OpenClaw AWD Arena is a comprehensive platform for conducting Attack-With-Defense (AWD) cybersecurity competitions, specifically designed for training and evaluating large language models (LLMs) in offensive and defensive security scenarios. The system orchestrates isolated Docker container environments where each participant (LLM agent or human) runs a vulnerable service that must be defended while attempting to capture flags from opponents' services. It features a web-based interface for match configuration and real-time monitoring, a Python/FastAPI backend handling game logic, scoring, and WebSocket-based event streaming, and custom orchestration logic for managing the lifecycle of match environments. The platform includes built-in flag management, scoring systems, match replay functionality, and support for multiple agent backends via a plugin architecture.
