In their own words
NuGet
NuGet is a package manager for .NET projects, with tools to create and consume packages and the NuGet Gallery as a central repository. Packages use the .nupkg format and can include compiled code, related files and a descriptive manifest; .snupkg is also supported. NuGet resolves dependency graphs and records package identifiers and versions so projects can restore dependencies across machines and build servers. PackageReference and packages.config are supported, with PackageReference required for .NET SDK-style projects. Developers can manage packages in Visual Studio or use the dotnet CLI and nuget.exe. Packages may be hosted in private cloud locations, private networks or local file systems. Restore can check dependencies against configured vulnerability sources and report warnings. NuGet also supports lockfiles, offline installation, private registry authentication and package signatures. The service is free, and the Gallery code is open source under Apache 2.0. The dotnet CLI works on Windows, macOS and Linux; nuget.exe runs on Windows and can run on macOS and Linux with Mono, with limitations.
uv
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.
