Since the last Radar, we¡¯ve gained more experience with , and feedback from teams has been overwhelmingly positive. uv is a next-generation Python package and project management tool written in Rust, with a key value proposition: it¡¯s "extremely fast." It outperforms other Python package managers by a large margin in benchmarks, accelerating build and test cycles and significantly improving developer experience. Beyond performance, uv offers a unified toolset, effectively replacing tools like Poetry, pyenv and pipx. However, our concerns around package management tools remain: a strong ecosystem, mature community and long-term support are critical. Given that uv is relatively new, moving it to the Adopt ring is bold. That said, many data teams are eager to from Python¡¯s legacy package management system, and our frontline developers consistently recommend uv as the best tool available today.
Rust is well suited for writing command-line tools due to its fast startup performance, and we see people rewriting some toolchains in it. We mentioned Ruff, a Python linter written in Rust in the previous Radar. For this volume, we evaluated , a Python package management tool written in Rust. The value proposition of uv is "blazing fast" and it beats other Python package management tools by a large margin in their benchmarks. However, during our Radar evaluation, we discussed whether optimizing within seconds for build tools is a marginal improvement. Compared with performance, what¡¯s more important for a package management system is the ecosystem, mature community and long-term support. That being said, feedback from the project team has shown us that this marginal speed improvement could be a big plus for improving feedback cycles and overall developer experience ¡ª we tend to manually make CI/CD caching very complex to achieve this little performance improvement; uv simplifies our Python environment management. Considering there is still much room for improvement in package and env management for Python development, we think uv is an option worth assessing.
