An open-source AI coding agent for VS Code with switchable modes for architecting, coding, debugging, and asking questions.
Roo Code is an open-source AI coding agent for VS Code, built as a fork of Cline with its own ideas. Its signature feature is modes: switch between Architect for planning, Code for building, Debug for fixing problems, and Ask for questions, and the agent behaves differently in each mode. You can also create custom modes for your own workflow.

- Edits files, runs commands, and browses the web
- Use different models for different modes
- Works with Claude, GPT, Gemini, and local models

How it works
Roo Code can edit files, run terminal commands, and browse the web, and it keeps the conversation and the plan visible so you can follow what it is doing. It supports many models through your own API keys, and it can use different models for different modes, so you can pair a strong model for planning with a cheaper one for routine edits.
The extension is free and open source; you pay only for the model API usage you choose. That makes Roo Code a flexible, low-cost agent for developers who like to tune their setup, and a good learning tool for students exploring AI-assisted development.
