# OSS-Fuzz: Continuous Fuzzing for Open Source Software
2016-10-25 21:31:45 +00:00
[Fuzz testing ](https://en.wikipedia.org/wiki/Fuzz_testing ) is a well-known
2019-08-08 14:12:25 +00:00
technique for uncovering programming errors in software.
2019-08-09 19:35:14 +00:00
Many of these detectable errors, like [buffer overflow ](https://en.wikipedia.org/wiki/Buffer_overflow ), can have serious security implications. Google has found [thousands] of security vulnerabilities and stability bugs by deploying [guided in-process fuzzing of Chrome components ](https://security.googleblog.com/2016/08/guided-in-process-fuzzing-of-chrome.html ),
2019-08-09 19:24:43 +00:00
and we now want to share that service with the open source community.

In cooperation with the [Core Infrastructure Initiative ](https://www.coreinfrastructure.org/ ),
OSS-Fuzz aims to make common open source software more secure and stable by
2019-08-08 14:12:25 +00:00
combining modern fuzzing techniques with scalable,
2016-11-19 00:47:25 +00:00
distributed execution.

2019-08-08 14:12:25 +00:00
We support the [libFuzzer ](http://llvm.org/docs/LibFuzzer.html ) and [AFL ](http://lcamtuf.coredump.cx/afl/ ) fuzzing engines
in combination with [Sanitizers ](https://github.com/google/sanitizers ), as well as
[ClusterFuzz ](https://github.com/google/clusterfuzz ),
a distributed fuzzer execution environment and reporting tool.
Currently, OSS-Fuzz supports C and C++ code, though other languages supported by [LLVM ](http://llvm.org ) may work too.
