boofuzz is a Python-based network protocol fuzzing framework and the successor to the Sulley Fuzzing Framework. It provides data generation, failure detection via instrumentation, target reset, and thorough test data recording for building fuzzer scripts.

Use cases

• fuzz network protocols for vulnerabilities
• fuzz a TCP or UDP service with malformed inputs
• perform serial or ethernet-layer fuzzing
• find crashes in a custom binary protocol parser
• export fuzzing test results to CSV for analysis
• build a custom fuzzer script in Python

When to choose

• you need an actively maintained open-source protocol fuzzer
• you want scriptable, extensible fuzzing in Python
• you need instrumentation, target reset, and test recording built in
• you're migrating from the unmaintained Sulley framework

When to avoid

• you need file-format or in-process fuzzing rather than network protocols
• you want a GUI-driven fuzzer with no scripting
• your project requires a permissive license (boofuzz is GPL-2.0)
