16 best VS Code extensions for developers (2026)

The useful part

The right combination depends on your stack and workflow, but the most useful extensions generally improve coding speed, debugging, testing, version control, remote development, and deployment. It already includes a terminal, Git tools, debugging, and basic support for several programming languages. Extensions add more specialized tools when your project or workflow needs them.

How it works

• Agent mode handles work with several connected steps, such as changing multiple files, running tests, and responding to failures.
• code can contain incorrect logic or weak security checks, so run your tests and take extra care with authentication, permissions, payments, and other code that handles sensitive data.
• Paid individual plans start with Copilot Pro at $10 per user/month, which includes unlimited code completions and 1,500 monthly AI Credits.
• It can inspect your project, edit files, run terminal commands, and keep working through a task as it finds new information.
• Cline can search for the relevant code, update the affected files, run the tests, and use any failures to work out what still needs fixing.

What to take from it

Because it can make changes and run commands on your computer, Cline keeps you involved by default. VS Code normally underlines a line and puts the full explanation in the Problems panel. That means you can keep VS Code focused instead of loading it with tools you won't use.

Example or evidence

• Python tools belong in Python projects, while Tailwind CSS IntelliSense only helps in projects that use Tailwind CSS.
• VS Code, command-line checks, and automated builds will then apply the same formatting rules.
• Add Hostinger as a preferred source on Google The best VS Code extensions for developers include GitHub Copilot for AI-assisted coding, Prettier for formatting, ESLint for code quality, GitLens for Git...
• Some extensions are project-specific, so only install them where they're useful.
