Hex vs uv

Hex is a package manager for the BEAM ecosystem, including Elixir and Erlang. Its services include an HTTP API, a website, a package and index repository, HexDocs, Mix integration, and other components. Packages work with Mix, Rebar, and erlang.mk, and the site provides usage guidance for Gleam. Developers can fetch dependencies without creating an account.

Organizations can publish and retrieve private packages and manage which users can access them. Free organizations can publish public dependency policies; paid organizations can make policies private and apply them to public and private packages. A private package can depend only on packages in its organization’s repository and the global hexpm repository. Documentation explains how to build and serve a repository on infrastructure an organization operates. Hex supports organization authentication keys for CI, and its source code is licensed under the Apache 2 License. The Open Source plan is free. Private Packages are listed at $9 / user / month, with an annual option at $90 / per user / per year. Enterprise pricing is by contacting sales. Hex lists API, self-hosted, and web platforms.

uv is a Python package and project manager for Linux, macOS, and Windows. Written in Rust, it manages dependencies and environments, with lockfiles and workspaces, and can install, list, pin, or uninstall Python versions. It also runs scripts with dependencies and runs or installs command-line tools from Python packages. Its pip-compatible interface is intended to cover work done by tools such as pip, pip-tools, pipx, poetry, pyenv, twine, and virtualenv, though its commands do not exactly match those tools. The documentation describes uv as 10–100x faster than pip. It supports source distributions, wheels, requirements.txt, and pylock.toml, as well as offline installation and private registry authentication. For package selection, its default first-index strategy limits candidates to the first index where a package is found. Credentials are not stored in uv.lock, but uv currently stores them in a plaintext file; native system secret storage is an experimental preview. The free plan is free.
