Compiler GitHub Repositories (2026) · Open Source Tools

Empowering everyone to build reliable and efficient software.

Translate GPU shaders and compute kernels between GLSL, HLSL, Metal, SPIR-V and Slang, from CUDA and HIP, and to WGSL, through the CrossGL IR

⚓ A collection of high-performance JavaScript tools.

A PHP-to-native compiler. Takes a subset of PHP - including eval() - and compiles it directly to native assembly, producing standalone binaries for macOS ARM64, Linux ARM64, and Linux x86_64. No VM, no external runtime, no dependencies: dynamic eval falls back to an optional statically linked interpreter.

Incremental rust builds up to 92x faster than cargo/rustc

The React Framework

Open source Python/CUDA C/C++ to SASS/CUDA Binary compiler (previously closed source by nvidia), ~16.5% faster than PyTorch CUDA API in ML tasks, tie PTXAS on ReLU, GeLU, Adam etc. Open for specific kernel optimization that break the existing categories further down into cases as well as architectural innovations.

Run compilers interactively from your web browser and interact with the assembly

⭐️ A friendly language for building type-safe, scalable systems!

A markup-based typesetting system that is powerful and easy to learn.

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

wazero: the zero dependency WebAssembly runtime for Go developers

🐉 Making Rust a first-class language and ecosystem for GPU shaders 🚧

web development for the rest of us

Nuitka is a Python compiler written in Python. It's fully compatible with Python 2.6, 2.7, 3.4-3.14. You feed it your Python app, it does a lot of clever things, and spits out an executable or extension module.

NumPy aware dynamic Python compiler using LLVM

Open Machine Learning Compiler Framework

Analyze Rust crates without touching compiler internals

An extremely fast CSS parser, transformer, bundler, and minifier written in Rust.

Simple, fast, safe, compiled language for developing maintainable software. Compiles itself in <1s with zero library dependencies. Supports automatic C => V translation. https://vlang.io
