I create open-source fuzzing solutions with the goal of being general but still easily customisable to use without or as less coding as possible. Such projects are:

• Grammarinator is a structure-aware/grammar-based input generator guided by ANTLRv4 parser grammars. It enables to fuzz hundreds of file formats with reusing existing grammars.

• Fuzzinator that can be used to build custom fuzzing workflows by writing configuration files only or by defining custom building blocks. A collection of predefined configuration set is available from the fuzzinator-configs repository.

• Automatic test case reducers to minimize failing input files:

  • Picire: structure-unaware (line and/or character based) reducer.
  • Picireny: structure-aware (ANTLRv4 grammar) based reducer.

With your support I could stay at home to work on what I love while being with those who I love to help securing what you love. ❤️
