foonathan/memory is a C++ library providing STL-compatible memory allocators built around a simpler RawAllocator concept. It offers multiple allocator implementations (pools, stacks, temporary allocators) plus adapters to interoperate with standard STL allocators.

Use cases

• use custom memory pools with STL containers
• share one allocator across multiple types in C++
• allocate temporary memory on the stack like alloca portably
• track and debug memory leaks and double-frees
• improve allocation performance in games or embedded systems
• use allocators with smart pointers

When to choose

• you need faster or pooled allocation for STL containers
• you want stateful, type-erased allocators that work with the standard library
• you develop on freestanding or embedded environments with custom memory
• you need memory debugging features like leak or overflow checks

When to avoid

• your project has no allocation performance or control requirements
• you only need C++17 polymorphic memory resources
• you cannot build with CMake or an older toolchain
