Roo Code
Decision note
Roo Code is a VS Code extension and agent framework forked from Cline, with enhanced autonomous coding capabilities and additional agent modes. Roo is open source (Roo / community-maintained), free to use, and operates with the same bring-your-own-key model as Cline. Best paired with frontier Claude or DeepSeek models for autonomous workflows.

Best LLMs for this agent
Most Roo Code users run Claude Sonnet 4.6 for autonomous coding because it is the default high-accuracy Claude pairing for this Cline-family workflow.
Claude Opus 4.6 is the stronger Claude option for longer autonomous edits and difficult reasoning-heavy tasks.
DeepSeek V4 Pro is the strong open-weights alternative when cost matters but Roo still needs capable autonomous coding behavior.
