## What it is
The Google sanitizers repository hosts documentation and helper code for AddressSanitizer, ThreadSanitizer, MemorySanitizer, LeakSanitizer, and related dynamic analysis tools for C/C++ code. The repository is archived; the sanitizer runtimes now live in the LLVM project.

## Use cases
- detect memory errors like buffer overflows and use-after-free in C/C++ programs
- find data races and deadlocks in multithreaded code
- catch uses of uninitialized memory
- detect memory leaks in native applications
- instrument the Linux kernel with KASAN/KMSAN/KCSAN
- run undefined behavior checks with UBSan

## When to choose
- you need historical documentation or helper code for the sanitizers
- you want to understand how AddressSanitizer or ThreadSanitizer work

## When to avoid
- you need the actual sanitizer runtimes - use LLVM or GCC directly
- you want to file bugs or get new features - the repo is archived and unmaintained
- you need hardware-assisted sanitizers like HWASAN - go to the LLVM project

## Facets
- artifact type: library
