Fuddly is a fuzzing and data manipulation framework that utilizes a graph-based data model to facilitate complex data format representation, manipulation, and fuzzing automation. Its primary use case is in testing software systems through generation and mutation strategies, with notable features including target abstraction, independent monitoring probes, replay and logging capabilities, and a scenario infrastructure for modeling protocol logic. The framework provides an intuitive command-line interface and supports advanced data transformation through custom operators.
