LibAFL

LibAFL is a modular fuzzing library that implements features from AFL-based fuzzers like AFL++. Unlike traditional fuzzers, LibAFL provides all functionality in a modular and customizable way as a Rust library. It can be used as a drop-in replacement for libFuzzer or as a library to build custom fuzzers from scratch.

When to Use

Choose LibAFL when:

• You need custom mutation strategies or feedback mechanisms
• Standard fuzzers don't support your target architecture
• You want to implement novel fuzzing techniques
• You need fine-grained control over fuzzing components
• You're conducting fuzzing research
