An AI-powered wrapper for ffuf that automatically suggests relevant file extensions for web fuzzing based on target URL analysis and response headers. Checked October 2026. ## What is ffufai? ffufai is an AI-powered wrapper for the web fuzzer ffuf that automatically suggests file extensions for fuzzing based on the target URL and its headers. The tool integrates with ffuf and uses either OpenAI's GPT or Anthropic's Claude AI models to generate relevant file extensions for more effective fuzzing. It acts as a pass-through wrapper, accepting all standard ffuf parameters while adding AI-enhanced extension suggestion capabilities. Key features include: - Seamless integration with existing ffuf workflows - Automatic suggestion of relevant file extensions based on target analysis - Support for both OpenAI and Anthropic AI models - Pass-through of all ffuf parameters and options - Additional configuration options for ffuf path specification and extension limit settings The tool requires Python 3.6+ and ffuf to be installed on the system. It analyzes the target URL and response headers to provide contextually relevant file extension suggestions, aiming to improve the efficiency of web application fuzzing activities by reducing manual guesswork in extension selection.
