ClusterFuzz is a scalable fuzzing infrastructure that finds security and stability issues in software.

Google uses ClusterFuzz to fuzz all Google products and as the fuzzing backend for OSS-Fuzz.

ClusterFuzz provides many features to seamlessly integrate fuzzing into a software project’s development process:


As of September 2020, ClusterFuzz has found 25,000+ bugs in Google (e.g. Chrome) and ~22,500 bugs in over 340 open source projects integrated with OSS-Fuzz.
