Codeium offers a compelling free alternative to Copilot with strong performance in both local and cloud development environments. Its ability to generate intelligent suggestions directly from natural language comments makes it particularly valuable for developers who prefer to sketch functionality in plain English before implementing.
Cline
Key Features:
- Unique “plan-then-act” approach to code generation
- Explores possible implementation strategies before writing code
- Transparent token usage and cost tracking
- Educational approach that helps developers improve
Why It Stands Out:
Unlike other AI assistants that immediately generate code, Cline’s thoughtful approach walks you through potential implementation strategies first. This deliberate process helps developers make more informed architectural decisions and better understand the reasoning behind suggested solutions.
How to Choose the Right Extensions for Your Workflow
With over 30,000 extensions available, selection paralysis is real. Consider these factors when building your perfect VS Code environment:
- Project Requirements: Choose extensions that directly address the specific technologies and frameworks used in your projects.

Which VS Code extensions are best for web development?
For web development, essential extensions include Live Server for real-time previews, ESLint and Prettier for code quality, GitLens for version control, and language-specific tools like JavaScript (ES6) Code Snippets, CSS Peek, and HTML CSS Support. REST Client is also highly recommended for testing APIs directly within VS Code.
Are there any VS Code extensions for improving code security?
Yes, several VS Code extensions focus on security in 2025. Extensions like KICS help identify security vulnerabilities in infrastructure as code, while LambdaTest assists with cross-browser testing to ensure application security across different environments. Jit is another security-focused extension that integrates security tools directly into your development workflow.
How can I manage multiple VS Code extension configurations?
VS Code’s Settings Sync feature (built-in since 2020) allows you to synchronize extensions, settings, and themes across multiple devices. For project-specific extension requirements, you can use the “.vscode/extensions.json” file to recommend extensions to team members, ensuring consistent development environments across your team.
Do VS Code extensions affect performance?
Yes, each extension consumes system resources and can impact VS Code’s startup time and overall performance. Extensions with language servers or heavy background processing (like some AI assistants or advanced linters) tend to have the largest impact. You can use VS Code’s built-in “Developer: Startup Performance” command to identify extensions that significantly impact load times.
