Open-source alternatives to Memory Allocators

Smart pointers for the (GNU) C programming language

STL compatible C++ memory allocator library using a new RawAllocator concept that is similar to an Allocator but easier to use and write.

Tcmalloc is a high-performance C++ memory allocator and runtime library designed to manage heap memory for large-scale services. It functions as a thread-caching memory allocator that reduces lock contention in multi-threaded applications to maintain stability and performance during concurrent workloads. The project focuses on high-concurrency memory allocation and multithreaded application scaling. It employs a strategy of providing per-thread caches to ensure fast memory access and improve the throughput of parallel programs in low-level system programming environments. The library manages

The Boehm-Demers-Weiser conservative C/C++ Garbage Collector (bdwgc, also known as bdw-gc, boehm-gc, libgc)

jemalloc is a general purpose C memory allocator designed as a replacement for the standard library malloc and free functions. It is a multi-threaded allocation library that emphasizes fragmentation avoidance and scalable concurrency for high-performance applications. The project reduces lock contention by using multiple independent memory arenas and thread-local cache layers. It minimizes latency by offloading the reclamation of unused memory pages to asynchronous background threads and utilizes huge page metadata storage to reduce translation lookaside buffer misses. The system includes a
