Boofuzz fuzzing framework

Text to Speech Demo

Boofuzz is a fork of and the successor to the Sulley fuzzing framework. Besides numerous bug fixes, boofuzz aims for extensibility, with the eventual goal of being able to fuzz literally anything. Sulley has been the preeminent open source fuzzer for some time, but has fallen out of maintenance.

Like Sulley, boofuzz incorporates all the critical elements of a fuzzer:

  • Easy and quick data generation.
  • Instrumentation, AKA failure detection.
  • Target reset after failure.
  • Recording of test data.


Unlike Sulley, boofuzz also features:

  • Much easier install experience!
  • Support for arbitrary communications mediums.
  • Extensible instrumentation/failure detection.
  • Better recording of test data.
  • Far fewer bugs.


Sulley is affectionately named after the creature from Monsters Inc., because of his fuzziness.
