Cloudsmith vs Verdaccio

Cloudsmith has no write-up on Specifiction yet; its figures are above.

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.
