OSS-Fuzz is Google's free continuous fuzzing service for open source software, combining fuzzing engines like libFuzzer, AFL++, and Honggfuzz with sanitizers and distributed execution via ClusterFuzz. It has helped find over 13,000 vulnerabilities and 50,000 bugs across 1,000+ projects since 2016.
Use cases
- find security vulnerabilities in my open source c/c++ library
- continuous fuzz testing for a rust or go project
- detect buffer overflows and memory bugs automatically
- set up fuzzing in ci for an open source project
- fuzz a java or python codebase for crashes
- run a self-hosted fuzzing service for closed source code
When to choose
- your open source project is written in C/C++, Rust, Go, Python, Java, JavaScript, or Lua and handles untrusted input
- you want free, scalable, continuously running fuzzing with bug reporting
- you want to catch memory-safety and stability bugs before attackers do
When to avoid
- your project is closed source and you don't want to self-host ClusterFuzz or ClusterFuzzLite
- your code has no meaningful input parsing surface for fuzzers to exercise
- you need quick one-off fuzzing without build integration effort
