Top 12 malloc Open-Source Projects

  • snmalloc

    Message passing based allocator

    • Project mention: Snmalloc: A Message Passing Allocator | news.ycombinator.com | 2023-10-11

    https://github.com/microsoft/snmalloc#snmalloc mentions two biggest motivations as:

    > Allocations on one thread are freed by a different thread

    I can imagine one use-case for this: a task that is scheduled from and executed by a work-stealing thread-pool can allocate memory in one thread but by design there's no guarantee that the memory will be necessarily freed from that exact thread. Would that be a good use-case for snmalloc?

    > Deallocations occur in large batches

    This sounds much like a bump allocator use-case but which can do this exact thing by calling a single munmap(addr, len) and unmap multiple allocations all at once.

  • hardened_malloc

    Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain more portability / integration over time.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • Hoard

    The Hoard Memory Allocator: A Fast, Scalable, and Memory-efficient Malloc for Linux, Windows, and Mac.

  • Heap-Layers

    Heap Layers: An Extensible Memory Allocation Infrastructure

  • lwmem

    Lightweight dynamic memory manager library for embedded systems with memory constraints. It implements malloc, calloc, realloc and free functions

  • o1heap

    Constant-complexity deterministic memory allocator (heap) for hard real-time high-integrity embedded systems. There is very little activity because the project is finished and does not require further changes.

  • metamalloc

    Single header template based general purpose memory allocation library for Linux & Windows. Repo also provides a live http memory profiler as a separate single-header with no dependencies

    • Project mention: Metamalloc: Single-header template based general purpose memory allocator lib | news.ycombinator.com | 2024-01-16

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • mm-go

    Generic manual memory management for golang

  • memorymanager

    A simple, thread-safe memory manager for 64bit C++ applications and games. Focus is on preventing heap fragmentation in the absence of good virtual memory management, at the cost of wasting some memory. It works by globally overriding the new and delete operators.

    the only person to have suggested a solution linked me this: https://github.com/schulkinator/memorymanager

  • go-interface-values

    When storing a value in a Go interface allocates memory on the heap.

  • RTSHA

    Real Time Safety Heap Allocator

    • Project mention: Rtsha v1.0 | news.ycombinator.com | 2023-11-19

  • Listlib

    Listlib is a simple, unsafe, slow and easy to use library that implements a heap-allocated vector of any type
