Here's a detailed comparison between UV Package Manager and Conda:
Feature | UV Package Manager | Conda |
---|---|---|
Primary Language | Rust | Python |
Package Format | PyPI (wheel, source) | Conda packages (binary) |
Speed | 🚀 Extremely fast (Rust-based) | Moderate (slower dependency resolution) |
Dependency Resolution | Fast, uses modern resolver | Slower, but powerful for binary packages |
Environment Management | ✅ Yes (via uv venv ) |
✅ Yes (conda create , conda activate ) |
Lockfile Support | ✅ Yes (uv.lock ) |
❌ Not built-in (via external tools like conda-lock ) |
Python-only? | ✅ Yes, focuses only on Python packages | ❌ No, supports R, C/C++, Julia, etc. |
Offline Caching | ✅ Yes (uv cache ) |
✅ Yes |
Cross-platform | ✅ Yes | ✅ Yes |
Virtual Environment Type | Uses .venv/ (standard Python venv) |
Conda environments |
Third-party Libraries | From PyPI (e.g. requests , numpy ) |
From Conda channels (defaults , conda-forge , etc.) |
Binary Packages | ❌ No (uses wheels/compilation if needed) | ✅ Yes (precompiled binaries, no compiler required) |
Ease of Use | Simple & clean UX with CLI | Slightly more complex CLI |
Project Scope | Python development only | Full data science stack (R, CUDA, etc.) |
Installation Size | Very lightweight (~single binary) | Heavyweight (~500MB+ for full Conda) |
Best Use Case | Python dev, apps, fast installs, reproducible projects | Scientific computing, mixed language environments |
✅ Use uv
if:
You want blazing fast dependency management for Python-only projects.
You prefer modern tooling (like pyproject.toml
).
You want something lightweight and dev-focused.
✅ Use conda
if:
You need non-Python packages (like R, C/C++ libs).
You work with data science or machine learning stacks.
You rely on binary distributions or platform-specific builds.
