Atheris is a coverage-guided fuzzer for CPython that treats Python as a first-class fuzzing target, enabling rapid discovery of crashes and logic errors in pure-Python code and native extensions. It hooks into Python’s interpreter to collect fine-grained coverage and uses that signal to evolve inputs, pushing programs into previously unexplored code paths. Because many Python libraries are thin wrappers over C/C++ code, Atheris is equally adept at surfacing memory safety issues in extension modules compiled with sanitizers. ...

The Fuzzer Test Suite is a collection of real-world, bug-rich targets used to evaluate and compare fuzzers under controlled conditions. Rather than synthetic micro-benchmarks, it packages build scripts, corpora, and known-crash oracles so fuzzer authors can measure time-to-crash, coverage growth, and stability. Each target is configured to integrate with common sanitizers, ensuring memory safety bugs surface with precise diagnostics.

Simple Fuzzer is a simple fuzzing framework which allows rapid development of protocol fuzzers for blackbox testing. It can fuzz across networks using TCP/UDP, IP4/IP6, and can be extended via plugins to perform in-depth fuzzing.
