ClusterFuzz

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 which help seamlessly integrate fuzzing into a software project's development process:

• Highly scalable. Can run on any size cluster (e.g. Google's instance runs on 30,000 VMs).
• Accurate deduplication of crashes.
• Fully automatic bug filing, triage and closing for various issue trackers (e.g. Monorail, Jira).
• Supports multiple coverage guided fuzzing engines (libFuzzer, AFL and Honggfuzz) for optimal results (with ensemble fuzzing and fuzzing strategies).
• Support for blackbox fuzzing.
• Testcase minimization.
• Regression finding through bisection.
• Statistics for analyzing fuzzer performance, and crash rates.
• Easy to use web interface for management and viewing crashes.
• Support for various authentication providers using Firebase.
