1 What VS Code actually is
VS Code is a code editor that sits between lightweight text editors (Sublime Text, Notepad++, Vim) and full IDEs (IntelliJ IDEA, Visual Studio, Xcode). It starts quickly like a text editor, then becomes closer to an IDE as you add extensions for your language and workflow.
The product is built on Code - OSS, an open-source project under the MIT license. Microsoft distributes its own official builds on top of that base, adding branding, telemetry, and some integration features. The distinction matters if you care about licensing: the code is open, the binary you download from Microsoft is theirs.
Microsoft ships updates roughly monthly, and the extension ecosystem is one of the largest for any editor. That combination — fast start, free, extensible, cross-platform — is the reason it is the default choice for most web developers and a great many others.
A note on figures in this review
Extension counts, startup times, and feature parity claims change frequently. This review avoids quoting hard numbers where they cannot be verified in a stable way. Where a specific claim matters (for example, RAM use or licensing), we say what it is based on. For anything that affects your decision, verify on code.visualstudio.com and the extension marketplace before committing.
2 Features that actually matter
The product page lists dozens of features. In daily use, most of the value comes from five of them.
Fast startup
Compared with full IDEs, VS Code starts quickly on typical hardware. Startup time depends heavily on installed extensions — a fresh install is fast, a heavily configured one is slower. If you have heard conflicting reports, that is usually why.
IntelliSense
Language-aware autocomplete, parameter hints, and inline documentation, powered by language servers. Quality depends entirely on the language extension you install. TypeScript and Python are excellent; others vary.
Built-in Git
Stage, commit, branch, view diffs, and resolve simple merge conflicts without leaving the editor. For complex Git operations, you will still want the terminal — but for everyday work, the sidebar is faster than the CLI.
Integrated terminal
A real terminal panel inside the editor, on any platform. Split panes mean you can run a dev server, a test runner, and a shell side by side with your code. This alone is worth the migration for many developers.
Remote development
Work on a remote server, inside a Docker container, or in WSL as if it were local. The extension marketplaces support this officially. It turns VS Code into a client for almost any environment.
Optional AI (Copilot)
GitHub Copilot adds AI completions and chat. It is a separate paid product and not required. Useful if you write a lot of boilerplate; less valuable if your code is already short and specific.
3 Extensions that carry their weight
The extension marketplace is enormous, which is both the point and the problem — it is easy to install far more than you need. These are the ones that justify their resource cost for typical web and scripting work.
Prettier
Opinionated code formatter. Saves the argument about indentation and makes diffs cleaner. Works across JavaScript, TypeScript, CSS, JSON, Markdown, and more.
ESLint
Static analysis for JavaScript and TypeScript. Catches common bugs before runtime and enforces project conventions. Essential if the project already uses it.
Live Server
Runs a local development server with hot reload. Useful for plain HTML/CSS work; frameworks already ship their own dev servers.
GitLens
Shows inline blame, commit history, and file history without leaving the editor. Useful for understanding unfamiliar codebases. The free tier is fully usable.
REST Client
Sends HTTP requests from `.http` files and displays responses inline. Covers most API testing needs without opening Postman.
Language extensions
Install only the language extensions for stacks you actually work in. Each language server uses memory; installing five "just in case" is a common way to make VS Code feel slow.
4 Pros and cons
What works
- Genuinely free. No paid editor tier, no advertising inside the app, no watermarks.
- Fast to start. On a fresh install, noticeably lighter than a full IDE.
- Very large extension ecosystem. Almost any language or workflow has a maintained extension.
- Strong built-in Git. Handles most day-to-day version control without leaving the editor.
- Consistent across platforms. Windows, macOS, and Linux feel the same, and settings sync between them.
- Regular updates. The project ships changes on a monthly cadence, so rough edges get addressed.
Where it falls short
- Not an IDE out of the box. For Java, C#, Kotlin, or C++, a dedicated IDE provides deeper refactoring and code analysis than the equivalent extension set.
- Extension overload is real. Each additional language server or linter costs memory and startup time. Beyond about a dozen, the experience degrades.
- Copilot costs extra. The AI features most talked about require a separate subscription; without it, VS Code has no built-in AI.
- Settings are sprawling. The settings UI has grown complex and it is easy to lose track of what you changed and why.
- Electron base. Being built on Electron means a heavier memory footprint than a native editor. This rarely matters on modern machines but does on low-spec hardware.
- Telemetry default. Microsoft builds collect telemetry by default. It can be disabled in settings, but many users do not, and that is worth knowing.
5 Who it actually suits
The honest answer depends on what language ecosystem you work in. VS Code is the strongest general-purpose option for most developers, and less strong for languages where dedicated IDEs have more depth.
Reasonable if you
- Work primarily in JavaScript, TypeScript, Python, Go, Rust, or PHP
- Do web development, scripting, or mixed-stack work
- Want a fast editor that does not force a language on you
- Work across multiple machines and want settings to follow you
- Are learning to code and want something you will not outgrow quickly
- Need remote development over SSH, in containers, or through WSL
Probably not for you if you
- Work primarily in Java, Kotlin, or Android — IntelliJ IDEA is meaningfully better
- Work primarily in C# or .NET — Visual Studio or Rider are stronger
- Work primarily in Swift or Objective-C — Xcode is the standard tool
- Need deep framework-specific tooling that ships with a dedicated IDE
- Are on extremely limited hardware where even Electron overhead matters
- Prefer a terminal-only workflow — Neovim or Helix will be lighter and faster
The honest framing
VS Code is not the best tool for every language. It is the best default for most developers, and the differences between it and a dedicated IDE become smaller each year as extensions improve. But "most popular" is not the same as "right for your stack". If your language has a strong first-party IDE, try that first and use VS Code for everything else.
6 Alternatives worth knowing
These are the tools most often compared with VS Code. The comparison below is directional, not a set of ratings — SkillsInsider has not published in-depth reviews of IntelliJ, Sublime Text, Cursor, or Neovim, and this table does not claim to score them. Verify pricing, licensing, and current features on each vendor's own site.
| Tool | Licensing model | Where it is stronger than VS Code | Where it is weaker |
|---|---|---|---|
| VS Code | Free (Code - OSS is MIT) | General-purpose, web, cross-platform, extension breadth | Deep language-specific tooling for Java, C#, Kotlin |
| IntelliJ IDEA | Free Community tier; paid Ultimate | Deep Java, Kotlin, and Android tooling | Heavier on resources; slower to start |
| Sublime Text | Paid license, free evaluation | Very fast native editor; minimal memory use | Smaller extension ecosystem; less built-in tooling |
| Cursor | Free tier; paid Pro | AI-first editing experience | Depends on paid AI tiers for its main advantage |
| Neovim | Free and open source | Terminal-native; extremely light; modal efficiency | High setup cost; steep learning curve |
A practical approach: try VS Code first because it is free and does not commit you to anything. If you later find yourself fighting the editor for language-specific features, that is the signal to try a dedicated IDE for that stack. Many developers end up using VS Code for some work and a second editor for the rest.
7 Questions
Is VS Code really free?
Yes, for practical purposes. The editor is built on Code - OSS, an open-source project under the MIT license. Microsoft's official builds add proprietary branding and some telemetry, but there is no paid tier, no ads, and no feature locked behind a subscription for the editor itself. GitHub Copilot, the AI assistant, is a separate paid product.
VS Code vs IntelliJ IDEA — which should I choose?
They are built for different jobs. VS Code is a general-purpose editor that becomes an IDE through extensions; it is faster to start and lighter. IntelliJ IDEA is a dedicated Java and Kotlin IDE with deep language-specific refactoring, code analysis, and framework support that is difficult to replicate through extensions. Many developers use both rather than choosing. Verify current pricing and tier details on JetBrains' own site before deciding.
Does VS Code run well on low-end laptops?
Usually yes. VS Code runs on modest hardware, and its Electron base is well-optimised. The variable is extensions — a handful of lightweight extensions will not slow it down, but dozens of heavy ones, especially language servers for multiple stacks, will. On 4 GB of RAM, keep the extension list small and stick to one or two language stacks.
Is VS Code good for beginners?
Generally yes. The interface is approachable, there is a large amount of learning material, and you can start with basic HTML and CSS before adding extensions for other languages. The main beginner pitfall is installing too many extensions too early, which makes the editor feel overwhelming. Start minimal and add extensions as you learn what you actually need.
Do I need GitHub Copilot to use VS Code?
No. VS Code is fully functional without any AI features, and its core IntelliSense and debugging work without Copilot. Copilot is a separate paid subscription that adds AI-generated completions and chat. Whether it is worth the cost depends on how much repetitive code you write and whether your team already standardises on it.
Is this review sponsored by Microsoft?
No. SkillsInsider was not paid by Microsoft to publish this review. The link to code.visualstudio.com on this page is a plain, unmonetised link. We do not run an affiliate programme with Microsoft and receive no compensation for recommending VS Code.
If you want to try it
Download the official build from Microsoft. Start with a fresh install and the extensions for the language you already use. Add more only when you find yourself wishing the editor could do something specific.
