Pyston v1 was a faster, highly compatible implementation of the Python programming language, focused on improving runtime performance. This repository is the archived home of the old v1 code, which has been superseded by Pyston v2 in a separate repository.

Use cases

  • run python code faster without changing source
  • speed up cpu-bound python workloads
  • drop-in replacement for cpython with better performance
  • explore jit techniques for python
  • study the old pyston v1 codebase

When to choose

  • you specifically need the historical pyston v1 code for research or archaeology

When to avoid

  • you want the actively maintained Pyston v2 implementation
  • you need a supported Python interpreter for production
  • you expect updates or new releases from this repository
