Artifact Keeper serves as a self-hosted universal software artifact repository that consolidates container images, application libraries, and infrastructure bundles under a unified management control plane. Software development teams can publish and resolve dependencies using their existing build tools, including Docker, Helm, npm, PyPI, Maven, Cargo, NuGet, and Terraform without installing proprietary client plugins. Remote repositories act as transparent pull-through caching proxies for public upstreams like Docker Hub and PyPI, accelerating internal CI/CD build speeds while insulating production pipelines from external registry outages. Virtual repositories combine multiple local, remote, and third-party endpoints into single URLs, resolving packages across prioritized internal teams and public registries automatically. Automated security scanners evaluate incoming packages for Common Vulnerabilities and Exposures using Trivy and Grype engines, assigning letter grades and enforcing quarantine policies to block vulnerable binaries before production release. Administrators can sign package metadata with cryptographic GPG keys, configure peer mesh replication across geographic regions, and manage team permissions using OpenID Connect, SAML, and granular access tokens. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
