If you’re a developer, chances are Visual Studio Code (VS Code) is already your editor of choice. It’s fast, lightweight, free, and works beautifully across platforms. But what truly makes VS Code special isn’t just the editor itself — it’s the massive ecosystem of VS Code extensions.
The right extensions can transform VS Code from a simple editor into a powerful, personalized development environment. They help you write cleaner code, avoid bugs, work faster, and stay focused.
In this article, I’ll share 15 must-use VS Code extensions that consistently improve developer productivity, whether you’re a beginner or an experienced professional. I’ll explain what each extension does, why it’s useful, and who should use it — in clear, simple language.
Let’s get started 🚀
1. Prettier – Code Formatter
Prettier is one of the most popular Visual Studio Code extensions, and for good reason.
It automatically formats your code every time you save a file. Indentation, spacing, quotes, line breaks — Prettier takes care of everything.
Why developers love Prettier:
- Keeps code style consistent across projects
- Saves time during code reviews
- Eliminates formatting debates in teams
Best for: JavaScript, TypeScript, HTML, CSS, JSON, React, Vue, and more.
Once you use Prettier, manually formatting code feels unnecessary.
2. ESLint
ESLint is a must-have extension for writing clean and reliable JavaScript or TypeScript code.
It analyzes your code as you type and warns you about:
- Syntax errors
- Unused variables
- Potential bugs
- Bad coding practices
Why ESLint matters:
- Catches mistakes early
- Encourages best practices
- Improves long-term code quality
For any serious JavaScript developer, ESLint is non-negotiable.
3. GitLens — Git Supercharged
GitLens turns Git into a powerful visual experience inside VS Code.
It shows you:
- Who wrote each line of code
- When it was changed
- Why it was changed (commit messages)
Why GitLens boosts productivity:
- Makes debugging easier
- Helps understand old or unfamiliar code
- Great for team collaboration
If you’ve ever wondered, “Why does this code exist?”, GitLens usually has the answer.
4. Live Server
Live Server is one of the most beginner-friendly VS Code extensions.
It launches a local development server and automatically refreshes your browser whenever you save a file.
Why it’s so useful:
- Instant visual feedback
- No manual browser refresh
- Perfect for frontend development
Best for: HTML, CSS, JavaScript beginners and frontend developers.
5. Bracket Pair Colorizer (or Built-in Alternative)
Nested brackets can quickly become confusing, especially in complex logic.
This extension colors matching brackets differently, making code easier to read and understand.
Why developers appreciate it:
- Improves readability
- Reduces logical mistakes
- Makes debugging simpler
VS Code now includes similar functionality by default, but this extension popularized the feature.
6. Auto Rename Tag
Auto Rename Tag is a small extension that makes a big difference.
When you rename an opening HTML or JSX tag, the closing tag updates automatically.
Why it’s a must-have:
- Prevents broken markup
- Saves time
- Eliminates annoying mistakes
If you work with HTML, React, or Vue, this extension feels like magic.
7. Path Intellisense
Path Intellisense auto-completes file paths while you type import statements.
Instead of guessing folder names, you get accurate suggestions instantly.
Why it improves workflow:
- Faster imports
- Fewer path errors
- Cleaner code
This is one of those developer productivity tools you don’t notice — until it’s gone.
8. Material Icon Theme
Material Icon Theme enhances the VS Code file explorer with clean, meaningful icons.
Each file type gets its own recognizable icon.
Why it’s popular:
- Better visual clarity
- Faster navigation
- Cleaner project structure
It doesn’t change your code, but it definitely improves your daily experience.
9. Code Spell Checker
Typos in variable names, comments, and strings happen more often than we admit.
Code Spell Checker highlights spelling mistakes without interrupting your workflow.
Why it matters:
- Improves code readability
- Helps non-native English speakers
- Makes projects look more professional
Especially useful for comments, documentation, and user-facing text.
10. REST Client
REST Client allows you to send HTTP requests directly from VS Code.
You can create .http files and test APIs without opening external tools.
Why backend developers love it:
- Fast API testing
- Version-controlled requests
- Everything stays inside the editor
It’s a great alternative if you prefer a lightweight API testing setup.
11. Docker
If you work with containers, the Docker extension is essential.
It lets you:
- Manage containers and images
- View logs
- Build and run Docker files
Why it’s powerful:
- Better visibility into containers
- Faster DevOps workflows
- Seamless VS Code integration
Perfect for backend developers and DevOps engineers.
12. Thunder Client
Thunder Client is a lightweight API testing tool built directly into VS Code.
Think of it as a simpler, faster alternative to Postman.
Why developers choose Thunder Client:
- Clean interface
- Minimal setup
- No external applications needed
It’s ideal if you want to test APIs without leaving your editor.
13. IntelliCode
IntelliCode uses AI to provide smarter code completions based on real-world patterns.
Instead of generic suggestions, it predicts what you’re most likely to write next.
Why IntelliCode stands out:
- Faster coding
- Better suggestions
- Adapts to your style
It feels subtle, but over time it significantly improves coding speed.
14. Better Comments
Better Comments helps you organize and highlight comments visually.
You can categorize comments as:
- TODOs
- Warnings
- Questions
- Notes
Why it’s useful:
- Cleaner documentation
- Easier navigation
- Better collaboration
Readable comments make long-term projects easier to maintain.
15. Todo Tree
Todo Tree scans your entire project and lists all TODO and FIXME comments in one place.
No more searching through files manually.
Why it’s a productivity booster:
- Keeps tasks visible
- Helps with planning
