Bracket Pair Colorizer#
The VS extension Bracket Pair Colorizer matches corresponding brackets in your code with the same color. This is a great help when you’re working with things like nested components, objects, or functions that all have brackets or parentheses.
With this simple extension, it’s much easier to find matching pairs and understand your code. The biggest advantage of this extension is improved navigation and accessibility. It also makes it easier for others to read and understand your code.
Better Comments#
Better Comments is an extension used for writing human-friendly comments in your code, which is helpful for you and anyone who is reading source code (especially for teams). Descriptive, human-friendly comments save so much time for everyone involved.
With this VS extension, you can use the following characters after a double forward slash // to add easier commenting:
*for highlighted text!for errors and warnings?for queries and questions//for strikethroughTODOfor to-dos
Snippets#
Snippets are an excellent add-on for productivity. Snippets is a collection of various extensions for the most commonly used programming languages. The React Snippet is a popular extension, for example, that allows you to use and create shorthands for things you do over and over again.
Some popular options are:
- Angular Snippets (version 11)
- Python
- JavaScript (ES6) code snippets
- HTML Snippets
- Vue 3 Snippets
AI Code Assistants and Autocomplete#
In 2025, one of the most talked-about categories in the VS Code extension marketplace is AI-powered code completion and assistant tools. These are often considered among the best VS Code extensions today.
-
GitHub Copilot: Suggests full lines or code blocks as you type, based on both your local context and the broader programming patterns. In many recent roundups it appears near the top.
-
Tabnine: A privacy-oriented AI completion tool that runs locally or with limited cloud support. It integrates deeply into VS Code and complements IntelliSense suggestions.
-
Codeium / Windsurf: A free alternative AI completion tool good for extending support across multiple languages.
These assistants help you complete boilerplate faster, generate test scaffolding, refactor, or even see suggestions with comments. Among the best VS Code extensions, AI tools now often compete first place over traditional formatting or linting tools.
CSS Peek#
CSS Peek is a great extension for web developers, as it allows you to “peek” at the styles for CSS classes, ids, and even HTML tags. This extension is similar to the Brackets feature called CSS Inline Editors.
CSS Peek supports symbol definition tracking for any CSS selector, for example:
- Peek: load a CSS file inline for quick edits (
Ctrl+Shift+F12) - Go To: jump directly to a CSS file (
F12) - Hover: show the definition when hovering over a symbol (
Ctrl+hover)
Prettier#
The Prettier extension is a formatter that helps to keep code style consistent. You can configure your settings however you need and save with shortcuts. Prettier is one of the most popular code formatters out there, with over 38.5k stars on GitHub.
Prettier will automatically fix formatting issues in your code, like fixing the mix of single and double-quotes or an irregular use of semicolons.
This extension works with the following technologies: JavaScript, TypeScript, Java, JSON, CSS, HTML, Vue, Angular, Markdown, YAML, and more.
Relative Path#
Relative Path is a great extension for writing import statements. You can easily get the relative path for any file using shortcuts in your workspace. Instead of searching for file’s location, you only need the file’s name, and the extension will provide the relative path from the current location to that target file.
Note: It will require some configuration if you’re working with a large mono-repository.
Icons#
Icons allows you to create descriptive icons to help differentiate between files and folders. This makes your code more visual, so it’s easier to work as teams, return to code after some time, or even just make the experience more fun. For example, you could change the color of a default folder icon using the command palette.
There are a few different Icons extensions, including
- vscode-icons
- Material Icon Theme
- Material Theme Icons
- Simple icons
Live Preview, Auto-Reload and Tag Tools#
To make web development smoother, these extensions are often cited among the best VS Code extensions:
-
Live Server: Launches a local development server that auto-refreshes your browser on file save. Ideal for HTML/CSS/JS work.
-
Auto Rename Tag: Automatically renames matching HTML/XML tags when you edit one side.
-
Path Intellisense: Suggests filenames and path completions as you type import paths or links.
These may feel lightweight, but they reduce friction and interruptions in your dev workflow.
GitLens#
The GitLens extension combines the capabilities of Git with VSCode that allows you to visualize code authorship via Git. GitLens is great for understanding code better, so you can learn who, why, and when code was changed. It also allows you to explore the history and evolution of a codebase.
It also has many other features to use such as:
- Revision navigation through file history
- A current line blame annotation at the end of the line showing the commit
- A status bar blame annotation for the commit and author who last modified the current line
Performance and Import Monitoring Tools#
Beyond features, modern extension lists include small but powerful performance helpers:
-
Import Cost (already listed): shows size of imported packages inline, so you see how “heavy” dependencies are.
-
File Size / Bundle Analyzer Extensions: show file sizes, chunk sizes, or even webpack bundle breakdowns.
-
Dependency graph / code metrics tools: in complex codebases, having visual metrics (line count, complexity) can guide refactors.
These utilities help you see behind the scenes and make choices about code health and dependency bloat.
Import Cost#
The Import Cost extension helps with productivity by showing the estimated size of an import package. This helps to avoid issues by tracking the size of added dependencies.
If an import is too large, the Import Cost extension will warn you so you can reconfigure based on the requirements you set.
Linting, Spell Checking and Static Analysis#
To maintain code quality, linting and static analysis extensions rank high in “best VS Code extensions” lists.
-
ESLint: Runs lint rules as you code, warns of syntax errors, coding style breaches, and potential bugs. It integrates with Prettier in many setups.
-
Code Spell Checker: Highlights typos in comments, strings, markdown—very useful in documentation-heavy projects.
-
Stylelint / CSSLint: For CSS / SCSS files, helps flag errors in style declarations or rule misuse.
-
MarkdownLint: Standardizes markdown formatting and warns about heading levels, line length, or blank lines.
These tools give you immediate feedback and help enforce team style consistency.
Markdown All in One#
Markdown All in One is a very useful extension for all things markdown related. It adds features like auto-preview, shortcuts, syntax autocomplete, and more. Markdown is commonly used across many tech fields, and this extension makes it even easier to work with, boosting productivity and speed.
With Markdown All in One, you can use shortcuts to alter text and add things like bold, italics, etc. It also has useful automations for working with things like lists and math. Here are some common commands:
- Create a Table of Contents
- Remove section numbers
- Toggle code block
- Print current document to HTML

IntelliSense#
IntelliSense is what VS Code calls its own code autocomplete feature, but it encompasses several different functionalities as well. It also includes parameter info, quick info, and member lists. Highlighted suggestions can be inserted with Tab or Enter.
When suggestions are accepted, Intellisense remembers what partial characters were typed. That way, if you type those characters again the accepted suggestion will appear first. This effectively allows you to customize recommendations by being deliberate with when you accept them. For example, if you type co and then accept the autocomplete: console, the next time you type co, console will be suggested first. If you type con and select const, then that choice will be remembered also.
IntelliSense comes out of the box set up for JavaScript, TypeScript, JSON, HTML, CSS, and SCSS, and Less. But, it can easily be installed for almost any language of your choice with the language package extension. There are language extensions that encompass advanced IntelliSense features for:
- Python
- C/C++
- C#
- Java
- Go
- Dart
- PHP
- Ruby
Personalization: Intellisense can also be customized with keybindings!
Choosing, Pruning and Security of Extensions#
It’s easy to let your VS Code become extension-heavy, but it’s smart to manage them well. Among the best VS Code extensions is the practice of managing them.
-
Only install extensions that give clear value; disable ones you use rarely
-
Monitor startup / memory overhead of active extensions
-
Review permissions / network calls of extensions—some may access the internet or run background tasks
-
Keep extensions updated and audit any new extension you add
As a caution, the VS Code extension ecosystem has had instances of malicious extensions appearing in marketplaces—so vet new extensions, check reviews and author credibility before installing.
VS Code accessibility issues#
With any code editor or IDE, setup can be a pain. VS Code is fairly simple when it comes to setting up extensions, but it can be a little trickier to find all of the accessibility accommodations at first.
Luckily, VS Code has plenty of modularity when it comes to accessibility. The official documentation covers a wealth of accessibility settings, especially those related to visibility. There are options and keyboard shortcuts to help with things like zoom, custom color contrast settings, and even navigation.
VS Code offers support for multiple different screen readers too. They have tested and confirmed the use of NVDA and JAWS on Windows, VoiceOVer on macOS, and Orca on Linux. When VS Code detects a screen reader, it defaults to a screen reader optimized mode that alters the UI for the editor and Integrated Terminal.
There are multiple different functional sections of the code editor that can be adjusted for accessibility. The terminal, status bar, and debugger are all modifiable. Additionally, changes can be made to the hover function for use with screen magnifiers, and audio cues can be added for use with screen readers.
There are even a few extensions that you can add to VS Code that help you keep accessibility in mind while you code. The first is called Webhint, and although it does more than just flag accessibility issues, we all could use some accessibility-related reminders every now and then. It can analyze HTML, CSS, JavaScript, TypeScript, JSX, and more all while you code. The issues highlighted by Webhint appear in the error pane. Pairing Webhint with the extension Error Lens allows accessibility issues (along with regularly flagged errors) to be even more visible. Error Lens takes problems normally displayed in the error pane and displays them on the line where they occur.
When the two extensions are combined VS Code can remind you to add alt text to images, suggest that elements need more color contrast, and much more, all in the line that the reminder is relevant to. Webhint and Error Lens are especially useful for accessibility compliance for front-end devs, but really any developer can get use out of them.
