PyPI GitHub Release License: MIT Python CI Benchmarks Docs arXiv

Zero-dependency, single-file Python implementations of popular libraries — stdlib only, benchmarked for performance parity, Python 3.10+.

Overview

Each module is a self-contained single file that you can copy directly into your project. No pip install required.

Philosophy

  • Zero external dependencies — only Python standard library
  • Single file — copy one .py file into your project
  • Python 3.10+ — leverages modern Python features
  • Correctness first — apple-to-apple tests against reference libraries
  • Performance parity — benchmarked against popular alternatives (live dashboard)
