Verdaccio

Verdaccio is a Node.js private npm registry for local or self-hosted package publishing and installation. It starts without a separate database by using its own small database, and it can proxy other registries such as npmjs.org while caching downloaded modules along the way.

It supports standard npm client workflows for private packages, including install, update, publish, unpublish, dist-tags, deprecation, user registration, password changes, ownership transfer, tokens, search, ping, starring, and npm or yarn audit. Storage can be extended through community plugins for services such as Amazon S3 and Google Cloud Storage, or through custom plugins.

Verdaccio runs from npm and as a Docker container, with Docker tags available. Version 6 requires Node.js 18 or higher, while the current development branch notes Node.js v24 as the minimum. The software is MIT licensed.
