AFLplusplus

Community fork of American Fuzzy Lop fuzzer

About AFLplusplus

A community-driven fork of the American Fuzzy Lop instrumentation-guided fuzzer, used to discover security vulnerabilities and crashes in native programs through coverage-guided mutation of inputs. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
