What aptly is

aptly manages Debian package repositories and publishes controlled package sets for systems using 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 using a user-provided GnuPG key that must be generated before publishing. aptly is free to try as a CLI tool and HTTP REST service, with downloads listed for Linux, macOS, and FreeBSD. Its REST API has no authentication or protection, so the documentation warns against internet exposure without a proxy that adds HTTPS and authentication. The embedded aptly serve web server is described as unsuitable for production use.
