Open Ralph Wiggum provides a persistent CLI loop for AI coding agents, enabling them to work iteratively on tasks without manual restart. Users run a prompt and the agent loops autonomously. It supports multiple backends including Claude Code, OpenAI Codex, Copilot CLI, Cursor Agent, Qwen Code, and OpenCode, selectable via the –agent flag. It also offers sandboxing integration to isolate each task in a safe Linux environment.
