Ralphy is an autonomous AI coding loop tool that orchestrates multiple AI coding assistants to work through tasks until completion. It supports a range of AI engines including Claude Code, GitHub Copilot, Gemini CLI, OpenCode, Cursor, Codex, Qwen-Code, and Factory Droid, allowing users to switch between them via CLI flags. The tool runs in two modes: single-task for quick commands like adding a feature, or PRD mode where it works through a task list defined in a markdown file. It includes project configuration options for storing rules, boundaries, and commands that the AI agents must follow.
