## What it is
Sonatype Nexus Repository is a binary repository manager that serves as the single source of truth for internal and third-party build artifacts, components, and packages. The open-source Core codebase supports Maven, raw, and APT formats with an embedded H2 database, while the free Community Edition adds npm, Docker, NuGet, PyPI, Cargo, and more with optional PostgreSQL and Kubernetes deployment.

## Use cases
- host a private maven repository for internal libraries
- proxy and cache npm packages behind a corporate firewall
- self-host a docker registry for CI/CD pipelines
- store and distribute build artifacts centrally
- cache pypi packages to speed up builds
- manage apt package repositories for internal tooling
- set up an artifact repository for kubernetes deployments

## When to choose
- you need a centralized, self-hosted artifact repository for multiple package formats
- you want to proxy and cache public package registries for faster, more reliable builds
- you need role-based access control and cleanup policies for binaries
- you want a free, mature repository manager with broad CI/CD integrations

## When to avoid
- you only need a single-format registry with minimal overhead (e.g., a plain Docker registry)
- you require enterprise features like high availability, SSO, or official support without a paid license
- you want a lightweight cloud-native solution and cannot run a JVM-based server

## Facets
- artifact type: application
