# syzkaller - kernel fuzzer
|
|
|
|
[](https://travis-ci.org/google/syzkaller)
|
|
|
|
`syzkaller` is an unsupervised coverage-guided kernel fuzzer. `Linux` kernel fuzzing has the most support, `akaros`, `freebsd`, `fuchsia`, `netbsd` and `windows` are supported to varying degrees.
|
|
|

The project mailing list is [syzkaller@googlegroups.com](https://groups.google.com/forum/#!forum/syzkaller).

## Documentation
|
|
|
|
Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well.
|
|
Most of the documentation at this moment is related to the Linux kernel.
|
|
For other OS kernels check: [Akaros](docs/akaros/README.md), [FreeBSD](docs/freebsd.md), [Fuchsia](docs/fuchsia.md), [NetBSD](docs/netbsd.md), [Windows](docs/windows.md).
