What Benefits Have You Found with the UV Build Backend?

The UV build backend focuses on being user-friendly. It's actively maintained, listens to the community, and its speed is impressive. Sure, it might not have all the features of something like Hatchling, but it’s a solid tool that prioritizes security and efficiency. 🌟

I think UV has potential, but it doesn't yet support build hooks or custom directories like Hatchling does. For now, I would still recommend Hatch unless UV expands its feature set.

One of the biggest advantages I see is its fast dependency resolution and reproducibility. Although it's new and lacks some plugin support, I think it could evolve into a solid choice as it develops.

UV is great for its simplicity—it's less complicated and doesn't do anything unexpectedly, like auto-generating license files. The fact that it’s written in Rust means it’s quicker too! I believe it only needs to cover about 70-80% of basic builds and it’s good enough for most of my projects.

I've tried both the UV build backend and Hatch. Honestly, Hatch has more advanced features like custom hooks before building and the ability to set `__version__` dynamically from git tags. UV is simpler but way faster with better error messages, while Hatch can throw confusing Python exceptions.
