garbage-collector

Mono open source ECMA CLI, C# and .NET implementation.

Visualise Go runtime metrics in real time

Eclipse OpenJ9: A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR (https://github.com/eclipse/omr) and combines with the Extensions for OpenJDK for OpenJ9 repo.

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

Detect and fix struct field alignment to reduce memory usage in Go programs

🌀 A brand-new compiler that allows practical application development using R7RS Scheme. We provide modern features and a stable system capable of generating fast native binaries.

The Memory Pool System

Cross-platform virtual machine for the Smalltalk implementations Squeak and Cuis

Python 3.14, compiled to metal — JIT & AoT native compiler and runtime in Rust. Cranelift backend, ruff parser, Green Tea GC, byte-exact differential testing against CPython.

Memory Management ToolKit

Clean up (delete) Kubernetes resources after a configured TTL (time to live)

A single-header incremental garbage collector library

Single-pass SSA bytecode compiler and threaded-code stack VM for a Python subset. NaN-boxed values, inline caching, super-instruction fusion, pure-function memoization, mark-sweep GC, interpreter snapshots, and coverage-guided fuzzing. Runs in the browser as a WebAssembly module, or in the CLI as a script, a standalone binary, or a pool of workers.

🌟This is a pure C++ implementation of Java Virtual Machine (only Java 8 is supported). Inspired by Hotspot In Action.

[yvm] low performance garbage-collectable jvm

An ergonomic tracing garbage collector that supports mark 'n sweep garbage collection

SGCL is a C++20 application framework with a concurrent, pause-free garbage collector: pointers, containers, lock-free structures, Go-style coroutines and channels.

Host of debugging-related extensions such as post-mortem tools or WinDBG extensions

Scale down or delete unneeded workload after work hours based on conditions

Heapothesys /hɪˈpɒθɪsɪs/ is a heap allocation JVM benchmark developed by the Amazon Corretto team.
