aptly vs Verdaccio

aptly manages Debian package repositories and publishes controlled package sets for systems that use apt. It can mirror remote repositories, maintain local repositories, pull selected package versions with dependencies, and publish repositories. Immutable snapshots can be compared, merged, filtered, searched and used to create repeatable package environments with controlled changes and rollback to earlier versions. Mirroring supports regular and flat repositories over HTTP(S) and FTP, with filters for architectures, components and packages. Packages from mirrors and local repositories are kept in a deduplicated pool that can be searched and cleaned up. Repositories can be published to local storage, Amazon S3, OpenStack Swift, Azure or JFrog Artifactory Storage, and signed with a user-provided GnuPG key. aptly is free and available as a CLI tool and HTTP REST service. Its REST API has no authentication or protection, and the embedded web server is described as unsuitable for production use.

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.
