The Cline fork that took off

Roo Code is a community-driven, open-source AI coding agent for VS Code (a fork of Cline) that plans, edits, and runs commands across your workspace. It supports every major model provider - OpenAI, Anthropic, Google, Ollama, and more - so you are never locked to one vendor. Its Boomerang subtask system and custom modes make it a serious autonomous-coding option that is 100% free if you bring your own key.

Who it's for: Developers who want Cursor-class agentic coding without a subscription and with total model freedom.
