Nexspence vs Verdaccio

Nexspence is a self-hosted artifact repository manager positioned as a replacement for other artifact repository managers. It supports 15 formats, including Maven, Docker, npm, PyPI, Go Modules, NuGet, Helm, Cargo, Apt, Yum, Conan, Raw, Conda, and Terraform. Hosted, Proxy, and Group repository types are available across formats, with format-specific exceptions. A one-command migration streams repositories, users, and artifacts from a live Nexus instance and is described as pausable and conflict-safe. Storage can use MinIO, AWS S3, Wasabi, or a local filesystem, with per-repository blob-store assignment. Identity options include OIDC/SSO providers, just-in-time provisioning, and group-to-role mapping. Security controls include LDAP, API tokens, JWT, fine-grained RBAC, and SSRF-protected outbound fetches. OSV.dev scanning covers Maven, npm, PyPI, and Cargo; Docker and OCI scanning requires an operator-supplied Trivy installation. Deployment options include Docker Compose, Helm/Kubernetes, and native packages or archives for Linux, macOS, and Windows. Nexspence is free at free and licensed under GNU AGPL v3 or later.

Verdaccio is a lightweight Node.js private proxy registry for organizations managing npm packages. It keeps private packages away from public registries, proxies sources such as npmjs.org, and caches downloaded modules. Multiple registries can be chained behind one endpoint, and teams can publish modified third-party packages locally under their existing names. npm, yarn, and pnpm clients are supported. Verdaccio can run self-hosted, with an official Docker image and Kubernetes Helm support. Its default storage uses the local file system and a small built-in database. Built-in htpasswd authentication and package access rules govern access, publishing, and unpublishing. JWT tokens may be configured with expiration, while legacy tokens are not designed to expire. Plugins extend authentication, middleware, storage, UI themes, and filtering. Installation requires Node.js, a package manager, and a modern browser; version 6.x requires Node.js 22 or later, and 7.x requires Node.js 24 or later.
