"Blazing-fast installs uv is routinely 10-100× faster than pip (and often faster than Poetry or pipenv too). Dependency resolution and wheel installation that used to take seconds or minutes now finish in the blink of an eye. One tool to rule them all uv replaces pip + venv + pip-tools + pipx + virtualenv + pyenv in a single binary. You get dependency resolution, lockfiles, virtual-environment management, isolated global tool installation, Python version management, and even script running - all through the same uv command."
"Virtual environments are created and populated automatically (no more python -m venv .venv && source .venv/bin/activate). A deterministic file is generated on the first uv sync or uv lock. Running scripts with uv run always uses the correct environment, even if you delete .venv, uv silently recreates it in milliseconds. Project scaffolding, building, and publishing are also built-in, so you can go from idea to published package without ever leaving uv."
uv accelerates Python dependency resolution and environment management through a Rust-based resolver and installer, aggressive global wheel caching, parallel downloads and builds, and version-pinned resolution that minimizes backtracking. Benchmarks show uv is 8–10× faster than pip without cache and 80–115× faster with a warm cache. uv consolidates pip, venv, pip-tools, pipx, virtualenv, and pyenv into a single binary that manages lockfiles, virtual environments, global tools, Python versions, and script execution. Virtual environments are created and repopulated automatically, deterministic lock files are generated, project scaffolding and publishing are built-in, and uv silently recreates deleted environments in milliseconds.
