Roo Code — Your AI-Powered Dev Team in VS Code
Roo Code (formerly Roo Cline) is a free, open-source VS Code extension that turns large-language-model agents into full-stack collaborators. Using the Model Context Protocol (MCP), it can read and refactor entire code-bases, run tests and terminal commands, launch headless browsers for end-to-end checks, and integrate with any frontier or local model—from GPT-4o and Claude to Grok or Ollama.
Developers switch between specialised modes—Code, Architect, Debug, Ask, or custom YAML personas—while Roo maintains deep context with embeddings and diff-based edits. Permission-gated writes keep you in control, making Roo Code suitable for hobby projects and enterprise workflows.
With 500 k+ VS Marketplace installs, 15 k+ GitHub stars and weekly releases, Roo Code has emerged as a leading open alternative to proprietary tools such as Copilot, Cursor and Windsurf.
