at the start, the ecosystem of modules and file paths can confuse a beginner. We choose GoLand because this environment takes care of all the environment setup routine.

Early diagnostics

The Go compiler is one of the strictest in the industry. Unlike many other languages, if you declare a variable in Go but never use it, the program will simply refuse to compile. The same goes for importing libraries: imported "fmt" but didn't print anything to the screen? Compilation error.

GoLand makes this strictness comfortable. The environment analyzes your code continuously, right as you type. An unused variable or a type error is instantly underlined in red. You catch a typo immediately, with your eyes, before your brain starts inventing complex theories about why the project broke.

JetBrains Junie AI Agent

Modern versions of JetBrains IDEs feature Junie — not just a smart autocomplete, but a full-fledged AI agent that "sees" the context of your project. During the trial period, AI Assistant features are also available.

Junie can independently find the cause of an error, explain how an unfamiliar function from the Go standard library works, or suggest solution logic. This is a powerful tool, but for a beginner, it's a double-edged sword. Use it to ask it to explain a complex piece of code ("Junie, why does Scan block the execution of this line?"), but try to write solutions to problems yourself. The AI agent won't be with you at a job interview.

In the next lecture, we will download the Go compiler and install our local development environment.
