SkillHub
SkillHub gives teams a private, npm-style registry for AI agent skills, so a useful skill package is published once, reviewed, versioned, and installed into a compatible agent from the command line. Upload a package from the web console, the CLI, or the REST API, pick PUBLIC, NAMESPACE_ONLY, or PRIVATE visibility, and track releases with semantic versions plus tags such as beta and stable. Team namespaces keep their own members with Owner, Admin, and Member roles and publishing policies, while full-text search filters by namespace, downloads, ratings, and recency and hides whatever a user may not see. Every submission enters a review queue: namespace admins approve or reject team skills, platform admins decide promotions to the global scope, and each governance action lands in the audit log. A built-in Skill Scanner inspects published packages and shows its report on the skill page, with optional behavioral, LLM, VirusTotal, and Cisco AI Defense engines. Members can star and rate skills, follow download counts, receive notifications, and report problem packages. Skill suites bundle several skills into one versioned collection with an entry skill, scoped API tokens serve the CLI and scripts, and the interface speaks English, Simplified Chinese, Russian, and Korean. Packages live on local disk or S3-compatible storage such as MinIO. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Verdaccio
Private npm packages without shipping code to the public registry or paying for npm Enterprise: Verdaccio is the standard lightweight, zero-config private registry and caching proxy. It runs as a single Node.js process with its own tiny embedded database; no external database is required to start. Point npm, yarn, or pnpm at it and everything behaves as expected: install, publish, unpublish, dist-tags, and deprecation all work against the standard npm endpoints. The uplink system is where it earns its keep: packages not found locally are fetched from configured upstreams (npmjs.org, yarn, JFrog, Nexus, or another Verdaccio), cached as tarballs, and served locally thereafter - cutting CI latency and surviving registry outages. Multiple uplinks chain for failover, and per-package glob patterns in config.yaml route scopes to specific upstreams while controlling access, publish, and unpublish rights per group. You can even override a public package by publishing a patched version under the same name locally. A plugin architecture swaps in auth backends (htpasswd default, LDAP and others available), storage drivers (S3, Google Cloud Storage), middleware routes, and metadata filters. With official Docker images and a Kubernetes Helm chart, it slots into any pipeline in minutes.
Nexus Repository
Trusted by millions of developers and integrated into CI/CD pipelines at organizations worldwide, Sonatype Nexus Repository is the industry-standard binary artifact repository manager that stores, organizes, and distributes software components across every major package ecosystem. Community Edition supports over 20 formats including Maven for Java builds, npm for JavaScript packages, Docker for container images, PyPI for Python libraries, NuGet for .NET assemblies, Helm for Kubernetes charts, Go modules, RubyGems, Cargo for Rust crates, Conda for data science environments, APT for Debian packages, Yum for RPM distributions, and Hugging Face for AI/ML models. Three repository types serve different needs: hosted repositories store internally-produced artifacts, proxy repositories cache remote registries like Maven Central, npmjs.org, and Docker Hub reducing bandwidth and improving build reliability, and group repositories aggregate multiple hosted and proxy repositories behind a single URL endpoint. The web UI provides component browsing and search, repository configuration, blob store management with configurable cleanup policies, and direct artifact upload via drag-and-drop. Role-based access control enforces fine-grained permissions per repository with configurable security realms, while the comprehensive REST API enables automated repository provisioning, component management, and integration with Jenkins, GitHub Actions, GitLab CI, and Azure DevOps. External PostgreSQL database support enables Kubernetes deployments with improved backup, restore, and horizontal scaling capabilities.
