What Roo Code is

Roo Code is an open-source AI coding agent for VS Code. It started as a community fork with a focus on autonomous, multi-step coding tasks inside the editor.

Key features

  • VS Code native - lives inside your editor.
  • Autonomous mode - can plan and execute multi-file changes.
  • Model flexibility - bring your own API keys or local models.
  • Task-focused - designed for concrete coding tasks, not just chat.
  • Active community - popular among VS Code users who want a free alternative to Cursor.

Install

Install from the VS Code Marketplace.

Use case

Roo Code is ideal if you live in VS Code and want an open-source agent that can make real edits without leaving the editor. It is a direct alternative to Cursor’s agent features.

Honest caveat

The Roo Code team has also launched Roomote, a source-available cloud/self-hosted teammate. Roo Code itself remains the VS Code extension. Make sure you are comparing the right product for your workflow.
