Things people build with this

USE CASE 1

Write new code features by describing them in plain English and letting the AI generate the implementation.

USE CASE 2

Debug production issues by asking the AI to trace through your codebase and identify root causes.

USE CASE 3

Refactor legacy code by having the AI suggest and apply improvements without switching tools.

USE CASE 4

Learn unfamiliar codebases by asking questions about how specific files or functions work.

In plain English

Roo Code is a VS Code extension that puts an AI coding assistant directly inside your editor. The idea is that instead of switching between your code editor and a separate chat interface, you can ask an AI for help, have it write or modify code, debug issues, and answer questions about your codebase, all from within Visual Studio Code. It works through several different modes tailored to different tasks: Code Mode handles everyday editing and file operations, Architect Mode helps you plan systems and write specifications, Ask Mode gives quick explanations and answers, and Debug Mode helps trace bugs and isolate root causes. You can also create custom modes tailored to your team's workflow. Roo Code connects to large language models via various providers and supports extending its capabilities through MCP (Model Context Protocol) servers, which let it interact with external tools and data sources. It can read your codebase, generate code from plain-English descriptions, refactor existing code, and write documentation. You would use Roo Code if you want a powerful AI pair programmer living inside VS Code, without switching to a separate tool. It is written in TypeScript and has over 3 million installs.
