LuaRocks vs Mamba

LuaRocks is a package manager for Lua, with LuaRocks.org hosting rocks and rockspecs for Lua modules. Its command line uses manifests to find packages, choose a version and platform match, and install the corresponding files locally. Rocks carry version dependency information, which LuaRocks uses to install dependencies and load the appropriate module version. Package collections can be organized through the root manifest, per-user manifests, or custom manifests; development versions are kept in a separate manifest and are not installed by default. LuaRocks supports offline installation and platforms including Linux, macOS, Windows, Unix, FreeBSD, and Cygwin. Module authors can register and upload a rockspec, then publish rock files for a version; the current release supports the `luarocks upload` command. The application is described as pure Lua with no library dependencies, though its current release uses helper tools. LuaRocks is free, with a listed price of free.

Mamba manages conda environments across Linux, macOS, Windows, API, and self-hosted setups. It creates and activates environments, installs packages, and runs commands inside them. It works with conda packages and supports most conda commands; its parallel downloads and libsolv solver speed package resolution. The framework includes the mamba command-line interface, the libmamba C++ library, micromamba, and Python bindings. Environment creation accepts text, Conda YAML, explicit, and conda-lock YAML specifications, and micromamba can install conda-lock files directly. The repoquery command searches repositories and can display direct, recursive, and reverse dependencies. Environments are self-contained prefixes that can manage native dependencies across programming languages. Mamba documents verification for package archives and extracted files, while repository index verification remains experimental. By default, it warns and asks for confirmation before transactions run package link scripts that can perform system operations. Mamba is free, open-source software under the BSD-3-Clause license, with lockfile support.
