AFL++ is a state-of-the-art fuzzer, and #1 in benchmarks. It was originally based on AFL. Today it comes with qemu 5.1, collision-free coverage, enhanced laf-intel & redqueen, AFLfast++ power schedules, MOpt mutators, unicorn_mode, and a lot more!
Angora is a mutation-based fuzzer. The main goal of Angora is to increase branch coverage by solving path constraints without symbolic execution.
