Aube vs vlt

Aube is an open-source Node.js package manager written in Rust for Linux, macOS, and Windows. Its aubr command checks dependencies before running a project script and installs those that are missing or stale. Aube reads and writes supported pnpm, npm, Yarn, and Bun lockfiles, while its content-addressable store shares package directory trees across projects and worktrees. For one-off tools, aubx uses a local binary when available or installs the tool in a throwaway project. Workspaces, filters, and catalogs can be configured through pnpm-workspace.yaml or aube-workspace.yaml, and commands can use a project-pinned Node version. Security checks consider publishing evidence, release age, and known malicious packages during version selection. Dependency lifecycle scripts need project approval or built-in trust, with explicit denials taking precedence. Optional integrity verification checks fetched registry tarballs against recorded values. Installation options include mise, Homebrew, npm, Cargo, distribution packages, and source builds. Aube also provides embedding integrations for Rust, Node-API hosts, and C ABI consumers, plus a GitHub Action. Yarn Plug'n'Play projects are not supported and require a node_modules linker.

vlt provides npm-compatible JavaScript package registries for teams publishing scoped or private packages and managing organizations and access. It is available as a web service or self-hosted, with a client compatible with vlt, npm, pnpm, yarn, bun, deno and CI publishing. Registry infrastructure uses caching and smaller payloads. Developers can inspect resolved dependency graphs, trace why dependencies exist and query them with selector syntax; the CLI handles installation, publishing, configuration, execution and dependency queries. The registry says it blocks known malware and high-risk software through advisory and malware scanning across a safe npm mirror. Lifecycle scripts are restricted or disabled by default, and risky behavior needs explicit approval. Socket integration identifies dependency security risks. The VSR private registry can run locally or in CI with granular access tokens. TLS 1.2 or later and MFA for high-risk systems are stated security controls. Free costs nothing with 2GB storage and delivery, upstream proxy, user and token management and community support. Pro costs $8 a month, billed annually; Premium costs $20 a month, billed annually; Enterprise costs $79 a month, billed annually. Enterprise+ pricing is custom.
