What is Artifact Repository?

A centralized storage system for build artifacts like compiled binaries, packages, and container images used in CI/CD pipelines.

Artifact repositories store versioned build outputs — JARs, npm packages, Python wheels, Docker images, Helm charts, and more. They serve as the bridge between CI (build) and CD (deploy) stages.

Popular solutions include JFrog Artifactory (universal), Nexus Repository (multi-format), GitHub Packages, and cloud-native registries. Features include proxying remote repositories, vulnerability scanning, retention policies, and access control.
