Hatch vs UV

[kjy5]

This question gets uncomfortably close to just being a platform war but I'm confused about the difference and purpose between Hatch and UV.

At first, I thought UV was a drop-in replacement for pip's virtual environment and package management, but now it looks like it can build and publish as well? That's what I thought Hatch's purpose was (to be one tool to manage environments, packages, build, and publish). Is UV just another shiny tool or does it serve a separate purpose than Hatch? I know Hatch can use UV to in place of pip, but I'm curious about the other features.

Thanks!
