Best Package Managers for Python

Store and share artifacts across accounts, with appropriate levels of access granted to your teams and build systems. Reduce overhead from setup and maintenance of an artifact server or infrastructure with a fully managed service. Only pay for software packages stored, number of requests made, and data transferred out of Region with pay-as-you-go pricing. Configure CodeArtifact to fetch from public repositories such as the npm Registry, Maven Central, Python Package Index (PyPI), and NuGet. Securely share private packages across organizations by publishing them to a central organizational repository. Build automated approval workflows with CodeArtifact APIs and Amazon EventBridge, with visibility into your packages using AWS CloudTrail. Pull dependencies from CodeArtifact in AWS CodeBuild and publish new versions of your private packages secured with AWS Identity and Access Management (IAM).

Artifact Registry is Google Cloud’s unified, fully managed package and container registry designed for high-performance artifact storage and dependency management. It centralizes host­ing of container images (Docker/OCI), Helm charts, language packages (Java/Maven, Node.js/npm, Python), and OS packages, offering fast, scalable, reliable, and secure handling with built-in vulnerability scanning and IAM-based access control. Integrated seamlessly with Google Cloud CI/CD tools like Cloud Build, Cloud Run, GKE, Compute Engine, and App Engine, it supports regional and virtual repositories with granular security via VPC Service Controls and customer-managed encryption keys. Developers benefit from standardized Docker Registry API support, comprehensive REST/RPC interfaces, and migration paths from Container Registry. Daily updated documentation includes quickstarts, repository management, access configuration, observability tools, and deep-dive guides.
