uv is a fast Python package and project manager, written in Rust. It can be used instead of pip, pip-tools, pipx, poetry, pyenv, and virtualenv tools. uv provides a complete ecosystem for managing Python projects, allowing you to add dependencies, manage tools, run scripts, and more. In short, from installing Python to building Python applications, uv makes the process faster and easier. One of the best features of uv is its compatibility with the pip tool. This means that you just need to add "uv" in front of your command and all of your previous commands will work out of the box.
