Best AI Plugins for VS Code (2025) | Generated by AI
As of March 20, 2025, determining the “best” AI plugin for Visual Studio Code (VS Code) depends on your specific needs, such as code completion, debugging, test generation, or chat-based assistance. Based on the latest trends and available information, here are some of the top AI-powered VS Code extensions widely regarded for their capabilities, along with their key features:
- GitHub Copilot
- Why It’s Great: Developed by GitHub in collaboration with OpenAI, GitHub Copilot is often considered the gold standard for AI-assisted coding. It acts as an “AI pair programmer,” offering real-time code suggestions, autocompletion, and even generating entire functions based on comments or context.
- Key Features:
- Inline coding suggestions as you type.
- Supports a wide range of languages (e.g., Python, JavaScript, TypeScript, C#, etc.).
- Chat functionality (via GitHub Copilot Chat) for conversational assistance.
- Pros: Highly accurate, integrates seamlessly with VS Code, and excels with popular languages and frameworks.
- Cons: Requires a subscription ($10/month after a trial), which might not suit everyone.
- Best For: Developers wanting a robust, all-in-one AI coding companion.
- Codeium
- Why It’s Great: Codeium is a free alternative to GitHub Copilot, offering similar AI-powered code completion and chat features. It’s gained popularity for its accessibility and performance.
- Key Features:
- Autocompletion for over 70 programming languages.
- Chat interface for code generation and explanations.
- Works across multiple IDEs, including VS Code.
- Pros: Free for individual use, lightweight, and versatile.
- Cons: May not match Copilot’s depth of training or team collaboration features.
- Best For: Budget-conscious developers or those exploring free AI tools.
- Tabnine
- Why It’s Great: Tabnine uses machine learning to provide context-aware code completions, learning from your codebase and coding patterns over time.
- Key Features:
- Supports 80+ languages and frameworks.
- Offers AI chat for code-related queries.
- Customizable for team-specific workflows.
- Pros: Strong focus on privacy (can run locally), adapts to your style, and has a free tier.
- Cons: Advanced features require a paid plan, and it may be less intuitive for beginners.
- Best For: Teams or individuals needing privacy-focused, customizable AI assistance.
- Visual Studio IntelliCode
- Why It’s Great: Developed by Microsoft, IntelliCode enhances VS Code’s built-in IntelliSense with AI-driven suggestions, prioritizing completions based on your code context.
- Key Features:
- Context-aware code completions ranked by relevance.
- Trained on thousands of open-source GitHub repositories.
- Supports languages like Python, TypeScript/JavaScript, and Java.
- Pros: Free, lightweight, and tightly integrated with VS Code.
- Cons: Less feature-rich compared to Copilot or Codeium (e.g., no chat functionality).
- Best For: Developers who want a simple, no-cost AI boost to IntelliSense.
- Cline (formerly Continue)
- Why It’s Great: Cline is an emerging favorite for its unique “plan-then-act” approach, allowing you to strategize with the AI before it generates code. It’s highly customizable and supports multiple LLMs.
- Key Features:
- Plan mode to outline coding steps, followed by act mode to implement.
- Integrates with models like GPT-4, Gemini, or local LLMs via Ollama.
- Tracks token usage and costs for transparency.
- Pros: Free and open-source, great for deliberate coding workflows.
- Cons: Requires more setup (e.g., API keys or local models), less plug-and-play than Copilot.
- Best For: Developers who prefer control and transparency in AI interactions.
Recommendation
- If you want the most powerful, seamless experience and don’t mind paying: Go with GitHub Copilot. It’s the most polished and widely adopted option.
- If you need a free, capable alternative: Codeium is an excellent choice for its balance of features and cost.
- If you prioritize customization or local execution: Cline or Tabnine might suit you best.
Ultimately, the “best” plugin depends on your workflow. For general coding productivity, GitHub Copilot and Codeium are the most frequently praised in 2025. I’d suggest trying a couple (starting with Codeium since it’s free) to see which aligns with your needs!
