Overview of VSCode AI Extensions and Tools

Visual Studio Code (VSCode) is a free, open‑source code editor developed by Microsoft, released in 2015 and available on Windows, macOS, and Linux. It offers a large extension marketplace that lets users add language support, formatting tools, version‑control integration, themes, and more.

With AI increasingly integrated into programming, VSCode’s ecosystem now includes many AI‑assisted extensions that boost developer productivity.

1. Cline – A powerful VSCode plugin that integrates multiple AI models (OpenAI, DeepSeek, Claude 3.5, etc.) for code generation, terminal commands, web‑development assistance, and headless‑browser debugging. Extension link: Cline Marketplace . GitHub: github.com/cline/cline .

2. Roo Code – Formerly Roo Cline, this AI programming assistant builds on Cline with support for DeepSeek‑V3, DeepSeek‑R1, OpenAI, Google Gemini, custom APIs, and local models like Ollama. Extension link: Roo Code Marketplace .

3. Continue – An open‑source AI code assistant that connects to large language models (OpenAI, DeepSeek, Claude, etc.) to provide code completion, generation, optimization, and error fixing via a chat interface. Extension link: Continue Marketplace . GitHub: github.com/continuedev/continue .

4. Other notable extensions :

Codeium – Free AI‑driven code completion supporting 70+ languages.

通义灵码 (Tongyi Lingma) – Alibaba’s AI coding tool for multiple languages and IDEs.

Fitten Code – AI assistant from Fitten Tech based on a proprietary large code model.
