LibAFL # The LibAFL fuzzer implements features from AFL-based fuzzers like AFL++. Similarly to AFL++, LibAFL provides better fuzzing performance and more advanced features over libFuzzer. However, with LibAFL, all functionality is provided in a modular and customizable way—in fact, LibAFL is a library that can be used to implement custom fuzzers. Because LibAFL is a library, there is no single-line command to install LibAFL like there is with libFuzzer (apt install clang) and AFL++ (apt install afl++).
