Open source VS Code extension with basic features. Apache 2.0 license.
Roo Code (formerly Roo Cline) is an open-source, multi-agent VS Code extension that gives every developer a full AI dev team inside the editor. Fork of Cline with expanded capabilities: multiple specialized agent modes (Code, Architect, Ask, Debug), boomerang orchestration to delegate sub-tasks, MCP support, and support for all major LLM providers. 38K+ GitHub stars as of May 2026.
+ Pros
- Multi-agent modes (Code, Architect, Ask, Debug) with specialized prompts and tools for each role
- Boomerang orchestration enables complex multi-step workflows across parallel sub-agents
- Works inside VS Code, Cursor, Windsurf — no editor lock-in
- Fully open source Apache 2.0 — 38K+ stars and very active maintenance
- MCP-native and BYO LLM — complete flexibility on tooling and model provider
− Cons
- Requires LLM API key — no free inference included
- Setup complexity higher than commercial tools like Cursor or GitHub Copilot
- Roo Cloud not yet available — cloud execution still requires local setup
- Multi-agent boomerang workflows can accumulate significant token costs with expensive models

Roo Code (originally Roo Cline) is a VS Code extension and fork of Cline that expanded the single-agent model into a full multi-agent dev team inside the editor. Launched in late 2024 and growing to 38K+ GitHub stars by May 2026, it is one of the most actively maintained open-source coding agent projects. The core innovation is agent modes: Code (writes and edits), Architect (designs systems), Ask (answers questions without editing), and Debug (diagnoses issues) — each with its own system prompt, tool access, and context strategy.
Boomerang orchestration lets the active agent spawn and delegate sub-tasks to other agents, each in an isolated context window, and collect the results — enabling complex multi-step workflows without overflowing a single context. Roo Code is provider-agnostic (Claude, GPT, Gemini, local models via Ollama) and MCP-native, allowing it to connect to any external tool server. The extension works inside VS Code, Cursor, Windsurf, and any VS Code fork, and the team is developing Roo Cloud for hosted execution.

Signature Snippet
Open Roo Code in VS Code and switch to Architect mode. Type: 'Design the database schema and API layer for a multi-tenant SaaS billing system.' Architect mode produces a full design doc. Then Roo Code's boomerang orchestration hands off implementation sub-tasks to Code mode agents in parallel — one for the schema migration, one for the API routes, one for the tests — each running in its own context window.More in this Space
