aptly vs Nexspence

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.

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.
