mimalloc is a compact general purpose allocator with excellent performance.

Memkind is an easy-to-use, general-purpose allocator which helps to fully utilize various kinds of memory available in the system, including DRAM, NVDIMM, and HBM

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

This is the user space slab memory allocator, umem, first available in Solaris 9. (mirror of: codeberg.org/gregburd/libumem)

Public domain cross platform lock free thread caching 16-byte aligned memory allocator implemented in C

Custom memory allocators in C++ to improve the performance of dynamic memory allocation

A library for constructing allocators and memory pools. It also contains broadly useful abstractions and utilities for memory management. UMF allows users to manage multiple memory pools characterized by different attributes, allowing certain allocation types to be isolated from others and allocated using different hardware resources as required.
