Pyjion – A Python JIT Compiler

• Pyjion

  10 1,169 9.7 C++

  Pyjion - A JIT for Python based upon CoreCLR (by tonybaloney)

  This is the first time I've learned of this. How it compares to PyPy:

  > PyPy is an implementation of Python with its own JIT. The biggest difference compared to Pyjion is that PyPy doesn't support all C extension modules without modification unless they use CFFI or work with the select subset of CPython's C API that PyPy does support. Pyjion also aims to support many JIT compilers while PyPy only supports their custom JIT compiler.

  Apparently it's originally a Microsoft project, and it requires .NET

• Numba

  50 7,492 9.9 Python

  NumPy aware dynamic Python compiler using LLVM

  

  I wonder how this compares with Numba [1]. I've used Numba on occasion to speed up numerical heavy Python code (although I would normally prefer to use Julia when possible). It can be quite finicky, but when it works in nopython mode it usually provides a significant speedup.

• Cython

  35 7,019 9.7 Python

  The most widely used Python to C compiler

  

  Why is there so little mention of https://cython.org/ ?

  It's very fast, it compiles to C code, then compiles the C code with a normal compiler.

• graalpython

  8 887 9.9 Python

  A Python 3 implementation built on GraalVM

  

  Isn't this what the GraalVM [1] guys are also trying to do? Seems like today the competition is between who is more polyglot than the other, JVM, CLR or WASM.

  1 89 0.0 Python

  A Nintendo Entertainment System (NES) emulator in Python and Cython. (by jameskmurphy)

  For example here's a Python project modified to work well on Cython - I think that's pretty substantially modified.

• falcon

  4 8,762 8.2 Python

  The no-nonsense web data plane API and microservices framework for Python developers, with a focus on reliability, correctness, and performance at scale.

  

  And here's a project that's mostly Python, and optionally uses Cython https://github.com/falconry/falcon
