What Are the Best VSCode Extensions (Full Review)
The best Visual Studio Code extensions include Prettier, Live Server, Remote – SSH, Docker, and Copilot. Each of these extensions has unique strengths that make it the most useful for modern developers.
For example, Prettier automatically formats your code to help you save approximately two to three hours per week. Live Server refreshes your browser instantly for frontend tasks to save around one to two hours per week. Remote – SSH makes it easy for you to connect to and edit code on remote machines directly inside VSCode. Docker lets you manage containers, volumes, and images from VSCode itself. Copilot is the AI pair programmer that saves you nearly three to five hours a week with its code suggestions and completions. Let’s now look at these extensions in detail so you can choose the one you need.
1. Prettier
With over 40 million installations, Prettier is one of the best VSCode extensions to improve code readability. This opinionated extension for code formatting and style enforcer eliminates code style debates by formatting your code automatically on save.

- There are custom configuration options, such as changing the port number or root folder settings.
- It allows you to preview changes easily across various screen sizes for responsive design testing.
3. Remote – SSH
Remote – SSH VSCode extension is the best for those who work remotely or access remote servers. This extension allows you to connect to and develop on a remote machine using a local terminal. It runs different commands and extensions directly on your remote machine without a source code for easy remote development and debugging. Additionally, here are other features of Remote – SSH.
Key features
- It allows quick switching between environments.
- Easy machine access from multiple locations.
4. Docker
Docker finds a place among the top 10 VSCode extensions for those who use Docker containers. This extension makes building, managing, and deploying containerized apps from Visual Studio Code easier with the following features.

- It lets you easily view, manage, and interact with containers, registries, and images.
- Docker allows you to start, stop, and inspect containers or get a shell inside with one click.
- You can generate an optimized Docker file and .dockerignore files automatically using the “Add Docker files to Workspace” command.
- It allows in-container debugging by setting breakpoints in the code and launching a debugging session in the running container itself.
5. Copilot
GitHub Copilot is an AI pair programming copilot that offers intelligent suggestions for code blocks or entire code lines. Integrated with OpenAI, it opens a vast open-source code repository for practical and contextually aware suggestions to improve coding speed and serve as a valuable learning tool to help you learn various coding patterns.
Moreover, it collaborates actively with developers working across complex workflows and offers the following features.
Key features
- It creates API documentation, function summaries, and docstrings with semantic understanding.
- You can use natural language prompts in plain English to debug, refactor, and generate entire modules.

Frequently Asked Questions
Q1. Why do I need VSCode extensions?
While VSCode is an excellent, lightweight, and powerful IDE on its own, extensions help boost speed and efficiency, improve code quality, enhance readability, improve version control, and allow workspace customization by automating repetitive tasks, intelligent debugging, and supporting various programming languages.
Q2. Do extensions slow down VSCode?
VSCode extensions function in the background and can slow down VSCode if you have multiple extensions installed or if they have a functionality overlap. Moreover, poorly designed extensions can block the extension host or run unnecessary background tasks, causing slowdowns. Hence, periodically review your extensions and remove the ones you do not use. If there are any issues, you can identify and disable the problematic extension using the “Start Extension Bisect” feature.
Q3. Is it safe to use extensions on VSCode?
Well-maintained extensions from reputable publishers, like the ones mentioned in this article, are safe to use. Always review extension documentation and permissions, and do not install random extensions to ensure the safety of your workspace and editor APIs.
Q4. How often should I update VSCode extensions or remove them?
Review your extensions at least every 3 months to ensure you have the necessary performance improvements and security fixes, and to remove unused extensions to keep the editor fast.
