About This Tool

The tool analyzes a Python package's distribution model to identify bottlenecks in packaging, dependencies, and build metadata. It evaluates wheel sizing, sdist options, and compatibility across Python versions. It computes metrics such as installation time potential, footprint, and repeatability score. It then provides prioritized recommendations and concrete changes that minimize install latency and risk during packaging and deployment. Benefits include faster user installs, reduced CI time, and more reliable releases on PyPI. It is designed for maintainers, DevOps, and build engineers who manage Python packages and want measurable improvements. Core value lies in turning packaging signals into actionable steps, not in code optimization. Use cases include pre-release audits, migration to modern packaging formats, and optimizing dependency graphs for downstream projects.

How to Use

Provide inputs: package metadata, current dependency graph, and packaging config.
Run analysis: start the optimization scan with optional advanced rules.
Review results: examine prioritized recommendations, metrics, and impact estimates.
Apply changes: update packaging config and re-run validation in CI.
Validate outcomes: confirm builds and installations across target environments.

Frequently Asked Questions

Find Quick Answers

What does the PyPI Optimizer analyze?

It analyzes packaging structure, dependency graphs, wheel sizing, build metadata, version constraints, and cross-version compatibility to estimate install performance and reproducibility. It does not modify code, only packaging guidance.

What inputs are required?

Inputs include package name, current version, Python versions to support, dependencies with constraints, and current packaging configuration. Optional build tooling data can improve accuracy.

Does it automatically change my package?

No. It provides recommendations and impact estimates. Changes must be applied by the developer in the packaging configuration and verified locally or in CI.

What standards or regions apply?

It follows Python packaging standards (PEP 517/518), PyPI distribution practices, semantic versioning, and common CI packaging workflows to ensure broad compatibility.
